EXECUTIVE SUMMARY Malcolm Pirnie has completed this Reclaimed Water Master Plan to review the existing infrastructure and recommend system improvements for the City of Fort Myers reclaimed water production and distribution system for short term (5-year) and long term (20-year) planning horizons.

The City plans to expand the reclaimed water treatment capacity at the Central AWWTP and construct new production capacity at the South AWWTP for a total reclaimed production capacity of 15 mgd.

Plans to build a third wastewater treatment

plant in the East side of the City will also provide additional reclaimed water capacity to the City. The current reclaimed water distribution system will be expanded to maximize reclaimed water utilization within the City.

Malcolm Pirnie also plans to train City staff to use the GIS model that was prepared for this report of the distribution system production and piping network for future infrastructure planning efforts.

Existing Reclaimed Production and Distribution System The 2.0 mgd capacity Reclaimed Water Production Facility (RWPF) currently produces approximately 700,000 gallons per day of high quality reclaimed water from their Central Advanced Wastewater Treatment Plant (CAWWTP). Secondary effluent generated from the CAWWTP is filtered through sand filters and disinfected with chlorine. A 1-MG ground storage reservoir and 75-horsepower, 150-ft TDH, 1,400 gpm pumps are controlled by variable frequency drives to provide storage and pumping capacity for the distribution system, which currently serves seven users. Nearly 28 miles of irrigation piping have been installed, but not all of the piping is presently serving customers.

Existing System Model The existing reclaimed water distribution system was modeled for the average and peak demands of the current seven users to determine if any existing system deficiencies are present. The average and peak demands of the existing seven reclaimed water users included in the model are summarized in Table ES.1.

The model results showed that the current reclaimed production and distribution system can meet the peak demands of existing City customers and maintain pressure of 45 psi to the Lee County Resource Recovery Facility. The production facilities and piping distribution network for the existing model were then expanded to serve future customers for the future 5-year (2009) and 20-year (2024) model scenarios.

Future Production Improvements For the 5-year future model, the reclaimed water production at the Central Reclaimed Production Facility is expanded to 6.0 mgd capacity and a new 9.0 mgd capacity is built at the South AWWTP. For the 20-year future model an additional wastewater treatment facility with 8.0 mgd reclaimed capacity is built at a new East AWWTP location. The City’s future reclaimed production capacity assumed for the existing and future reclaimed models are summarized below in Table ES.2.

Future Distribution Modeling The future modeling was completed for future 5-year and 20-year scenarios. The production improvements listed above were included.

The new distribution piping

diameters were sized to reduce cost while providing adequate pressure to the reclaimed users for a one week simulation period. The piping routes were chosen for the perceived path of least resistance. The model also included storage for potential interconnections with Lehigh Acres and Gateway, located between the Gateway and Arborwood developments, and with Cape Coral, located at the east end of the Mid Point Bridge.

These interconnections were also locations for offsite storage. The proposed piping grid and interconnection locations for the 2009 and 2024 future scenarios are shown in Figure ES.2.

Costs A summary of the production capacity upgrades, distribution system piping improvements as per the modeling results, and the potential interconnection costs are presented in Table ES.4. A breakdown of the costs for the interconnections and new piping are listed in Tables ES.5, ES.6, ES.7 and ES.8. The production capacity cost for the 5-year planning period includes upgrades to the CRWRF and SRWRF. For the 20year planning period, the production capacity cost accounts for construction of a new East RWPF.

Funding The projected revenues from reclaimed users total $19.8 million over the next 20 years.

The city will need to increase reclaimed rates to cover the cost of the

improvements, or will need to investigate other methods of funding including State Revolving Funds, grants. The cost estimates assume that Lehigh Acres, Lee County, and the City of Cape Coral will contribute 50% of the costs to construct interconnections.

The City could have residential developers complete the installation of some reclaimed transmission mains in return for reduced taxes until the cost of the mains are reimbursed.

Recommendations We recommend the City move forward with reclaimed water production capacity as required by their water and wastewater permits. The distribution of reclaimed water to customers and adjacent municipalities should be maximized by completion of the infrastructure improvements listed above.

We also recommend that the following

initiatives be pursued by the City:

1.0 INTRODUCTION Malcolm Pirnie has prepared this Reclaimed Water Master Plan report for the City of Fort Myers as part of our contract to provide professional engineering services for master planning of the City’s potable water, wastewater, and reclaimed water systems.

This Master Plan is based on an independent evaluation of the reclaimed water distribution system facilities, and provides the City with a plan to prepare for the expansion of the reclaimed treatment and distribution system through the year 2024.

The City of Fort Myers (City) currently produces approximately 700,000 gallons per day of high quality reclaimed water from their 2.0 mgd capacity Reclaimed Water Production Facility (RWPF) located at their Central Advanced Wastewater Treatment Plant (CAWWTP).

The CAWWTP and South Advanced Wastewater Treatment Plant (SAWWTP) have a combined wastewater capacity of 23 mgd AADF and currently treat a combined average of 13 million gallons of sewage each day from both the City and County residents. The City plans to expand the reclaimed water treatment capacity at the Central AWWTP and construct new production capacity at the SAWWTP for a total future reclaimed production capacity of 15 mgd. Plans to build a third wastewater treatment plant in the East side of the City will provide additional reclaimed water capacity to the City. The current reclaimed water distribution system will be expanded to maximize future reclaimed water utilization within the City.

1.1

PURPOSE AND SCOPE This Master Plan will assist the City in planning for increased wastewater effluent

quantities from the City’s treatment facilities, as well as future requirements for an increased effluent disposal through an expanded reclaimed water distribution system.

This Master Plan will provide a guide and a phased system improvements implementation schedule for expanding the City’s reclaimed water system over the next 5 and 20-year planning periods. The purpose of the Master Plan is to develop practical and economical strategies for expanding service and increasing the reclaimed water system customer base, both in the near-term and the long-term.

City of Fort Myers Reclaimed Water Master Plan Section 1: Introduction

Malcolm Pirnie, Inc. 1-1

The goals and objectives of the Reclaimed Water Master Plan project generally include the following: • • • •

Identification of potential future reclaimed water customers.

Projection of future reclaimed water supply, quality, and demands.

Identification of the City of Fort Myers’ costs to serve new customers.

Prioritization of potential customers based on cost to provide service and the volume of use.

A key component of this master planning effort was the development of an interactive GIS model of the City’s reclaimed water distribution system using H2OMAP software. The model was used to analyze existing deficiencies and plan for future demands associated with system growth for 5-year and 20-year milestones. Malcolm Pirnie worked with City planning and growth staff to determine applicable criteria for future modeling scenarios, such as location of future customers, corresponding demands, and City-wide storage requirements.

The model will be turned over to the City at the

end of the Master Planning effort. Malcolm Pirnie will also provide training to City staff for their use of the modeling software.

This Master Plan provides recommendations on distribution storage and pumping requirements and the required pipeline routing to provide service to future customers. A cost estimate is also included for the recommended storage, pumping, and piping improvements.

1.2

PREVIOUS RECLAIMED WATER PLANNING Previous master planning efforts were performed within the City of Fort Myers

that provided the City with a substantial amount of information in regards to a future potential for reclaimed water demand throughout the City.

Future customers were

identified and a basis for reclaimed water demand within the City was established.

1.2.1

1992 Reclaimed Water Master Plan

The City of Fort Myers Reclaimed Water Master Plan was prepared in 1992 by Boyle Engineering. This master plan identified potential reclaimed water demand for various types of users (irrigation, indoor, industrial, and fire), and also determined the

City of Fort Myers Reclaimed Water Master Plan Section 1: Introduction

facility and distribution system modifications necessary for inclusion of a reclaimed water production facility. The projected wastewater and reclaimed production flows at buildout condition from the 1992 Master plan are summarized below in Table 1.1. The report included recommendations for plant upgrades and interconnections between the plants.

This Master Plan was the first step toward developing a comprehensive program to initiate the use of reclaimed water by the City; however few of the recommendations were implemented. Table A.1 provided in Appendix A summarizes the improvements recommended in the 1992 Reclaimed Water Master Plan report.

1.2.2

Effluent Resource Planning Report, March 2001

The City of Fort Myers Effluent Resource Planning Report was prepared by Camp, Dresser, & McKee in March 2001. This document provided an update of the existing reuse supply commitments and identified potential reuse customers to satisfy the estimated future reclaimed water demands. Eighteen potential reclaimed water users were identified, providing a total demand of approximately 7.4 mgd, in addition to the City’s existing 0.7 mgd of reclaimed water demand. Projected reclaimed water demand for 2005 and 2010 was estimated to be 3.8 mgd and 8.1 mgd, respectively. The effluent disposal alternatives of deep well injection and aquifer storage and recovery were evaluated for different combinations of wastewater, reclaimed water, and reverse osmosis concentrate produced at the City’s water treatment plant.

Table A.2 provided in Appendix A lists the improvements recommended in the 2001 Effluent Resource Planning Report. This 2001 Planning Report served as the basis for developing this Reclaimed Water Master Plan.

PLANNING AREA The City wishes to limit the reclaimed planning area to the existing City limits.

Existing reclaimed water piping exists throughout the City and was installed during initial road and development construction. Due to the City’s current priority to target large, bulk users of reclaimed water, some of the pipes are not currently being used to provide flow to customers.

The reclaimed service area has been divided into named service areas, as shown in Figure 1.1, and described below by its bordering streets: • • • • • • • •

Downtown Service Area - downtown area including East and West First Street, the area north of Edison Avenue and west of Evans Avenue.

McGregor Service Area - the area west of Cleveland Avenue and south of Downtown.

Palm Beach Service Area – east of Evans Avenue and north of Michigan Avenue.

Dr. Martin Luther King Jr. Service Area – south of Michigan Avenue and north of Edison Avenue, east of Evans Avenue and to the west of Ortiz Avenue.

Carrel Service Area - east of Cleveland Avenue, west of Interstate 75, north of Colonial Boulevard, and south of Canal Street.

South Service Area - west of Interstate 75 and south of Colonial Boulevard East Service Area - east of Veronica Shoemaker Boulevard, north of Colonial Boulevard and south of Canal Street.

Southeast Service Area - south of Colonial Boulevard and east of Interstate 75 consists of the Southeast service area.

2.0 REGULATORY FRAMEWORK The City’s Reclaimed Water Production Facility and reclaimed water distribution system are governed by numerous Federal, State, and local laws, regulations, policies, and agreements. The reclaimed water system is subject to the regulatory requirements of the United States Environmental Protection Agency (USEPA), the Florida Department of Environmental Protection (FDEP), and the South Florida Water Management District (SFWMD). The reclaimed water system must comply with standards set by the State and the City’s Code of Ordinances including the use of properly treated wastewater effluent, wherever possible.

2.1

REGULATORY BACKGROUND The City of Fort Myers Wastewater Treatment Division consists of two regional

Advanced Wastewater Treatment Plants. The Central Advanced Wastewater Treatment Plant (CAWWTP) is located at 1501 Raleigh Street and is designed to treat 11 million gallons of wastewater per day.

The South Advanced Wastewater Treatment Plant

(SAWWTP), located at 1618 South Drive, is designed to treat 12 million gallons per day.

These plants treat wastewater from all of the City of Fort Myers and much of Lee County. The majority of the treated effluent from the two plants is discharged to the Caloosahatchee River. However, a portion of the Central Plant effluent is diverted to the Central Reclaimed Water Production Facility (CRWPF), located at the CAWWTP, and further treated to reclaimed water standards for irrigation and industrial process purposes.

The CRWPF has a permitted maximum month treatment capacity of 2 million gallons per day (mgd) and a permitted annual average daily flow capacity of 1.51 mgd.

The existing system serves 7 customers with high quality reclaimed water that is used for both industrial and irrigation purposes. Provisions for the CRWPF to be upgraded to a capacity of 6 mgd are currently under way. In addition, design of a South Reclaimed Water Production Facility (SRWPF) with a 9 mgd capacity is currently in the works.

According to the City’s 2000 Water Use Permit, this 15 mgd of reclaimed capacity will satisfy the permit requirements and continue to keep the City in compliance until the year 2015.

City of Fort Myers Reclaimed Water Master Plan Section 2 Regulatory Framework

Malcolm Pirnie, Inc. 2-1

The current CAWWTP permit allows for an annual average discharge of 11 mgd to the Caloosahatchee River and a 1.51 mgd annual average daily flow capacity for the reuse system. The current SAWWTP permit allows for an annual average discharge of 12 mgd to the Caloosahatchee River.

The current wastewater facility permits for

CAWWTP and SAWWTP expire on May 1, 2005 and March 21, 2005, respectively.

2.2

TREATMENT PARAMETERS The Central Reclaimed Water Production Facility performs biological nutrient

removal, tertiary filtration, and high-level disinfection to achieve reclaimed water quality.

The effluent undergoes sample testing to determine the pH and total residual chlorine concentration following disinfection, and the pre-chlorination total suspended solids (TSS) concentration. If each parameter satisfies the regulated limits (pH=6.0-8.5, TSS ≤ 5mg/L, Cl2 ≼ 1mg/L), the effluent is discharged into the reclaimed water storage tank, from where it is withdrawn based on distribution system demand. If these regulated limits are not met, the effluent is sent back to the filter influent.

The typical constituents found in reclaimed water are presented in Table 2.1.

Conventional constituents found in raw wastewater can be treated to reclaimed water quality with most conventional wastewater treatment processes and non-conventional constituents may have to be removed or reduced using enhanced wastewater treatment processes.

