HDD and HDPE: The Perfect Match

ASTM F1962 – 22

Standard Guide for Use of Maxi-Horizontal Directional Drilling for Placement of Polyethylene Pipe or Conduit Under Obstacles, Including River Crossing 2022 Issue Now Available (Includes PE4710 Material) For Water and Other Applications

ASTM F1962, Standard Guide for Use of MaxiHorizontal Directional Drilling for Placement of Polyethylene Pipe or Conduit Under Obstacles, Including River Crossings, was originally approved in 1999, following development within the F17.67 Trenchless Technology Subcommittee of the ASTM1, and reissued in 2005 and 2011, and previously reinstated in 2020. The corresponding changes to the document, if any, were minimal, including providing additional or updated references, as well as correcting a typographical error in one of the equations. The most significant reference was to the alternative guidelines TR-46 provided by the Plastics Pipe Institute (which has been superseded by MAB-7 provided by its Municipal Advisory Board), as more appropriate for mini-HDD operations. However, the latest revision of ASTM F1962, approved in 2022, contains a significant change by providing the physical properties for the most recent high density polyethylene (HDPE) material,

PE4710. This material is significantly tougher than older, previously used PE products, facilitating successful completion of more complicated, difficult maxi-HDD projects. The allowable pulling loads are based upon a minimum tensile yield strength of 3,500 psi, with a significant reduction to limit non-recoverable viscoelastic deformation, as well as to account for the effective cumulative load duration on the pipe (assumed to be 12 hours), resulting in a safe pull stress of 1,330 psi.

Its convenient methodology for selecting an appropriate pipe strength (wall-thickness), based on the project characteristics, has led to its increasing popularity and widespread usage within industry. A description of ASTM F1962, and its application, was provided during industry events and conferences, including NO-DIG (Slavin and Petroff, 2010) and ASCE pipelines (Petroff, 2010) conferences in 2010. ASTM F1962 is the only available ASTM standard for horizontal directional drilling.

Overview

The ASTM document provides overall guidelines for a maxi-HDD operation (see Figure 1), addressing preliminary site investigation, safety and environmental considerations, regulations and damage prevention, bore path layout and design, implementation, and inspection and site cleanup. One of the most significant contributions of ASTM F1962 is the provision of a rational, analytical method for selecting the pipe strength based upon the estimated installation loads

Conference Lights Ahead…..And Future Water Sources for Texas

By the time you read this article, the Texas Water Conference will only be a few weeks away! No one is ever totally ready for the conference, but everyone is always happy to embark upon the special Texas city that traditionally welcomes over 3,000 guests to the largest regional water conference in the U.S. This year, we descend upon Houston, the largest city in Texas, and out of 28 Texas Water conferences, it’s only the third time we’ve celebrated it in Houston. The last time we did it in 2019, we smashed every record, only to be outdone by San Antonio last year—so Houston is ready to reclaim some of the exceptionalism it deserves.

At the time of this writing, 78.4% of Texans are experiencing some level of drought, which is updated every Thursday by the Texas Water Development Board. Some of us live in cities or towns where drought has immediate impacts on our daily lives. For example, the City of Corpus Christi has been in a Stage 1 Drought Restriction since June 15, 2022, while San Antonio, the largest city in Texas to be in some level of drought restriction is currently in Stage 2. Of the 7,000 public water systems across Texas, 474 are currently in some state of water restriction. Like many communities across the state, the City of Corpus Christi has worked diligently to develop and encourage water conservation programs, but unfortunately these programs have limitations. As supplies dwindle, the City is looking for drought-proof sources of water that can sustain our quality of life.

From a surface water supply standpoint, Corpus Christi has excelled by securing water from three river basins that include the Nueces, LavacaNavidad, and the Colorado. How many public water systems have three distinct and separate sources of surface water supply? I cannot think of any, but if you know of one, please let me know! The Colorado and LavacaNavidad River water is conveyed to Corpus Christi by pipeline at a distance of over 100 miles! The vision and perseverance of visionaries like Mayor Mary Rhodes in the late 1990s was tremendous—despite significant

Money, Money, Everywhere – Can I Get a Drink?

If you have been paying any attention to the news as the legislative session started, you undoubtedly have heard that Texas is projected to have $188.2 billion available in general revenue for funding the business of the state over the next two years. This is about 26% more than the state has ever had available for programs and according to State Comptroller Glenn Hegar, "The amount of projected revenues give the state a remarkable, a truly once-in-a-lifetime opportunity, for historic actions in this legislative session."

This extraordinary amount comes primarily from sales and energy taxes and the notes of caution are already being pushed forward so everyone realizes that it would be foolish to spend every dollar. However, even in the most conservative of groups, everyone is lining up to "encourage" the members of the legislature to direct dollars to a number of pressing needs.

The water community, including Texas AWWA along with a consortium of water associations and other interested groups, are working closely together to present a united front to address numerous water supply and infrastructure needs throughout the state.

The funding needs for water and wastewater infrastructure upgrades in Texas are significant. The Texas Water Development Board estimates that $53 billion will be needed for water infrastructure alone between 2020 and 2070. Funding for wastewater infrastructure is also needed on top of that, making it a huge financial burden for the state and communities.

The question is how to fund such a large investment. The traditional method of funding infrastructure upgrades is through government grants and loans. However, the federal government's funding for water and wastewater infrastructure has been decreasing in recent years, leaving states and local communities to shoulder a larger share of the financial burden. In

recent years, AWWA successfully worked with Congress to secure the Water Infrastructure Finance and Innovation ACT (WIFIA) and is currently working with other groups on the national level to maintain the funding levels of the State Revolving Fund (SRF). But these funding mechanisms are never enough. And, here in Texas, we do not have dedicated funding for water and wastewater infrastructure, making it difficult for communities to secure funding for upgrades.

One solution that has been proposed is the creation of a state water infrastructure bank. This type of bank would provide low-interest loans to communities for water and wastewater infrastructure upgrades. By providing low-interest loans, the bank would make it more affordable for communities to fund upgrades, while also reducing the burden on ratepayers. That is the direction we are hoping the legislature will commit to with a portion of the billions of surplus funds available this year.

There are other funding options, including increasing the use of private financing for