Numerous Federal, State, and local policies establish requirements for the operation and treatment of municipal wastewater treatment plants. Various operating parameters and corresponding effluent limitations are regulated and monitored on a regular basis to protect water resources.

Table 2.1 Inorganic and Organic Constituents of Concern in Reclaimed Water Constituent

Measured Parameters

Reason for Concern

Conventional Constituents

Suspended Solids

Volatile and fixed solids

Organic contaminants, heavy metals, etc. are absorbed on particulates. Suspended matter can shield microorganisms from disinfectants. Solids can cause plugging in irrigation systems.

Biodegradable Organics

Biochemical oxygen demand, Chemical oxygen demand, Total organic carbon

Organics provide food for microorganisms, adversely affect disinfection processes, make water unsuitable for some industrial uses, consume oxygen, and may result in health effects if reclaimed water used for potable purposes.

Nutrients

Nitrogen, Phosphorus, Potassium

When discharged to an aquatic environment, nitrogen and phosphorus can lead to growth of undesirable aquatic life.

When applied in excessive levels on land, nitrogen can lead to build-up of nitrate in the groundwater.

Hydrogen Ion Concentration

pH

The pH affects disinfection, coagulation, metal solubility, and alkalinity of the soils. Normal range in municipal wastewater is pH = 6.5 - 8.5.

Residual Chlorine

Free and combined chlorine

Excessive amount of free available chlorine (>0.05 mg/L) may cause damage to some sensitive crops. Chlorinated organics may cause toxicity in groundwater.

Non-Conventional Constituents Stable Organics

Specific compounds (e.g., pesticides, chlorinated hydrocarbons)

Some are resistant to conventional wastewater treatment methods. Some are toxic in the environment and they may limit the suitability of reclaimed water for irrigation or other uses.

Dissolved Inorganics

Total dissolved solids, electrical conductivity, specific elements (e.g., Na, Ca, Mg, Cl, and B)

Excessive salinity may damage some crops. Specific ions such as chloride, sodium, boron are toxic to some crops.

Sodium may pose permeability problems.

Heavy Metals

FEDERAL REQUIREMENTS There are currently no Federal regulations directly governing reclaimed water use.

However, the USEPA regulates many aspects of wastewater treatment and drinking water quality, and the majority of states in the U.S. have established criteria or guidelines for the beneficial use of recycled water. The EPA developed a technical document entitled Guidelines for Water Reuse, which contains such information as a summary of state requirements, and guidelines for the treatment and uses of recycled water. Federal water reuse guidelines are summarized in Table 2.2 below for three different reuse scenarios.

In addition to the reuse guidelines, the EPA also developed secondary treatment regulations in response to the Clean Water Act requirements.

The EPA evaluated

performance data for treatment plants practicing secondary treatment. Reclaimed water is limited to secondary treatment standards established by the EPA. These standard regulations, which are specified in 40 CFR Part 133, apply to the biological treatment component of a municipal wastewater treatment plant and represent the minimum level of effluent quality attainable by secondary treatment, as reflected in terms of BOD5 demand and TSS removal.

Secondary treatment standards, therefore, are defined by the

limitations provided in Table 2.3.

STATE REQUIREMENTS This section discusses the various regulations and permit requirements set forth

by FDEP and SFWMD. State regulations and guidelines govern the required effluent quality for surface water discharge and reuse of reclaimed water. The FDEP is responsible for issuance or denial of operation permits for domestic wastewater facilities based on wastewater effluent quality monitoring and reporting requirements.

The following sections of the Florida Administrative Code (FAC) apply to the supply, treatment, and distribution of reclaimed water.

• • • • •

2.4.1

Chapter 62-600 Domestic Wastewater Facilities Chapter 62-601 Domestic Wastewater Treatment Plant Monitoring Chapter 62-610 Reuse of Reclaimed Water and Land Application Chapter 62-620 Wastewater Facility and Activities Permitting Chapter 62-40 Water Resource Implementation Rule

Florida Department of Environmental Protection

The FDEP is responsible for development and maintenance of rules governing water reuse activity within the state. Reclaimed water treatment, quality, and use are all regulated by the FDEP. The primary document utilized for regulation of reclaimed water is Chapter 62-610 of the FAC. Within this document, guidelines are provided to ensure the level of treatment required for specific uses of reclaimed water, the required reclaimed water monitoring frequencies, and the criteria for land application systems. All reuse and land application systems must be operated and maintained in accordance with Chapter 62-610. Detailed requirements for the design and operational criteria of a wide range of reuse and land application systems are consistent with EPA's Guidelines for Water Reuse, as discussed in Section 2.1 and shown in Table 2.2.

Discharge of reclaimed water or domestic wastewater effluent into waters of the state is regulated by the FDEP.

Both the Central and South AWWTPs currently

discharge the majority of their effluent to the Caloosahatchee River, with the Central plant also discharging part of its effluent into the reclaimed system. FAC Chapter 62-600 contains design, operation, and compliance requirements for all domestic wastewater facilities. Treatment levels, disinfection requirements, and pH requirements also are City of Fort Myers Reclaimed Water Master Plan Section 2 Regulatory Framework

Chapter 62-601 of the FAC establishes the minimum requirements for monitoring of domestic wastewater facilities. Monitoring of various effluent wastewater parameters must be conducted according to the specified frequencies. This regulation ensures that domestic wastewater facilities conduct required monitoring, maintain accurate records, and submit required reports in accordance with the monitoring schedule. Table 2.5 summarizes the minimum schedule required for sampling and testing of wastewater treatment plant effluent.

The FDEP protects surface water bodies by requiring justification for discharge of wastewater effluent rather than another approved means of effluent disposal. The FDEP Antidegradation Policy is contained in Chapter 62-4 FAC, titled Permits, and Chapter 62302, titled Surface Water Quality Standards.

Compliance with the FDEP

Antidegradation Policy must be justified prior to issuance of a permit by FDEP for any new or expanded surface water discharge. The Antidegradation Policy requires a utility, proposing to construct a new discharge or expansion of an existing discharge, to demonstrate that an alternative disposal method such as reuse of domestic reclaimed water is not feasible in lieu of a discharge to surface water, and that the receiving water body will not be adversely impacted by the discharge.

FAC Chapter 62-620 includes permitting requirements for reclaimed water treatment and distribution. Chapter 62-620 offers guidance on the permit for addition of a major user of reclaimed water and the application required for permission to place a public access reuse system in operation. A major user of reclaimed water is defined as anyone using 100,000 gpd or more, based on annual average. All major users must have a FDEP permit authorizing capacity based on type of use or application area. The LCRRF and Eastwood Golf Course are the only two major users currently permitted to receive reclaimed water within the City’s reclaimed water distribution system. The Eastwood Golf Course, however, is a recent addition and is not yet using reclaimed water.

City of Fort Myers Reclaimed Water Master Plan Section 2 Regulatory Framework

Malcolm Pirnie, Inc. 2-8

A public access reuse system involves irrigation of areas that are intended to be accessible to the public, such as residential lawns, golf courses, cemeteries, parks, landscape areas, and highway medians. The City’s CRWPF is currently permitted as a slow-rate public access reuse system (Part III of FAC 62-610), consisting of landscape irrigation of City property, commercial property, and industrial uses. Reclaimed water, at a minimum, must meet secondary treatment and high-level disinfection standards to be allowed for use in public access areas. Filtration must also be provided for control of suspended solids. Prior to disinfectant application, the suspended solids content must be no more than 5 mg/L. The City is currently authorized by the FDEP to provide reclaimed water for “Other Landscape Irrigation and Industrial Uses (cooling water, process water, and wash water at industrial facilities).” The City currently does supply reclaimed water to the Housing Authority, which irrigates residential homes; however, it is under the control of the development and not the individual homeowner. In the future, as more reclaimed water customers are added to the system, many will be residential developments.

Therefore, upon expansion of the system and addition of new users, it will be necessary for the City to gain permission for residential irrigation by the individual homeowners.

For those residential areas that will be newly constructed, the City can make arrangements to supply reclaimed water to an end user, who will then be required to provide it to the entire development. This will allow the City to provide a given quantity of reclaimed water, without the burden of providing storage and pressure for distribution.

2.4.2

FDEP Permit Requirements

Issuance of a Domestic Wastewater Facility Permit by the FDEP constitutes authorization to discharge to waters of the state within limits of the NPDES program.

The FDEP also monitors wastewater effluent quality through enforcement of annual Reclaimed Water or Effluent Analysis Reports.

The following discussion briefly

summarizes the CAWWTP and SAWWTP effluent quality requirements for both surface water discharge and reclaimed water usage.

City of Fort Myers Reclaimed Water Master Plan Section 2 Regulatory Framework

Malcolm Pirnie, Inc. 2-9

Surface Water Both the CAWWTP and the SAWWTP currently discharge the majority of their effluent to the Caloosahatchee River, which is a Class III marine water body. Discharges to the River must meet water quality requirements set forth in each facility’s operating permit, issued by the FDEP. The operating permits for the facilities are issued for 5-year terms and must be renewed upon their expiration. The current wastewater permit for the CAWWTP expires on May 1, 2005. The SAWWTP operating permit expires on March 21, 2005.

Both the Central and South wastewater treatment plants provide advanced wastewater treatment (AWT). Treatment to AWT standards is required to reduce the total nitrogen and phosphorus concentrations regulated for surface water discharge.

Table 2.6 outlines the NPDES permit requirements for both the Central and South plants for surface water discharge.

South Florida Water Management District

Each of the stateâ&#x20AC;&#x2122;s five water management districts has developed its own series of rules designed to implement reclaimed water programs authorized by Chapter 373 of the Florida Statutes and by Chapter 62-40 of the FAC. The SFWMD governs the Fort Myers area and plays a key role in the Water Reuse Program. The SFWMD encourages and directs water users and utilities to use reclaimed water and implement reuse programs.

The SFWMD also offers funding programs that can be used to finance

reclaimed water infrastructure.

Chapter 62-40, entitled the Water Implementation Rule, presents the overall state water policy, providing guidance for issuing consumptive use permits.

This Rule

requires the SFWMD to designate critical water supply areas that either have existing water resources problems or areas in which water resource problems are projected to develop during the next twenty years. Lee County is included in this critical water supply designation.

Under the Cityâ&#x20AC;&#x2122;s Consumptive Use Permit, issued in 2000 for supply to the Water Treatment Plant, the City is required to satisfy certain conditions in order to be in compliance. Conditions within the permit commit the City to make available and utilize 100-percent of the reclaimed water produced within the Fort Myers wastewater service area based on three-month low-flow conditions by March 2005, with a re-evaluation process every 5 years. The permit also requires the City to participate in the design of a regional reclaimed water distribution system as described in the Lower West Coast Regional Water Supply Plan (2000).

The SFWMD has implemented a comprehensive approach to encourage water reuse, including water supply planning, regulation, coordination, and funding. SFWMD completed four regional water supply plans encompassing the land area within the SFWMD jurisdiction.. Each plan contains region specific recommendations on the use of reclaimed water. The SFWMD requires all applicants for Water Use Permits to evaluate the feasibility of implementing water reuse, and it coordinates its reuse activities at the state, local, and water user levels. In addition, the SFWMD has an alternative water supply funding program. The SFWMD has provided over $26 million in alternative

City of Fort Myers Reclaimed Water Master Plan Section 2 Regulatory Framework

Malcolm Pirnie, Inc. 2-13

water supply grants for 113 projects since 1995, including water reuse projects, use of brackish water sources, and aquifer storage and recovery projects.

2.5

CITY OF FORT MYERS CODE OF ORDINANCES REQUIREMENTS The City of Fort Myers Code, Chapter 26: Public Facilities provides several rules

that pertain to reclaimed water use and distribution. Article 5, entitled Reclaimed Water Program, states the procedures and requirements for obtaining reclaimed water service and establishing a connection to the system. The methodology used for installation, sizing, and funding of the reclaimed water system is also included. Chapter 26, Article V of the City’s Code is attached in Appendix C. The City’s Ordinance states that the sources of reclaimed water shall comply with certain FDEP regulations as they may apply to the project. The sources of reclaimed water must also comply with state and local health department regulations and should gain approval prior to utilization. Table 2.9 lists various subparts within Chapter 17-6 of the FAC, as presented in the City’s Code of Ordinances.

Chapter 17 is titled Department of Environmental Regulation, with 17-6 relating more specifically to Wastewater Facilities. The Department of Environmental Regulation in 1993 merged with the Department of Natural Resources to form the FDEP. Currently, the FDEP regulates wastewater facilities through Chapter 62 of the FAC, as described in Section 2.4.1, which includes updated information of that contained in Chapter 17.

The City’s Code of Ordinances states that the City shall develop and maintain a reclaimed water master plan, which should include areas where construction and use of a reclaimed water system and pipeline transmission system are encouraged. The use of City of Fort Myers Reclaimed Water Master Plan Section 2 Regulatory Framework

Malcolm Pirnie, Inc. 2-14

reclaimed water is separately metered for each connection and appropriate rates are established by the City Council. Currently, City infrastructure exists to supply reclaimed water to developments for lawn irrigation, parks, golf courses, and open space in and adjacent to the City. However, for new development areas, a separate reclaimed water distribution system shall be installed in accordance with City engineering and construction standards.

Identification of the reclaimed water system must include special considerations to avoid cross connections with the potable water system. Cross connection control is addressed in the Cityâ&#x20AC;&#x2122;s existing Code of Ordinances, Chapter 26. Chapter 26-211 states that: The reclaimed water distribution system shall include special considerations to avoid cross connections with the potable water system. The following features shall be included in reclaimed water systems to protect the public health: (1) (2) (3) (4) (5)

Reclaimed water distribution systems shall be constructed with brown PVC pipe or purple with yellow block letters color-taped ductile iron pipe.

Square valve box covers painted brown to distinguish from round potable water system valve boxes.

Brown strip on street curb to identify reclaimed water customer.

Backflow preventers installed on potable water service connection.

Reclaimed water meters color coded with tape to distinguish from potable water meters (where applicable). Meters, covers and meter box covers should be cast to indicate reclaimed water.

Chapter 26, Article X: Cross Connection Control Standards, is provided as Appendix D. This section does not specifically address reclaimed water concerns, and should be updated with similar language to Chapter 26-211. Also, additional standards should be developed to have double check valves, or reduced pressure backflow prevention devices installed at locations that have high risks for cross connections. The City should develop a schedule to periodically inspect reclaimed water services to assure that the cross connection requirements are being followed. Enhanced inspection efforts and education efforts will be required before residential or small commercial reclaimed water users are served by the City, as per the FDEP requirements in FAC 62-610.470 and 62-555.360.

3.0 FORT MYERS RECLAIMED WATER SYSTEM The City of Fort Myers operates two wastewater treatment facilities. Only the CAWWTP currently has reclaimed water production capabilities. Currently, reclaimed water is used for landscape irrigation and industrial use. This section describes the existing reclaimed water system, identifies the current Fort Myers reclaimed water users, and describes the Cityâ&#x20AC;&#x2122;s public involvement and community education activities related to the reclaimed water program.

3.1 WASTEWATER TREATMENT FACILITIES The Cityâ&#x20AC;&#x2122;s two treatment facilities process wastewater from all of the City of Fort Myers and much of Lee County. Figure 3.1 illustrates the general location of both the South and Central advanced wastewater treatment facilities.

3.1.1

General

The CAWWTP and SAWWTP each have eleven operators, over a total of three shift periods, allowing for operation of the plant 24 hours per day, seven days per week.

In addition to the treatment operators, each plant has necessary staff to assist with the maintenance of the facility. The Central plant staff, with the exception of the residuals operators, also work with the reclaimed CRWPF when necessary. The Organization Chart in Figure 3.2 shows the staffing allocation at the Central and South treatment plants.

3.1.2 Wastewater Treatment Capacity The CAWWTP currently has a permitted treatment capacity of 11 mgd. From January 1997 to May 2003 the annual average flow for the Central plant was around 6.6 mgd. The SAWWTP currently has a permitted treatment capacity of 12 mgd. From October 1997 through May 2003 the annual average flow was around 6.9 mgd.

Addition of aluminum sulfate (AlSO3) prior to clarification allows for the precipitation of phosphorus. The solids are then settled within the clarifiers and the clear effluent is disinfected with chlorine, dechlorinated, and finally discharged to the Caloosahatchee River. The solids removed from the clarification process are stabilized in aerobic digesters, dewatered using belt filter presses, and land applied as fertilizer.

Next, the removal of phosphorus is performed through the addition of aluminum sulfate (AlSO3).

The solids are then settled within the clarifiers and

Figure 3.5 Clarifiers at the Central AWWTP

are either returned to the process or dewatered and disposed of through land application.

Figure 3.5 shows a picture of the clarifiers at the Central plant. The clear effluent from the clarifiers is disinfected with chlorine, dechlorinated, and either discharged to the Caloosahatchee River or sent to the on-site Reclaimed Water Production Facility (discussed in Section 3.2). The solids removed from the process are stabilized in aerobic digesters, dewatered using belt filter presses, and land applied as fertilizer.

3.2 RECLAIMED WATER PRODUCTION FACILITY The City of Fort Myers operates the Central Reclaimed Water Production Facility (CRWPF), located at the CAWWTP, which is currently the Cityâ&#x20AC;&#x2122;s only reclaimed water production facility. The City is currently planning for expansion of the Central RWPF and for the construction of a second reclaimed water facility at the South AWWTP. Figure 3.1 illustrates the general location of both the Central and South reclaimed water production facilities, once completed.

City of Fort Myers Reclaimed Water Master Plan Section 3 Fort Myers Reclaimed Water System

Malcolm Pirnie, Inc. 3-3

3.2.1

General

The reclaimed water system operation began in 1994, and has grown to an annual demand of approximately 253 MG of reclaimed water in 2003.

3.2.2

Treatment Capacity

The CRWPF is designed for 2.0 mgd and also has a maximum month permitted capacity of 2.0 mgd and an annual average permitted capacity of 1.51 mgd.

3.2.3

Treatment Process

Secondary effluent generated from the CAWWTP enters the CRWPF and is filtered through sand filters. Filter effluent is disinfected with chlorine for public-access irrigation and distribution to various reuse sites. Figure 3.6 shows a picture of the filter building. A basic diagram of a reclaimed water treatment process and potential end users is

Figure 3.6 CAWWTP Filter Building

shown in Figure 3.7.

3.2.4

Onsite Finished Storage

Onsite ground storage at the Central RWPF provides 1-MG of storage capacity.

Figure 3.8 shows the storage tank and corresponding effluent piping. The storage tank measures 90 feet in diameter and has a maximum water depth of 20 feet.

3.2.5

Distribution System

Reclaimed water is pumped from the 1-MG storage tank into the distribution system using variable speed pumps. Two 75-horsepower, 150-ft TDH, 1,400 gpm pumps

are

controlled

by

variable

frequency drives, which vary the pump impeller revolutions per minute and flow to maintain a constant discharge pressure.

Typically, the distribution system pressure

Figure 3.8 Central RPF Storage Tank and Effluent Piping

is maintained at 63 pounds per square inch (psi).

The piping network supplies golf courses, City parks, landscaping, and industrial users with reclaimed water throughout the distribution system. The distribution system network consists primarily of 28 miles of pipelines ranging in diameter from 4 to 24 inches. The piping consists of mainly polyvinyl chloride pipe (PVC) and ductile iron pipe (DI), with the smaller diameter piping being PVC.

Table 3.1 shows the

approximate length of the distribution network piping classified by diameter and material.

Existing Users

The Central Reclaimed Water Production Facility currently provides reclaimed water to seven customers in the Cityâ&#x20AC;&#x2122;s service area. Each of the seven users and their corresponding usage schedules are described in the following paragraphs. Figure 3.9 illustrates the general location of each of the existing users, as well as the existing distribution pipelines that supply each of the users with reclaimed water.

Red Sox Training Park The Red Sox training facility irrigates on Monday, Wednesday, Friday, and Saturday. There are ten zones that irrigate the infield and sidelines four times a week for approximately 10 minutes each. The facility also has forty zones that irrigate the outfield four times a week for approximately 15 minutes. The facility also has six zones that serve the common grounds around the ball fields that run for approximately 15 minutes, four times a week. Watering begins at around 9 pm for each of the zones.

Malcolm Pirnie, Inc. 3-6

J.B. Schultz City Nursery The City Nursery uses reclaimed water three times a week between the hours of 7 am and 11 pm. Figure 3.10 shows the nursery during an irrigation cycle. Plants are watered Monday, Wednesday, and Friday mornings, as needed.

During periods of heavy rain, the Wednesday

cycle is eliminated. This location will be moved to the East on Buckingham Road in the future (at the time of the future

Figure 3.10 J.B. Schultz City Nursery

Eastwood Golf Course expansion, discussed in Section 5.3).

City of Fort Myers Water Treatment Plant The Cityâ&#x20AC;&#x2122;s Water Treatment Plant uses reclaimed water for site irrigation only. A twenty-six zone sprinkler system operates for approximately thirty minutes each day.

Each zone operates on a five minute delay and therefore operation begins as early as 7 pm and finishes around 8:30 am.

Lee County Resource and Recovery Facility (LCRRF) This facility uses reclaimed water twenty-four hours per day, seven days a week. Figure 3.11 shows the LCRRF. The LCRRF uses the reclaimed water for such purposes as processing, washing, and cooling within the facility. The facility has 15,600 gallons of storage onsite. Upon completion of a new expansion in 2005, the reclaimed water consumption will increase by one-third. The LCRRF is currently the only

Figure 3.11 Lee County Resource and Recovery Facility

industrial user of reclaimed water; however, it accounts for the largest portion of reclaimed water use within the City of Fort Myers. It is also the only current reclaimed customer permitted as a major user (greater than 100,000 gpd).

Buckingham Community Park The use of reclaimed water at Buckingham Park consists of irrigation of the baseball field, football field, and various other landscaping throughout the park. An City of Fort Myers Reclaimed Water Master Plan Section 3 Fort Myers Reclaimed Water System

estimated 15 minutes per cycle and two cycles per day allows for the baseball and football fields to be watered 6 days per week, Sunday through Friday. The general landscape irrigation consists of 15 to 30 minute cycles, once per day, for 6 days a week, Sunday through Friday.

Dr Martin Luther King Jr. (MLK) Median Irrigation The reclaimed irrigation system in operation on Dr. Martin Luther King Jr. Boulevard operates on Monday, Wednesday, and Friday. Irrigation lasts for 10 to 15 minutes per zone during the early morning hours. During periods of heavy rain, the Wednesday cycle is eliminated. Figure 3.12 shows a section of MLK where irrigation is performed using reclaimed water.

Figure 3.12 Median Irrigation on Dr. Martin Luther King Jr. Blvd.

Housing Authority The Housing Authority waters for irrigation purposes solely. A twenty-four zone system alternates so that twelve zones are watered each morning.

Operation lasts

between 12 am and 6 am.

3.3.2

User Characteristics

Each of the current seven reclaimed water customers primarily use reclaimed water for irrigation purposes. Only five of the users were originally accounted for in the Central AWWTF permit issued in May of 2000.

The remaining three users were

previously identified and have since become included in the Cityâ&#x20AC;&#x2122;s reclaimed water system. Table 3.2 provides a summary of each of the users and their corresponding acreage and permit capacity information from the CAWWTP operations permit.

Historical Reclaimed Water Use

Table 3.3 shows historical annual average reclaimed water usage by user for the years 1998 through 2003. Among the current users, the most common use for reclaimed water within the City is irrigation of public parks and landscaping. However, the largest user of reclaimed water is Lee Countyâ&#x20AC;&#x2122;s Resource and Recovery Facility. In 2003, the LCRRF accounted for the majority of all reclaimed water use. The remainder of the reclaimed users, practicing reuse through irrigation, accounted for less than 15 percent of the total reclaimed water use.

It is estimated that the total reclaimed water demand, from the seven existing users, will increase to approximately an annual average of 1.3 mgd, as a result of Eastwood Golf Courseâ&#x20AC;&#x2122;s demand. Table 3.4 summarizes the average demand, maximum individual user monthly demands, and the demands used during the overall maximum month for each user. Figure 3.13 shows the annual average reclaimed water demand from 1998 through 2004 for each of the existing customers.

Evaluating each of the various reclaimed users and their peak month demands over the course of January 1998 to February 2004, revealed that the maximum month of reclaimed use (the combined demand for each user) was in March of 2003. The total reclaimed usage was approximately 1.15 mgd. Figure 3.14 depicts the proportional distribution of reclaimed usage during the maximum month with respect to each of the current users.

Seasonal Trends

In many areas, the amount of reclaimed water use varies each year based on the time of year and the corresponding rainfall conditions. Generally, in Florida, the summer months would correspond to a lower reclaimed demand due to the higher amount of rainfall. However, since the largest reclaimed user for the City of Fort Myers, the

City of Fort Myers Reclaimed Water Master Plan Section 3 Fort Myers Reclaimed Water System

Malcolm Pirnie, Inc. 3-11

LCRRF, demands reclaimed water year around, regardless of seasonal conditions, the seasonal rainfall induced trend in reclaimed water use is mitigated. Figure 3.15 shows the monthly trends for 1997 through 2003.

The variation in flow for each particular year corresponds to specific user demand fluctuations. The existing reclaimed water customers obtain reclaimed water directly from the system whenever a demand exists. The LCRRF receives a continuous flow of reclaimed water each day of the year at much larger quantities than the other users.

Therefore, the depicted trend tends to only mirror the LCRRF usage, being that its demand is approximately an order of magnitude larger than the demand of the other users. In the future, as additional non-industrial users are added, a seasonal trend may become more evident.

Historical Potable Water Irrigation Use

The City currently supplies potable water to its users for irrigation purposes through approximately 564 metered connections that are strictly for irrigation. Table 3.5

Most of the potable water used for irrigation is provided through residential and commercial connections. The quantity of potable water used for City-wide irrigation can be reduced through expansion and connection to the reclaimed water distribution system.

Many of the City properties currently being irrigated with potable water, such as golf

courses and residential neighborhoods, can be irrigated using reclaimed water, creating a substantial savings for the City.

3.4

EXISTING SYSTEM CONFIGURATION This section discusses the system deficiencies, planned improvements to the

system, and the current rate structure for reclaimed water.

3.4.1

Perceived System Deficiencies

The following concerns were evaluated to be production capacity and distribution system deficiencies.

Production Facilities Currently, the only source of reclaimed water for the City is the Central RWPF. The SAWWTP, although not currently producing reclaimed water quality effluent, will in the near future contribute to the reclaimed water distribution system. However, until that time the South plant will remain the only facility within Lee County, treating greater than 100,000 gpd, which does not produce any reclaimed water.

Within the Cityâ&#x20AC;&#x2122;s Consumptive Use Permit, it is required that the City utilize 100percent of the reclaimed water produced by 2005. Currently this requirement is not being met, however by 2005, the City should plan for implementation of a regional reclaimed water distribution system to achieve complete utilization.

The existing reclaimed water production facility at the Central plant is designed for an annual average flow of 1.51 mgd. Therefore, the City must also consider the equipment upgrades necessary at the CRWPF to produce future reclaimed water at 100percent.

Distribution System It is important for the City to operate the reclaimed water production facility to maintain system storage at or near maximum levels to minimize fluctuations in system storage. Those reclaimed water systems supporting users who require reclaimed water at

City of Fort Myers Reclaimed Water Master Plan Section 3 Fort Myers Reclaimed Water System

Malcolm Pirnie, Inc. 3-14

various times of the day, typically require a large amount of system storage and/or extra treatment and production capacity to meet higher peak demands. Those reclaimed water systems supporting users with onsite storage rely on customer storage to dampen peak demands on the system, and, thus, typically require less system storage and production capacity.

Currently the City delivers reclaimed water to seven customers, only one of which has onsite storage capabilities, the Lee County Resource and Recovery Facility. The LCRRF, also the largest current reclaimed water user, maintains onsite storage allowing them to meet daily peaks without relying on the reclaimed water distribution system to deliver water to them at their peak flow rate.

The CAWWTP site, unfortunately, does not allow for construction of additional system storage due to space constraints. Future expansion of the reclaimed water system, production and distribution, will require construction of storage facilities to accommodate peak demands on the system. Additional reclaimed water storage will be necessary in the distribution system for expanded distribution system supply.

3.4.2

Planned Improvements

Capital improvements to the reclaimed water treatment and distribution system are budgeted annually through the City of Fort Myers Capital Improvement Program (CIP). The current CIP includes expansion of the Cityâ&#x20AC;&#x2122;s reclaimed water facilities, connection of additional reclaimed water users, and miscellaneous system-wide renovations of the sewer collection mains, each of which are discussed below.

Production Facilities Reclaimed water expansion at the CAWWTP is estimated to be complete before the end of 2006 and construction of a new reuse facility at the SAWWTP is estimated to be complete by 2010. During this reclaimed water system upgrade, many of the plant components will be expanded and/or constructed. New transmission and distribution piping and possibly new system storage will expand and improve operation of the Citywide reclaimed water system.

City of Fort Myers Reclaimed Water Master Plan Section 3 Fort Myers Reclaimed Water System

Malcolm Pirnie, Inc. 3-15

Distribution System As the capacity of the reclaimed water production facilities increase, the City will need to begin to bring more and more reclaimed water users online.

Within the

upcoming CIP, the City plans to add reclaimed water service to the Heritage Palms area.

Also on the CIP is a multi-phased water and sewer rehabilitation and replacement program addressing aging water and wastewater system components. Figure 3.17 shows the City’s repair and replacement scheduled Phases. Several areas have already been rehabilitated, and all work scheduled should be completed by the end of 2010.

For those upcoming water and sewer rehabilitation Phases III C, and IV through VII, the City should consider installation of the proposed reclaimed water pipelines within those areas simultaneously to avoid multiple infrastructure repairs. For example, Phase IV of the rehabilitation program, to be completed in 2008, will take place in the area around the Fort Myers Golf Course, where installation of reclaimed water piping is proposed. Construction of the reclaimed water transmission pipes in conjunction with the water and sewer system modifications will allow for fewer disturbances to the City’s roadways and City’s residents.

3.4.3

Billing Rates

The use of reclaimed water is separately metered for each connection, as is the case for potable water, and appropriate rates are established by the City Council for the use of reclaimed water. Applicants requesting reclaimed water service shall submit the appropriate application form to the public works administrator.

Review of each

application is performed and a determination is made as to the adequacy of existing reclaimed water production facilities. The applicant is notified if a sufficient quantity of reclaimed water exists and connection to the system is possible. The current rate for reclaimed water is $0.5748 per 1000 gallons used. Expansion of the reclaimed water system and connection of additional users may result in an increase in the current billing rate. The billing rate should be reevaluated upon completion of the production facility expansions, as well as following expansion of the distribution system.

The current billing rate, $0.5748 per 1000 gallons, for reclaimed water within the City of Fort Myers is slightly higher than that of other utilities in the area. The reclaimed City of Fort Myers Reclaimed Water Master Plan Section 3 Fort Myers Reclaimed Water System

Malcolm Pirnie, Inc. 3-16

FIGURE 3.17

water billing rate for residential users in Collier County is approximately $0.42 per 1000 gallons and the average billing rate for all counties in Florida is approximately $0.34 per 1000 gallons. Although the Cityâ&#x20AC;&#x2122;s rate appears to be high compared to other utilities, it is significantly lower than the Cityâ&#x20AC;&#x2122;s potable water rate of $3.03 per 1000 gallons.

Various sources of funding are available in the form of loans and grants from the FDEP, SFWMD, and the EPA. Funding available through the FDEP includes the State Revolving Fund Loan Program, providing low-interest loans for planning, design, and construction of wastewater facilities. The SFWMD provides grants to those utilities that develop cost-effective reclaimed water supplies. Finally, the EPA makes funds available for water supply projects through its State and Tribal Assistance Grant program. Receipt of any form of this funding would contribute to the initial project capital costs and allow for a reduced customer billing rate.

4.0 EVALUATION OF EXISTING SYSTEM The existing distribution system was modeled and evaluated for a one week simulation period using demands and weekly demand patterns specific to each user.

Each of the existing pressurized pipes transmitting water to the City’s seven existing reclaimed customers was included in the model. This evaluation includes a comparison of the average and peak flow showing the following: • • • • •

DISTRIBUTION SYSTEM HYDRAULIC MODEL

Modeling of the City’s reclaimed water distribution system was completed using H2OMAP software by MWH Soft, Inc. The H2OMAP software simulates hydraulic behavior of the reclaimed water system by simulating various elements based on time of day, tank water levels, system pressure, node demands, pipe size, roughness, and minor losses. The model was built by compiling the following data: • • • • • • • • •

Reclaimed water metering and billing information Elevation data GIS land parcel data Future planned development data Existing infrastructure CAD drawings As-built construction drawings Historical demand data Wastewater treatment plant pressure and flow SCADA data Pump manufacturer information

City of Fort Myers Reclaimed Water Master Plan Section 4: Evaluation of Existing System

Malcolm Pirnie, Inc. 4-1

The system demands are simulated using 168 hourly demand factors multiplied by an average weekly demand value for each customer. Average customer demands were used to simulate an Existing Average Demand Scenario that was used for calibrating the model. Maximum customer demands were used to simulate an Existing Maximum Demand Scenario that was used to evaluate for system deficiencies. The pumps and tank levels are modified within the model based on treatment and storage capacity, valve settings, tank levels, and pressure settings.

4.2

SYSTEM PERFORMANCE CRITERIA

The performance criteria that were used to evaluate the Existing Maximum Demand Scenario for system deficiencies are summarized below in Table 4.1.

CAWWTP and CRWPF Capacity Limitations

The existing Central AWWTP can treat up to 11 mgd AADF. The existing model includes effluent flow from the Central AWWTP that varies hourly as per the average hourly flow pattern at the plant, and averaged to 7.0 mgd of effluent flow. The CRWPF can treat up to 2 mgd of water for reclaimed storage and distribution. The reclaimed water production process is currently limited by the filter capacity. The model flow into the storage tank is limited to a maximum flow of 2 mgd. The tank will not fill if it is already at its maximum level. The remaining CAWWTP effluent is discharged to the river.

City of Fort Myers Reclaimed Water Master Plan Section 4: Evaluation of Existing System

Malcolm Pirnie, Inc. 4-2

4.2.2

Distribution Pump Capacity

The reclaimed distribution system is pressurized by two 2 mgd pumps that are operated by variable frequency drives to maintain a pressure of 62 psi leaving the Central RWPF. Therefore the maximum flow from the CRWPF is limited to 4 mgd.

4.2.3

System Storage

One 1 mgd tank provides storage for reclaimed distribution. The tank is modeled as a cylindrical tank with a 90 ft diameter that is 20 ft tall.

4.2.4

Distribution System Pressure Requirements

Reclaimed distribution systems should be modeled to provide water to customers at a minimum pressure of 20 psi. The City’s interlocal agreement with the County requires that pressure at the LCRRF be maintained at 45 psi. Since the LCRRF is the largest and second farthest user in the reclaimed distribution system, the minimum pressure requirement in the distribution system will be 45 psi.

4.2.5

Distribution System Head Loss Requirements

The maximum acceptable headloss per 1000 ft should remain below 3 ft per 1000 ft, to keep from having significant pressure loss across the pipe. The model will evaluate each pipe within the existing distribution system for this criterion.

Reclaimed water must flow through approximately 32,000 ft of piping to reach the LCRRF. The LCRRF is approximately 10 ft higher in elevation than the CRWPF. The maximum head loss that can occur between the CRWPF and LCRRF can be calculated by the subtracting the minimum pressure at the LCRRF from the pressure leaving the CRWPF, converting the pressure loss to head loss, and subtracting the head loss due to the elevation change. The maximum head loss that can occur between the CRWPF and LCRRF is:

((62 psi – 45 psi)*2.31 ft/psi ) – 10 ft = 29.23 ft

City of Fort Myers Reclaimed Water Master Plan Section 4: Evaluation of Existing System

Malcolm Pirnie, Inc. 4-3

Dividing the maximum head loss by the distance between the two facilities allows for the maximum head loss per 1000 ft to be calculated. This head loss per 1000 ft equals:

29.23 ft / 32,000 ft = 0.91 ft / 1,000 ft

The weighted average of the head loss per 1,000 ft must not exceed this value to maintain a pressure of 45 psi at the LCRRF. Some pipelines may have higher headloss values along the pipeline route, however, as long as the weighted average remains less than 0.91 ft / 1000 ft, the distribution system pressure can be maintained.

Model Calibration

The existing average scenario was used to complete the calibration of the model.

Calibration of the distribution model was completed by modifying flow patterns or pipe roughness coefficients to match available distribution flow and pressure data to the model output. The City provided hourly reclaimed water data for flows distributed from the CRWPF recorded from 9/1/2003 â&#x20AC;&#x201C; 11/23/2003. A comparison of the actual maximum, minimum, and average hourly flows leaving the Central RWPF and the sum of the hourly customer demands used in the existing average scenario are shown in Figure 4.4. The average demands and the overall recorded average flow from the CRWPF are both approximately 0.873 mgd (606 gpm.)

Scenario. A staff member from the LCRRF verified that the resulting pressures from the existing Model were consistent with the pressures they receive at their facility.

Since most of the piping was installed within the last 10 years, the roughness coefficient of the ductile iron and PVC piping has most likely not changed much for the duration of their installation. Therefore, the model results are assumed to be fairly accurate and not affected by to corrosion, calcification, or biological growth.

CAWWTP AND CRWPF EFFLUENT FLOW ANALYSIS

One of the benefits of reclaimed water distribution in the City of Fort Myers area is the reduction of effluent flows from the CAWWTP to the Caloosahatchee River. A summary of the total effluent volumes from the CAWWTP and the CRWPF for the average demand and the maximum demand scenarios for the 1-week simulation is summarized in Table 4.6.

5.0 FUTURE RECLAIMED WATER SUPPLY AND DEMANDS This report section summarizes the future reclaimed water supply and usage potential and other effluent disposal options for the Cityâ&#x20AC;&#x2122;s wastewater treatment plants.

Design for treatment upgrades is already underway to expand reclaimed water production at the Central and South AWWTP to 6.0 mgd and 9.0 mgd, respectively. A new East AWWTP is assumed to contribute an additional 8.0 mgd of reclaimed water treatment capacity by the end of 2009. The new user demands were calculated based on land area and usage type. The total demands are quantified for the future 5-year and 20-year scenarios.

Additional methods for reclaimed water storage and disposal are also

discussed in this section.

5.1

FUTURE RECLAIMED WATER SUPPLY The amount of reclaimed water that will be available in the future will be limited

to the amount of wastewater flowing to the wastewater treatment plants, and the amount of effluent that is treated to reclaimed water standards. The City and County areas served by the CAWWTP and SAWWTP will experience increases in flow due to population growth and expansion of their individual service areas. The City will also expand the reclaimed water production capacity at their existing plants and will most likely build a third plant that will utilize 100-percent reclaimed effluent disposal.

5.1.1

Treatment Capacity

The CAWWTP and SAWWTP wastewater treatment capacities will remain 11 mgd and 12 mgd, respectively, in the future as there is no room onsite for expansion of the wastewater treatment processes. The maximum reclaimed production capacity will be 6.0 mgd at the CAWWTP and 9.0 mgd at the SAWWTP. Previous sewer system master planning studies performed for the City indicated the necessity of a third wastewater treatment plant in the East Service Area. Malcolm Pirnie also confirmed this conclusion in the Wastewater Master Plan. We recommend that a new 8.0 mgd Maximum Three month Rolling Average Daily Flow capacity wastewater treatment plant

City of Fort Myers Reclaimed Water Master Plan Section 5: Future Reclaimed Water Supply and Demand

Malcolm Pirnie, Inc. 5-1

be operational by the end of 2009. We will assume that this new plant will have 100% reclaimed treatment capacity. The wastewater treatment and reclaimed water production capacity of the Cityâ&#x20AC;&#x2122;s treatment facilities in the future are summarized in Table 5.1.

IDENTIFICATION OF NEW POTENTIAL RECLAIMED WATER USERS The process used to identify potential future reclaimed water customers included

discussions with City government staff, review of previous studies to identify sites that could potentially use reclaimed water for existing and projected water demand, and also review of information received from the Lee County Planning and Parks Departments.

Many of the proposed users are existing residential developments, parks, and golf

City of Fort Myers Reclaimed Water Master Plan Section 5: Future Reclaimed Water Supply and Demand

Malcolm Pirnie, Inc. 5-2

courses. Other proposed users are future residential developments, and parks and golf courses that have not yet been constructed.

5.2.1

Previous Studies Review

Two previous studies were reviewed to identify potential existing and future reclaimed water customers. The City of Fort Myers Effluent Resource Planning Report (Camp, Dresser, & McKee, 2001) and the Master Plan for the Regional Irrigation Distribution System (RIDS) For the Lower West Coast Region (SFWMD, 2002) both helped to identify potential reclaimed water customers within the planning area. The Effluent Resource Planning report assisted in estimating the number of future customers, as well as calculating the corresponding demands for each user.

The RIDS report

provided information on a potential means of effluent disposal to adjacent municipalities in the future.

5.2.2

Discussions with City Staff

A workshop was held with City staff to investigate potential new reclaimed water customers within the planning area. Information was gathered and reviewed with the help of a City planning area map and a City aerial, locating existing and planned golf courses and residential developments.

Most of the sites identified were existing

properties, requiring installation of a minimal amount of new transmission pipe, due to their proximity to existing reclaimed water distribution piping. However, some of the sites are existing residential developments that would require a significant amount of roadway construction and repair to install distribution piping. Directional drilling could also be used as an alternate construction method in those locations to minimize road damage, but this would increase construction costs.

Many of the sites identified were future golf courses and residential developments not yet constructed. These sites may require a greater amount of new pipe to connect to the reclaimed water system, due to their distance from the existing system. However, the reclaimed water transmission piping for these sites could be installed at the time of site construction, avoiding any unnecessary roadway repairs.

5.2.3

Correspondence with City Departments and Developers

The Cityâ&#x20AC;&#x2122;s Planning and Zoning, and Parks and Recreation departments were contacted to identify planned developments or recreational facilities that could use reclaimed water. Many of the locations that were identified are existing sites constructed prior to the reclaimed water transmission pipelines. Also, the City Planning Department assisted in estimating the approximate timeframe and priority of each new user to begin operation. Several developers also shared their irrigation permits and attended Reclaimed Water Master Planning meetings to investigate the possibilities of receiving reclaimed water.

5.3

FUTURE USER DEMANDS Future reclaimed water use sites include a total of sixty-five new irrigation areas

and one new industrial use. The maximum demands of these future users will determine the sizing of the future distribution system transmission and distribution mains, and the treatment plant storage and pumping capacity.

5.3.1

Calculation of Future User Maximum Demands

Irrigable acreage was calculated for each irrigation user by estimating the amount of available onsite area capable of receiving reclaimed water. It was assumed that 30 percent of the total residential and commercial development area, 80 percent of the total park area, and 60 acres for every nine holes of the golf course would be irrigated. The maximum demand was calculated at a rate of one inch per week over the irrigated acreage.

The industrial usage at the LCRRF was determined from the interlocal

agreement between Lee County and the City. The land area, estimated demand, and future year they will be connected are listed in Table 5.3. The total maximum reclaimed demands for existing and future users are summarized in Table 5.4.

Demand Patterns

The demand patterns for the existing users will continue to be the same for the future Model scenarios. We have also made the assumption that all users with demands larger than 100,000 gpd will have their own onsite storage, and will have the same constant demand pattern that was used for the LCRRF. Future users with less than 100,000 gpd will have demand patterns equal to the existing user that their use will be most similar, as shown previously in Figure 4.1. Additional demand patterns were created for residential and commercial customers with a peak demand factor of 1.5 and a minimum demand factor of 0.5. A general pattern was also developed for parks, which is identical to the Water Treatment Plant pattern. The demand patterns for each new user are listed in Table 5.6

Discharge to the Caloosahatchee River

Discharging to the Caloosahatchee River is the existing method used by the City to dispose of excess wastewater effluent and reclaimed water produced. The FDEP has several new laws and future objectives limiting the potential for future increases in surface water discharge of treated wastewater. The City will need to identify alternatives for disposal of wastewater effluent and reclaimed water as the Florida implementation of the Federal guidelines of the Total Maximum Daily Load (TMDL) program become more defined.

City of Fort Myers Reclaimed Water Master Plan Section 5: Future Reclaimed Water Supply and Demand

Malcolm Pirnie, Inc. 5-12

The TMDL, as defined in Section 303 (d) of the Clean Water Act, is the identified maximum amount of pollutant that a water body can receive and still meet its designated water quality standards. States are required to implement TMDLs and attain water quality standards as set by each facilityâ&#x20AC;&#x2122;s discharge permit. The Caloosahatchee River is in Group 3 of the Basin rotation schedule. The FDEP has completed the first two phases (watershed evaluation, and the monitoring and assessment) and will complete the third phase of developing and implementing TMDLâ&#x20AC;&#x2122;s by the end of 2004. An action plan will be developed for the fourth phase in 2005 and implemented in 2006 as the fifth phase.

Surface water dischargers will be evaluated for their specific pollutant contributions into these impaired waters. Surface water discharge, particularly any proposed expansions or increases in quantity, are heavily reviewed by the FDEP. The City should be able to continue use of this disposal option in a reduced capacity for the CAWWTP and SAWWTP. This option, however, will not be an option for the new East WWTP, because it is several miles from the Caloosahatchee River.

5.4.3

Rapid Infiltration Basins

Reclaimed water can be used to replenish groundwater through the use of rapid infiltration basins (RIBs). The infiltration basins are designed to accelerate percolation through the soil and unsaturated zone, removing total suspended solids in the process and allowing the filtered reclaimed water to reach the groundwater for future extraction.

Although recharge of groundwater with reclaimed water has obvious advantages for water management, some disadvantages also exist. RIBs require a large amount of land surface area to allow for percolation. Also, there is the potential for contamination of the underground aquifer by the reclaimed water.

Limitations on water quality, physical characteristics of basins, setbacks from potable water supply wells, and design and operation requirements are discussed in FAC 62-610. Limits are present on total organic carbon (TOC) and total organic halogen (TOX) in reclaimed water for groundwater recharge in order to reduce the risks related to non-conventional and toxic constituents. The concentration of nitrate in reclaimed water used in RIBs may not exceed 12 mg/L (as nitrogen) to protect groundwater from nitrate

City of Fort Myers Reclaimed Water Master Plan Section 5: Future Reclaimed Water Supply and Demand

Malcolm Pirnie, Inc. 5-13

contamination. This limit also ensures that the concentration in groundwater is less than 10 mg/L nitrate (as nitrogen), which is the state of Florida drinking water standard.

Primarily because this option requires a significant amount of land area, it would not be applicable for the existing CAWWTP and SAWWTP. However, this may be a good disposal option for excess wastewater effluent and excess reclaimed water produced at the new East WWTP.

5.4.4

Shallow Aquifer Recharge Injection Wells

Reclaimed water can be disposed of by injection into a confined aquifer through shallow injection wells. The effluent must be treated to potable water quality standards, as required by FDEP, because this water is discharged directly into an aquifer without the benefit of any soil treatment. The distance between injection wells and groundwater extraction wells must be maximized to increase the detention time of the injected water underground and to allow mixing with natural groundwater. All injection projects shall comply with the technical and permitting requirements included in Chapter 62-528, F.A.C. The injection of reclaimed water into underground aquifers is a rarely used alternative. Direct injection of reclaimed water exhibits a high risk for contamination of the drinking water aquifer.

In addition, the cost associated with this alternative is

substantial due to the additional treatment needed to treat the water to potable water quality standards. Also, due to the high risk involved for contamination of the aquifer, the permitting process tends to be a lengthy and costly procedure. The implementation of injection wells, particularly any proposed expansions or new wells are heavily discouraged by the FDEP and face increased regulatory consideration.

5.4.5

Deep Injection Wells

Deep well injection is a common disposal method that is feasible from both a regulatory and technical standpoint as long as certain subsurface conditions exist. A highly permeable injection zone must be present so that large quantities of effluent can be disposed of at reasonable injection pressures. The injection zone must also contain saltwater with a total dissolved solids content in excess of 10,000 mg/L, which is City of Fort Myers Reclaimed Water Master Plan Section 5: Future Reclaimed Water Supply and Demand

Malcolm Pirnie, Inc. 5-14

classified as the upper limit for an underground drinking water source. Finally, the injection zone must be underneath confining beds having low vertical permeability to avoid migration of the injected fluids upward into drinking water aquifers.

These injection wells are utilized for wastewater disposal into deep saline aquifers during wet weather periods, when the reclaimed water demand for irrigation is low.

Permitting a deep injection well requires an extensive investigation into the regional and local geology and hydrogeology, and the development of a well design and testing program.

5.4.6

Aquifer Storage and Recovery (ASR)

Groundwater aquifers can provide a means of storage and recovery for reclaimed water. ASR of reclaimed water involves injection into a subsurface formation for storage and recovery at a later date. ASR is especially useful, because large quantities can be stored during low irrigation demand periods, and recovered during seasonal high demand irrigation periods, eliminating the need for large surface storage facilities. The amount of reclaimed water that can be stored and withdrawn from each ASR well is limited by aquifer characteristics. Several wells may be necessary to achieve the desired storage capacity.

The water recovered from the aquifer storage and recovery system must meet the CBOD5, TSS, and fecal coliform limits established for reuse as per Chapter 62-610, FAC. If the limits are not achieved, the FDEP will require that additional treatment or disinfection facilities be provided to ensure compliance with these limits. The City has experienced problems with meeting these standards at their Potable Water ASR well at the Winkler Pump Station.

Extensive water quality monitoring programs must be implemented to assure the recharged reclaimed water does not affect the quality of adjacent groundwater. Chapter 62-610, FAC provides details on implementation and monitoring programs for ASR sites in Florida. The potential also exists for incomplete recovery of the injected water.

Although very few reclaimed ASR facilities have been permitted in Florida, the study of ASR for reclaimed storage in Florida is increasing.

Hillsborough County

implemented the stateâ&#x20AC;&#x2122;s first reclaimed water ASR system at their Northwest facility in City of Fort Myers Reclaimed Water Master Plan Section 5: Future Reclaimed Water Supply and Demand

Malcolm Pirnie, Inc. 5-15

July 2001. This system is not currently operational due to problems with THM’s and arsenic. Several other reclaimed water ASR projects are being developed and are completing the DEP’s permitting process. These include projects in Sarasota County, Manatee County, St. Petersburg, Collier County, and the Englewood Water District. In 2002, the Englewood Water District became the second utility to initiate cycle testing of a reclaimed water ASR system.

Limited ASR storage could be implemented at the CAWWTP and SAWWTP, however implementing reclaimed water ASR wells in populated areas has been especially difficult. This could also be used at an offsite location that has less perceived potential for contamination of drinking water wells. Additional discussion of other possible ASR locations is discussed in Section 5.4.6.

5.4.6

Discharge through Regional Interconnections

The City could dispose of excess reclaimed water through interconnections with Lehigh Acres, Gateway, and the City of Cape Coral. The SFWMD has developed a plan identified as the Regional Interconnection and Distribution System (RIDS) for the Lower West Coast Region (Lee and Collier Counties) with the objective to meet the projected irrigation demand associated with future growth.

The City is required by their

Consumptive Use Permit to participate in the SFWMD RIDS program. The SFWMD recommends use of the RIDS, stating that it would: • • • • •

Optimize existing reclaimed water supplies Maximize seasonally available surface waters Diversify supply sources, potentially reduce water shortage declarations Offset potable water usage for irrigation purposes reduce wastewater disposal volumes Offset future potential groundwater withdrawals

This SFWMD study assumed that all future wastewater flows would be available for use as reclaimed water. The goal of the RIDS is to have 100 percent utilization of the effluent water in order to offset the irrigation demand during the dry season. The RIDS plans to utilize reclaimed water interconnects, allowing water to be shared between utilities. Also, ASR systems, recharged with reclaimed water during the wet season, could provide a source of irrigation water supply during the dry season.

City of Fort Myers Reclaimed Water Master Plan Section 5: Future Reclaimed Water Supply and Demand

Malcolm Pirnie, Inc. 5-16

A potential reclaimed water ASR site was identified within the City that would serve Fort Myers, Gateway, and Lehigh Acres. The site consists of 12 wells and a pumping station and would allow for 9 mgd of reclaimed water to be stored for use during the dry season. Figure 5.2 shows the proposed reclaimed water ASR site.

The RIDS also suggests possible interconnect locations that would allow water to be shared between the Central and South plants, and the towns of Fort Myers South, Lehigh Acres, and Gateway. A second interconnect was proposed to serve Fort Myers South, Fiesta Village, and the Gulf Environmental Services system.

These

interconnection locations are also shown on Figure 5.2. If the City chooses, excess reclaimed water not used within the City’s service area can be discharged into the regional system through these interconnects.

The City can implement recommendations made in the RIDS report to assist with storage and disposal of excess reclaimed water. The following benefits were published in the RIDS report: • • • • •

Meet increasing demands Allow reclaimed water to be shared between utilities for beneficial reuse Reduce reliance on surface water discharge Allow expansion of reclaimed water systems and infrastructure Utilize and/or store close to 100 percent of the reclaimed water in the region on an annual basis

6.0 MODEL EVALUATION OF FUTURE DISTRIBUTION SYSTEM The future distribution system was modeled for 5-year and 20-year future scenarios. The model analysis was similar to the model analysis of existing system presented in Section 4. The model was completed for a one week duration using the future supply and maximum user demands listed in Section 5. The future model was constructed to supply all of the identified future reclaimed water users at their peak demands. Piping was also included to connect the reclaimed water production facilities at the CAWWTP and the SAWWTP, for the 5-year model, and the East WWTP, for the 20-year model. All existing pressurized pipes that are transmitting water to the City’s seven existing reclaimed customers were included in the model. These evaluations include a comparison of peak flow showing the following for the future 2009 and 2024 scenarios: • • • • • • •

MODEL PERFORMANCE CRITERIA The City has already determined that the future production capacities will be 6.0

mgd at the CRWPF and 9.0 mgd at the SRWPF. The future models will include 9 MG of reclaimed storage at the SRWPF, while the CRWPF will be limited to 1 MG due to space constraints. An additional 8.0 mgd reclaimed production facility was added for the 2024 Model at a location just south of the LCRRF. Table 6.1 summarizes the model criteria used to build and evaluate the future 2009 and 2024 Models.

Piping Required for the 2009 Model

Many existing and new pipelines will be needed to connect the SAWWTP and CAWWTP and to supply reclaimed water to each of the existing and future customers.

The City has several existing reclaimed pipelines that are not currently being used.

Figure 6.1 shows the 2009 Model piping, and differentiates between the piping has already been installed and the new piping that will be needed by 2009. Table 6.2 lists the pipes that have already been installed that were not use in the Existing Model, (because they are not currently in used for reclaimed water distribution) but will be used for the 2009 Model.

Potential 2009 Interconnection Location

For the purposes of the Model, an interconnection was included at the north end of the Gateway Development for the 2009 Model. A 12-inch diameter transmission main was routed to the interconnection location (City limit/Gateway border) from Treeline Avenue at the north end of the Arborwood Development. This interconnection location was discussed previously and identified by the SFWMD as a RIDS recommended interconnection site. The interconnection was modeled to discharge into a storage tank, while maintaining an upstream pressure of 40 psi. A total of 9.5 MG of reclaimed water for the 7-day model duration was able to discharge to Gateway.

Potential 2024 Interconnection Locations

The 2024 Model included an interconnection with the City of Cape Coral. For the purposes of the Model, the Cape Coral interconnection location is just south of the Midpoint Bridge, along McGregor Boulevard. A 20-inch diameter main was routed from the SRWPF to the interconnection location at Colonial Boulevard and McGregor Boulevard. The interconnection was modeled so that reclaimed water could discharge to a storage tank, while maintaining an upstream pressure of 40 psi. A total of 3.3 MG of reclaimed water for the 7-day model duration was able to discharge through the Gateway Interconnection, and 11.0 MG to the Cape Coral Interconnection and 7.0 MG to the Lehigh Interconnection.

7.0 COST ESTIMATE FOR FUTURE IMPROVEMENTS This section discusses the costs associated with the future reclaimed water production and distribution infrastructure improvements. The costs are summarized for the 5-year and 20-year future dates by the following categories: • • •

Production Improvements Interconnections Distribution Piping

Additional discussion is included on the potential revenue from the sale of the reclaimed water to customers and to adjacent municipalities through interconnections.

Information is also included on the methods that the City can utilize to fund the recommended improvements.

7.1

BASIS OF COSTS The costs provided in this Master Plan are calculated in 2004 dollars. As this

Master Plan was being prepared, CDM was completing the planning and design for the expansion of the reclaimed water production improvements at the CAWWTP and the SAWWTP. The treatment plant upgrade costs calculated by CDM were incorporated into this Master Plan. The costs for the reclaimed water production portion of the new East Wastewater Treatment Plant are assumed to be similar to the upgrades at the CRWPF and SRWPF. The interconnection costs are calculated based on required length of pipe necessary to connect to the City’s system, and installation of a control valve and flow meter. Costs include a 10 percent engineering design fee and 20 percent contingency.

The distribution system piping costs are prepared by using $4.00 per inch diameter per foot length, with an additional $1.00 per inch diameter per foot for valves, hydrants, and bends and include a 10 percent engineering design fee and 20 percent contingency. All values are rounded up to the nearest $1,000.

Reclaimed water costs to users are calculated assuming the average annual demand will be half of the maximum projected demand. The assumed amount the City will charge for reclaimed water is $0.5748 per 1,000 gallons. This amount will be City of Fort Myers Reclaimed Water Master Plan Section 7: Cost Estimate for Future Improvements

Malcolm Pirnie, Inc. 7-1

compared to the amount the City charges for potable water, which is $3.03 per 1,000 gallons to determine the cost savings for reclaimed users.

7.2

5-YEAR IMPROVEMENTS The short-term recommended infrastructure improvements over the next 5 years

are estimated to be approximately $17.0 million for production improvements, $0.73 million for interconnection improvements, and $10.5 million for piping improvements, totaling approximately $28.23 million dollars.

The costs estimated for these

improvements are described below.

7.2.1

Production Improvements

The improvements at the CRWPF will include additional filter and chlorine contact capacity to produce 6.0 mgd of reclaimed water. Existing equipment can handle a maximum production of 2.0 mgd reclaimed water. Onsite storage will be limited to the existing 1.0 MG storage tank. Most of the pumps, piping, instrumentation and controls, and operations staffing at the CRWPF are already in place. Therefore the cost for upgrading the CRWPF will be approximately $5,000,000.

The construction of the SRWPF will include filtration and chlorine contact capacity, yard piping, control valves, instrumentation, 9 MG of storage capacity, and a minimum of 18 mgd high service distribution pumping capacity with variable frequency drives. The approximate cost for the SRWPF will be approximately $12,000,000.

7.2.2

Interconnections

The Gateway interconnection is included as a way for the City to share reclaimed water with the Gateway areas. The location was suggested by the SFWMD as part of their Regional Irrigation Distribution System Project. The total estimated cost for the Gateway interconnection is $1,454,600. The interconnection at Gateway will include a 12-inch transmission main from Treeline Avenue, a control valve, and a flow meter. The estimated costs for the Gateway interconnection and pump station are summarized in Table 7.1.

The costs for construction, operation, and

maintenance of this interconnection could be completed as a joint venture with Lee County and assuming that the County contributes 50 percent of the cost, the cost to the City will be approximately $728,000.

7.2.3

Distribution Piping

The costs for piping modifications to be completed by 2009 total $10,453,000.

These piping modifications are summarized below by service area in Table 7.2. The costs for the new pipelines in the Carrell Service Area are the highest. This area contains the majority of the 24-inch diameter main that will connect the CRWPF and SRWPF, and route reclaimed water to the South and Southeast Service Areas.

20-YEAR IMPROVEMENTS The long-term recommended infrastructure improvements for 2010 through 2024

are estimated to be $13.0 million for production improvements, $1.8 million for interconnection improvements, and $5.3 million for piping improvements, totaling $20.1 million. The costs estimated for these improvements are described below.

7.3.1

Production Improvements

The wastewater projections show that the City will need to build an East AWWTP with 8.0 mgd of by 2009. For the purpose of this report, we will assume that the costs for the reclaimed portion of the East AWWTP will be $13,000,000. A more detailed cost estimate for the new East AWWTP will be included in the Wastewater Master Plan.

7.3.2

Interconnections

The City could complete additional interconnections with the City of Cape Coral and Lehigh Acres. The total costs of the interconnections with Cape Coral and Lehigh Acres are estimated to be $3,400,000 and $128,500, respectively. Additional operational and maintenance costs for the Gateway interconnection will total $75,000.

The

calculated costs for the Cape Coral, Lehigh Acres, and Gateway interconnections for 2010 through 2024 are summarized in Table 7.3.

Malcolm Pirnie, Inc. 7-6

The costs for the Cape Coral interconnection will include a 16-inch diameter pipeline from the SRWPF and a 16-inch diameter pipeline across the river to Cape Coral.

The cost for directional drilling and for hanging the pipe from the Midpoint Bridge is estimated at $200 per foot. The Florida Department of Transportation would also have to approve the bridge installation.

Similar costs were estimated for a potable water

interconnection with the City of Cape Coral.

Assuming that construction will be

completed by 2014, costs for operation and maintenance will be included for ten years of use.

A control valve and flow meter could be provided for the Lehigh Acres interconnection at the Gateway location or on the property of the East AWWTP. Operation and maintenance for the Lehigh Acres interconnection is included for 14 years, assuming that connection would begin in 2011 when the East AWWTP is operational.

The Florida Governmental Utility Authority (FGUA) currently operates the Lehigh Acres wastewater system, however plans to turn over the Lehigh system to Lee County in the future. The exchange will most likely occur prior to the completion of the 20-year infrastructure improvements.

The costs for construction of the Lehigh Acres and Cape Coral interconnections, and the operation and maintenance of the Cape Coral, Lehigh Acres, and Gateway interconnections may be completed as a joint venture with the City of Cape Coral and the County. Assuming that each involved party contributes 50 percent of the respective interconnection cost, the cost to the City will be approximately $1,798,000.

7.3.3

Distribution Piping

The costs estimate for the long-term piping modifications to be completed from 2010 through 2024 is estimated to total $5,273,000. A summary of the costs calculated by service area are listed below in Table 7.4. The service area that will require the highest expenditure for reclaimed piping from 2010 through 2024 will be the East Service Area, while the South and Southeast service areas will not require additional reclaimed piping.

RECLAIMED REVENUE PROJECTION The City will recover some of the costs for implementing a reclaimed distribution

system by charging their customers for reclaimed water, and by sending water to adjacent municipalities through interconnections. The current reclaimed water billing rate is currently $0.5748 per 1,000 gallons. The revenue received from reclaimed users is calculated in Table 7.5, assuming the average annual reclaimed usage is equal to 50 percent of the maximum reclaimed usage.

Annual Revenue ($/year) $ 186,724 $ 656,680 $ 1,590,299

Malcolm Pirnie, Inc. 7-9

Assuming linear increases in revenue from reclaimed users between 2004 and 2009, the City should collect approximately $2.53 million in revenue for the sale of reclaimed water to City customers, and an additional $17.3 million will be collected between 2010 and 2024.

The projections of reclaimed production and customer demand show that there will be a large surplus of reclaimed water produced. The potential residential users identified as part of this report were limited to residential customers that are in new developments and in locations that already had some irrigation piping installed. These limitations were proposed to limit the capital cost and disruption of installing the piping to connect all potential users within the City. If other individual users were allowed to connect to the reclaimed distribution system, additional reclaimed water could be distributed and more revenue could be obtained. The City could also derive revenue from use of the interconnections with the reclaimed systems of adjacent municipalities.

Interconnections were included in the model, Gateway planned for 2009 and the Cape Coral and Lehigh Acres planned for 2024. The City should also consider providing interconnections to the County Areas which are served by the Cityâ&#x20AC;&#x2122;s Wastewater Treatment Plants. Table 7.6 below lists the potential additional revenue assuming maximum production availability.

It is unlikely that the available flows will actually be utilized by the adjacent municipalities through the interconnections. The amount of reclaimed water that can be distributed through these interconnections will be limited by hydraulic restrictions and by the actual reclaimed water demands in Cape Coral, and Gateway.

7.5

COST SAVINGS ATTRIBUTED TO THE USE OF RECLAIMED WATER The implementation of a reclaimed distribution system will save reclaimed

customers approximately 81 percent as compared to the cost of irrigation using potable water. The total savings estimated for reclaimed customers, using reclaimed water rather than potable water, is estimated to be approximately $2.8 million per year in 2009 and $6.8 million per year in 2024. The City will achieve an annual savings of approximately $700,000 per year by the year 2024 by implementing reclaimed water at their parks, golf courses, and roadway beautification projects.

7.6

FUNDING SOURCES The estimated $19.8 million of revenue from reclaimed water customers collected

over the next 20 years will not recover the $48.3 million in costs of the infrastructure improvements recommended in this report. The city will need to raise reclaimed rates to cover the cost of the improvements, or will need to investigate other methods of funding.

The City has historically used several alternate funding methods to pay for the infrastructure required to construct the existing reclaimed system, including State Revolving Funds, grants, and inter-local agreements for joint funding with Lee County.

This assumes that Lehigh Acres, Lee County and The City of Cape Coral would also help with the costs to construct interconnection pump stations. The City could have residential developers complete the installation of some reclaimed transmission mains in return for reduced taxes until the cost of the mains are reimbursed.

7.6.1 FDEP State Revolving Fund Loan Program The Water Pollution Control State Revolving Fund (SRF) Program provides lowinterest loans for planning, designing, and constructing water pollution control facilities.

The SRF Priority List schedules projects to be financed with loans from the SRF. It is developed annually and adopted by the Department under the provisions of Chapter 62503 of the Florida Administrative Code.

Projects eligible for SRF loans include

wastewater management facilities, reclaimed wastewater reuse facilities, storm water management facilities, and various other widely accepted pollution control activities.

SRF funds are made available for preconstruction loans and construction loans.

The SRF loan provides a 40-percent discount off of the 20-year bond rates at a lowinterest rate (currently equals 3.0 percent). The SRF also includes authorization of additional funds to projects already on the list and adding new projects to the list.

Utilization of SRF funds represents the lowest-cost opportunity available to finance City improvements. Repayment of the loan can be done so using the net operating revenues of the Water and Wastewater Utilities.

The City of Fort Myers is currently listed on the SRF Priority List to receive funding for the 2005 Fiscal Year (FY) for Phase IV and Segment 2 in the Downtown area of the Cityâ&#x20AC;&#x2122;s sewer rehabilitation and replacement program. Treatment and reuse facility improvements at the Central and South AWWTPs, as well as Phase IV and Segment 1 of the Downtown sewer rehabilitation and replacement program were awarded funding from the SRF for FY 2004.

7.6.2

SFWMD Alternative Water Supply (AWS) Grant Program

Section 373.1961(2) of the Florida Statutes encourages governing boards of the water management districts to include funding for the development of alternative water supply systems in their annual budgets. To be eligible for the SFWMD AWS Funding Program, projects must propose the development of capital facilities for effective and appropriate alternative water supplies. In FY 2004, the SFWMD received 42 requests for funding in response to the AWS Funding Program application process. The City was approved as one of 34 proposals that received funding. Funding for expansion of the CRWPF from 2 mgd to 6 mgd was received in the amount of $200,000.

7.6.3

Funding Strategy

The City currently is, and previously has, received financial assistance from both the FDEP State Revolving Fund and the SFWMD Alternate Water Supply Program for water and wastewater improvements. Based on the Cityâ&#x20AC;&#x2122;s familiarity and track record with the FDEP and SFWMD finding sources, it is recommended that these two sources be used for funding of the future reclaimed water infrastructure improvements if possible.

The alternative would be to raise the rates for reclaimed water.

The costs for the interconnection pump stations should be split with the municipalities that will be sharing the reclaimed water. Lehigh Acres and Gateway (Lee County) should be able to contribute to the cost of the Gateway interconnection and pump station. Lee County may also be sending wastewater flow to the East WWTP and, therefore, be sharing the expense for the funding of the new plant. The City of Cape Coral has a widespread reuse system, and is already running out of water to serve their customer demands. They may be eager to explore the possibility of an interconnection to supplement their existing supply.

SFWMD is requiring the City to participate in the interconnections as per conditions in their water use permit, and therefore should be willing to provide grant funding in addition.

Additional funding can be secured from State and Federal grant

funds, such as the Governorâ&#x20AC;&#x2122;s Program (formerly the WAP Grant Program) and the EPA State and Tribal Assistance Grants, respectively. These grants will provide funding, generally in lower quantities, but will assist to negate the use of borrowed funds if possible.

Many of the large new residential developments that are being planned and constructed are eager to have reclaimed water connected for their irrigation use. The City is currently negotiating with the developers to pay for all or part of the transmission main costs. The developers would then be reimbursed by having lower taxes until the cost of the transmission mains are reimbursed.

8.0 SUMMARY OF CONCLUSIONS AND RECOMMENDATIONS This section summarizes the conclusions and recommendations for this Reclaimed Water Master Plan.

The projected flows and future planned production upgrades at the

CRWPF, future SRWPF, and new East RWPF are discussed. Recommendations for major distribution system piping and installation are summarized.

The findings,

conclusions, and final recommendations of this Reclaimed Master Plan are presented below.

8.1

FINDINGS AND CONCLUSIONS The findings and conclusions of this Reclaimed Water Master plan have been

determined from studying all of the available data from the City on the reclaimed water production and distribution system. This report has been reviewed in depth by City staff for accuracy and correctness of all dates, times, and projection assumptions.

8.1.1 Existing Reclaimed Water System The City’s existing reclaimed water system currently serves seven customers.

Among the current users, the most common use for reclaimed water is for irrigation of public parks and landscaping. However, the largest user of reclaimed water is Lee County’s Resource Recovery Facility. Each of the existing users receives reclaimed water on an individual demand basis, with an annual average demand totaling approximately 0.79 mgd in 2003.

The LCRRF receives a continuous flow of reclaimed water each day of the year at much larger quantities than the other users. The City’s interlocal agreement with the County requires that reclaimed water be delivered to the LCRRF at a minimum pressure of 45 psi. This pressure requirement was assigned in the model as the minimum pressure for all areas of the distribution system.

The City achieves successful delivery of

reclaimed water to all customers as the demand exists.

City of Fort Myers Reclaimed Water Master Plan Section 8: Summary of Conclusions and Recommendations

Malcolm Pirnie, Inc. 8-1

Currently, reclaimed water production and distribution is limited by the amount of distribution system storage capacity. The CRWPF maintains a 1 MG ground storage reservoir for onsite storage, which satisfies the City’s current reclaimed water demand.

8.1.2

Regulatory Summary

The Central AWWTP reuse permit, developed and monitored by the FDEP, specifies the quantity and quality of effluent that can be used for reuse and land application. Plant staff must continuously monitor parameters such as CBOD5, TSS, pH, turbidity, and residual chlorine levels present in the effluent following disinfection to determine whether the effluent is of reclaimed water quality. A single sample maximum CBOD5 and suspended solids concentration of 60 mg/L and 5 mg/L, respectively, a total residual chlorine concentration of at least 1 mg/L, and a pH value within the range of 6.5 to 8.5 constitutes effluent in compliance with reclaimed water standards.

Monthly Discharge Monitoring Reports and annual Effluent Analysis Reports are submitted to the FDEP to verify that the wastewater facilities are meeting reclaimed water and surface water discharge limitations and are not impacting ground water or surface water quality. The CAWWTP, SAWWTP, and the CRWPF historically have been in compliance with all applicable regulations and the reclaimed water provided to the City’s existing users is sufficient for the intended uses.

Growth of the City’s

reclaimed water distribution system will allow the City to decrease their dependence on effluent discharge to the Caloosahatchee River, which will soon be required as a result of recent TMDL legislation passed in Florida.

The City is currently permitted to provide reclaimed water to customers for irrigation of landscaped areas and for use in industrial applications. As discussed in this Master Plan, many of the future planned users will be residential developments. Upon expansion of the system and the addition of new users, it will be necessary for the City to modify their existing FDEP permit to allow for irrigation of residential areas (by the individual homeowner). The permit may include special conditions for those residential developments to be newly constructed. The City may chose to provide only a set volume of reclaimed water, requiring the customer to provide storage and repumping capabilities as necessary to meet the desired pressure needs.

City of Fort Myers Reclaimed Water Master Plan Section 8: Summary of Conclusions and Recommendations

Malcolm Pirnie, Inc. 8-2

As the City begins to implement a more regional-type reclaimed water distribution system, the Cityâ&#x20AC;&#x2122;s Code of Ordinances must be revised to address numerous regulated design conditions and public health concerns. Additional standards must be included for the presence of double check valves or reduced pressure backflow prevention devices at locations with the high risk for cross connections with the potable water system. A routine schedule for inspection of these reclaimed water services should be maintained to assure that cross connections are avoided. Enhanced inspection efforts will be required in order for residential or small commercial reclaimed water users to become part of the Cityâ&#x20AC;&#x2122;s service, as per the FDEP requirements in FAC 62-610.470 and 62-555.360.

Public awareness and education efforts must also be implemented to increase public understanding of reclaimed water. Through public awareness programs, the City can promote water conservation through the use of reclaimed water, attracting additional communities and industries to connect to the reclaimed water system. Advantages such as a reduced demand on drinking water sources, a cost-efficient supply of water, and the reliability of a continuous supply of water for irrigation of lawns, parks, and golf courses will provide the public with a positive view of reclaimed water.

Identification of

reclaimed water distribution system piping and equipment, through the use of colored pipe and appropriate signage, is required in order to raise awareness and assure that the public understands the water is not for human consumption.

8.1.3

Historic and Projected Reclaimed Water Demands

The historic reclaimed water demand, from the existing seven users, is approximately 0.717 mgd, with a maximum demand of 1.155 mgd observed during the maximum month of reclaimed water usage. Research into both existing sites and future developments that could potentially use reclaimed water, for the purpose of quantifying existing and projected water demand, resulted in identification of 66 additional future reclaimed water customers. The majority of the future users consist of golf courses, existing and new residential developments, and City parks, with only one industrial and ten commercial irrigation customers. The total potential reclaimed water demand from

City of Fort Myers Reclaimed Water Master Plan Section 8: Summary of Conclusions and Recommendations

Malcolm Pirnie, Inc. 8-3

the 73 identified future users is estimated to be 6.26 mgd and 15.15 mgd for 2009 and 2024, respectively.

The City has already made the commitment to complete expansion of 6.0 mgd and 9.0 mgd reclaimed water production capacity, respectively, at their Central and South AWWTPs. The minimum three-month average wastewater flow should remain less than these values to remain in compliance with their future water use and wastewater treatment permits.

The three-month rolling average flow was calculated for each day based on the flows recorded for the previous 90-day period.

The minimum three-month rolling

average for the calendar year was determined as the day during that year with the minimum calculated rolling average. The historical and projected minimum three-month rolling average flows for each plant are listed in Table 8.1. Historical minimum threemonth average daily flows have been as high as 83% of average annual flow at the CAWWTP and 90% at the SAWWTP.

A second method was used to determine the Central and South AWWTPs ability to meet future treatment capacity needs. Table 8.2 shows the historical and projected â&#x20AC;&#x153;lowestâ&#x20AC;? three month average flows, calculated by averaging the three months during the calendar year when the monthly average flow is the lowest. This calculation method differs from that shown in Table 8.1 in that the lowest three months are not required to be City of Fort Myers Reclaimed Water Master Plan Section 8: Summary of Conclusions and Recommendations

consecutive. Historical values for the average of the lowest three months of flow have been as high as 82% of average annual flow at the CAWWTP and 88% at the SAWWTP.

Both methods of calculating the three-month average flows (Table 8.1 and Table 8.2) for the CAWWTP and SAWWTP provided comparable results. In both analyses, the projected minimum three-month average flows for the CAWWTP are higher than the 6.0 mgd reclaimed water capacity that is planned at the CAWWTP for 2009 and 2024. The future flows will depend on where the wastewater flows in the eastern collection area are conveyed. These projections assume that 1.07 mgd 1.43 mgd are conveyed to the County’s Gateway WWTP in the years 2009 and 2024, respectively. The remaining flows from the east are split 50% to CAWWTP and 50% to SAWWTP for 2009, and 100% to the new East WWTP in 2024).

8.1.4

Operational Control

The current operational protocol automatically rejects reclaimed water before it is pumped to storage if the pH is not between 6.5 and 8.5, the chlorine residual is less than 1.0 mg/l, or if the turbidity is greater than 5 mg/L. The pumps are equipped with variable frequency drives that vary flow but maintain a constant pressure of 62 psi for flow from the CRWPF.

City of Fort Myers Reclaimed Water Master Plan Section 8: Summary of Conclusions and Recommendations

Malcolm Pirnie, Inc. 8-5

The capacity at the CRWPF will increase to 6 mgd, but the storage will still be limited to 1MG. To effectively operate with this limited storage volume, the production facility should continuously vary the flow being treated based on the water level in the ground storage reservoir. This requires the filtration and chlorine contact equipment to be sufficiently sized to meet the peak demands of the reclaimed water customers, rather than being limited to a maximum flow rate of 6.0 mgd.

The SRWPF will have enough space to install one days worth of reclaimed water storage for the design capacity of 9.0 mgd. This will provide a more reliable source of reclaimed water supply. Therefore, when the SRWPF is online, it should assume the role of pressurizing the distribution system, allowing the pumps at the CRWPF to reduce flows when the level in the 1 MG ground storage reservoir is low.

The majority of the effluent of the East WWTP will need to be disposed of via distribution to reclaimed water customers and through interconnections with adjacent utilities. When the East RWPF is online, the distribution system pressurization from the SRWPF may need to be reduced to maximize the use of reclaimed water from the East RWPF.

8.1.5

Reliability of Reclaimed Water Supply

The Cityâ&#x20AC;&#x2122;s two existing wastewater treatment plants will soon have the capability to produce a combined 15 mgd of reclaimed water available for distribution. This will be sufficient to handle the estimated maximum 6.26 mgd (weekly average) demand for 2009. With the addition of a third new East WWTP, an additional 8 mgd of treatment capacity will be available to meet the estimated maximum 15.15 mgd (weekly average)reclaimed demand for 2024. The presence of three reclaimed water production facilities will provide a reliable and redundant source of reclaimed water and ensure a sufficient supply to all customers. This reliability will be enhanced by the construction of bi-directional flow capability at the proposed interconnection locations with the City of Cape Coral, Lehigh Acres and Gateway.

8.1.6

Costs and Revenues associated with Future Reclaimed Water Improvements

The short-term recommended infrastructure improvements over the next 5 years are estimated to be approximately $17.0 million for production improvements, $0.73 million for interconnection improvements, and $10.5 million for piping improvements, totaling approximately $28.23 million dollars.

The long-term recommended infrastructure improvements for 2010 through 2024 are estimated to be $13.0 million for production improvements, $5.3 million for interconnection improvements, and $1.8 million for piping improvements, totaling $20.1 million.

The estimated revenue from reclaimed water customers collected over the next 20 years is $19.8 million. Additional revenue could also be obtained from selling reclaimed water to adjacent municipalities through the proposed interconnections.

To make up the difference in the costs for the infrastructure and the revenues collected, the City could raise the rate for reclaimed water use, or could utilize other funding methods.

These methods include State Revolving Funds, grants, and joint

funding with Lee County, Cape Coral and Lehigh Acres. The City has historically used State Revolving Funds, grants and assistance from Lee County to pay for the infrastructure required to construct the existing reclaimed system. The City could also have residential developers complete the installation of some reclaimed transmission mains in return for reduced taxes until the cost of the mains are reimbursed.

8.2

RECOMMENDATIONS 8.2.1 Future Planning Initiatives Future expansion of the reclaimed water system, production, and distribution will

require construction of additional offsite storage facilities to accommodate peak demands on the system.

Malcolm Pirnie recommends that the City pursue the following

initiatives. 他

Encourage reclaimed water for new developments The City should implement the use of reclaimed water for irrigation of newly constructed residential communities. This allows for reclaimed water pipelines to be laid at the time of building construction, eliminating the burden

City of Fort Myers Reclaimed Water Master Plan Section 8: Summary of Conclusions and Recommendations

Malcolm Pirnie, Inc. 8-7

of potentially costly infrastructure repair that would be required for connection of existing developments to the reclaimed water system.

Connection of new residential developments to the City’s system would provide a reclaimed water demand of approximately 8.0 mgd by 2024 for the City. Conveyance of the reclaimed water to each individual development can be contracted so that the City must only provide a given volume of reclaimed water, requiring the developer to provide storage and pumping capabilities as necessary to meet the desired pressure needs. ¾

Implement reclaimed water irrigation at select City parks Irrigation of City parks using reclaimed water should be implemented. A total of 20 City parks were originally identified as future reclaimed water users.

Further evaluation of the 20 parks with respect to ease of connection to the City’s system, and individual reclaimed water demand (based on irrigable acreage) resulted in 14 parks where irrigation with reclaimed water would be economical to the City. These select City parks are shown in Table 8.2.

Irrigation of these areas using reclaimed water would be feasible for the City to implement and would offer a substantial savings to the City over potable water usage.

Require storage at user locations to reduce peak demands In order to dampen the peak demands on the system, the City should require each individual user with demands greater than 100,000 gpd to maintain onsite storage. This will also lessen the burden on the City to meet the desired pressure needs within the distribution system.

City of Fort Myers Reclaimed Water Master Plan Section 8: Summary of Conclusions and Recommendations

Malcolm Pirnie, Inc. 8-8

¾

As the reuse system in implemented, seek to reduce discharge of effluent to the Caloosahatchee River from the CAWWTP and SAWWTP The CAWWTP and SAWWTP should be able to continue to dispose of their effluent through surface water discharge to the Caloosahatchee River; however, the potential exists for a future reduction in discharge capacity. The FDEP is currently in the process of developing and implementing TMDLs for the Caloosahatchee River. By 2006, guidelines will be published and water quality standards will be established within each facility’s discharge permit.

In addition to the FDEP guidelines, the City’s Consumptive Use Permit will soon require the City to utilize 100-percent of the reclaimed water produced.

This will allow the City to reduce their dependence on River discharge.

However, the use of the River discharge will serve as adequate disposal capacity for wet weather disposal of excess reclaimed water.

¾

Expedite Reclaimed Storage and Pumping facilities at the East AWWTP Location.

The City may chose to expedite the construction of the reclaimed water storage and pumping capacity that will need to be constructed for the East AWWTP. Since the storage capacity at the CRWPF is limited, this would provide an offsite location for reclaimed water storage. A pumping facility at this location will also help to maintain the pressure requirement of 45 psi at the LCRRF. This storage and pumping facility could be designed along with the upgrades of the CRWPF and the new SRWPF, and could be online by 2009. However, the updated wastewater flow projections show that the entire new East AWWTP will need to be online by 2009.

¾

Install RIBs or deepwell injection at East AWWTP for disposal of excess Production of reclaimed water at the East WWTP, during certain months of the year, may exceed the reclaimed water user demand at that time. Also, the reclaimed water production quantity may not equal the amount of treated wastewater effluent available. Therefore, storage and disposal of excess wastewater effluent and excess reclaimed water at the East WWTP may be necessary. The use of rapid infiltration basins or deep injection wells, as discussed in Section 5.4, is a viable option that will provide the City with a means to dispose of their effluent at the East AWWTP. A large amount of land area is necessary for implementation of the infiltration basins and therefore the City could investigate available land in the East Service Area. If adequate land is not available, the City may consider deep well injection.

¾

Explore the opportunity to construct Interconnections Interconnections between the City’s reclaimed water distribution system, the Gateway Development, and City of Cape Coral are recommended as part of

City of Fort Myers Reclaimed Water Master Plan Section 8: Summary of Conclusions and Recommendations

Malcolm Pirnie, Inc. 8-9

this Master Plan. The interconnections can be used to provide regional sharing of reclaimed water, and to provide the City with storage and pumping capacity. These interconnection locations can provide the City with additional reclaimed water if needed, and will provide revenue for excess reclaimed water that is not needed by City residents.

8.2.5

Future Infrastructure Requirements

Production Capacity The 9.0 mgd SRWPF at the 12.0 mgd AADF SAWWTP should provide adequate treatment capacity to meet the requirement that the City provide treatment for the lowest three month rolling average flow. However the projected flows show that the 6.0 mgd CRWPF will not provide the capacity to meet the lowest three month rolling average flows at the CAWWTP. This facility may need to be increased in size to 7.5 mgd, or more of the flows could be diverted to the new East WWTP in the future. The production at the Central and South reclaimed water facilities will be limited by the amount of demand present in the system, therefore expansion of the production facility to a capacity higher than 6.0 mgd may not be necessary, other than for regulatory requirements, if there is not sufficient demand to support the capacity.

Several residential developments are already requesting reclaimed water. The approval of additional users will need to be rationed until additional capacity is available, in order to maintain the flows for the contract with the LCRRF.

Reclaimed Water System Storage The City should ideally have one days worth of storage onsite at the Reclaimed Water Production Facilities to handle the demand fluctuations that will occur during the day without having the tanks run dry. This will be possible at the SRWPF and East RWPF, but not the CRWPF. If all of the storage is installed as recommended in this report, a total of 18 MG will be available if there is 1 MG at the CRWPF, 9MG at the SRWPF, and 8 MG at the East RWPF. The majority of the Cityâ&#x20AC;&#x2122;s future users will require water for irrigation purposes during various hours of the day/week. The City should recommend that all users with demands greater than 100,000 gpd should have one days worth of storage onsite. The users could use tanks or ponds for storage of reclaimed water.

City of Fort Myers Reclaimed Water Master Plan Section 8: Summary of Conclusions and Recommendations

Malcolm Pirnie, Inc. 8-10

Piping Requirements All of the piping listed in Section 6 is recommended to serve future users. The pipe routes were chosen based on the path of least resistance.

The routing of the

pipelines can be changed as long as the users are still receiving reclaimed water. City staff will be trained to modify the piping in the model to evaluate many possible routing scenarios. The pipeline projects should be completed in conjunction with the remaining Water Main Replacement Project phases, if possible.

The mains that are listed as 6-inch and 4-inch diameter mains should be increased in size if individual residential users may be served in the future. The addition of reclaimed water service to existing single connection residential users was avoided by request of City staff. The installation of service connections to individual users would cause disruption to neighborhoods and existing roadways, and would require backflow prevention devices to be installed on all of the potable connections to the users. The existing individual users in Heritage Palms, Dean Park, and West McGregor were included as possible future users because they already have some irrigation lines installed and could be served with reclaimed water with minimal piping connection modifications.

Chapter 26 PUBLIC FACILITIES* *Cross references: Procedure for conveyance of city property, § 2-29; code enforcement procedures, § 2-156 et seq.

ARTICLE V. RECLAIMED WATER PROGRAM* *Cross references: Extension of the reclaimed water use service, § 18-100 et seq.; utilities, Ch. 18.

Sec. 26-201. Purposes.

The purposes of this article are: (1) (2) (3) (4) (5)

To establish that the public works department shall prepare a master plan for reclaimed water service and keep it current.

To establish procedures and policy for obtaining reclaimed water service within and adjacent to the city.

To provide for fees and charges.

To establish requirements for construction of reclaimed water systems.

To establish procedures for commitments for service.

(Code 1963, § 39-52; GMC § .010(E)(1))

Sec. 26-202. Administration.

This article shall be administered by the city public works administrator through the public works department.

The administrator is responsible for the development and promulgation of rules and regulations that will be needed to assist the public to work within these policies.

(Code 1963, § 39-53; GMC § .010(E)(2))

Sec. 26-203. Jurisdiction.

Unless otherwise provided herein, this article shall apply to the areas of the city which are within formally established service areas.

(Code 1963, § 39-54; GMC § .010(E)(3))

Sec. 26-204. Source of reclaimed water. (a)

(b) (c)

To reduce demands on the city's potable water supply facilities, the city plans to supply reclaimed water to customers through a separate reclaimed water distribution system to satisfy water demands that do not require the use of potable water. This reclaimed water will consist of treated, filtered and chlorinated effluent from wastewater treatment plants.

When alternative sources are available to the reclaimed water supply system, the reclaimed water supply shall be given first priority.

Sources of reclaimed water shall comply with the following state department of environmental regulations as they may apply and as they may be revised from time to time.

Sec. 26-205. Use and distribution of reclaimed water. (a)

The city shall develop and maintain a reclaimed water master plan. Such plan shall receive city council approval and shall include: (1) Designated areas of the city within which construction and use of a reclaimed water system shall be encouraged.

(2) The suggested general location of a pipeline transmission system as a basis of supply for a local reclaimed water distribution system.

(b)

Use of reclaimed water is intended to limit potable water requirements within a residential development to that used in swimming pools, household laundries, kitchens, bathroom tubs, showers and lavatories. Use of water-saving devices on fixtures and a public attitude to avoid waste will result in a significant reduction in the use and consumption of potable water.

Use of reclaimed water may include any and/or all of the following: (1) Lawn, garden and landscaping irrigation.

(2) Irrigation of golf courses and other recreation areas.

(3) Industrial.

(c)

(d) (e) (f)

(g)

The use of reclaimed water may be separately metered for each connection, as is the case for potable water, and appropriate rates will be established by the city council for the use of reclaimed water.

The city plans to initially develop sources and supply reclaimed water to local distribution systems within the developments for irrigating lawns, gardens, trees, shrubbery, golf courses and open space in and adjacent to the city.

Commercial and industrial customers presently using potable water will be encouraged to use reclaimed water wherever such use is safe and practicable, not only for landscape irrigation but in processes not requiring the use of potable water. To assist commercial and industrial users in evaluating possible uses of reclaimed water, the city will provide appropriate reclaimed water quality analysis.

Within individual new development areas, a separate reclaimed water distribution system shall be installed in accordance with city engineering and construction standards when, in the opinion of the city, such installation is required to satisfy current planning for the distribution and use of reclaimed water. Costs for the installation of a nonpotable water distribution system shall be borne by the owner/developer. Applications for all new development shall include provisions for the use of reclaimed water.

ARTICLE X. CROSS-CONNECTION CONTROL STANDARDS Sec. 26-326. Purpose and intent.

It is necessary for the protection and promotion of the health, safety and welfare of the people, served by the city water system, to adopt cross-connection control standards which provide for protection of the city potable water supply; protect the potable water system at the service connection by isolating within the consumer's premises actual or potential pollution or contamination which may result from backflow or through cross-connection; segregate domestic and industrial uses into separate systems to prevent possible pollution or contamination of the private potable water system and provide a continuous program of crossconnection control which will systematically and effectively prevent the contamination of the city potable water system. Such standards supplement, but do not supersede or modify the Standard Plumbing Code as adopted for the City of Fort Myers, Florida.

(Ord. No. 2769, ยง 6, 12-4-95)

Sec. 26-327. Responsibilities.

The consumer shall have the prime responsibility of preventing contaminants and pollutants from entering the city's water supply system from their water supply system. The consumer shall protect their water supply system against actual or potential cross-connection, backflow or back-siphonage, as required by the Standard Plumbing Code and this article and other applicable regulations. They shall assure that all internal protective devices are tested and maintained in the working condition required. They shall assure the necessary plumbing permits are obtained for new water supply system installations, and for alterations or repair to existing systems in accordance with the locally adopted Standard Plumbing Code including Appendix D. (Ord. No. 2769, ยง 6, 12-4-95)

Sec. 26-328. Operational criteria.

When a hazard or potential hazard to the city water system is found on the consumer's premises, the consumer is required to install an approved backflow prevention device at each city water service connection to the premises in accordance with the requirements of this article. The type of device shall depend on the degree of hazard involved and shall be installed in accordance with "Backflow Prevention Devices (Illustrated)" and "Typical Installations (Illustrated)" attached hereto and made a part of this article.

(Ord. No. 2769, ยง 6, 12-4-95)

Sec. 26-329. Protective devices.

The type of protective device required shall depend upon the degree of hazard as described in AWWA Manual M-14 or as described below. Where more than one type of protection is possible, the actual method utilized shall be at the discretion of the city subsequent to physical inspection of the hazard.

(1)

In the case of any premises where there is an auxiliary water supply, there shall be no physical connection between such auxiliary water supply and the consumer's water system which is served by the city water supply system. Where such connections are found, disconnections shall be accomplished and the city water system shall be protected against the possibility of future reconnection by an approved reduced pressure principle backflow prevention device at the service connection.
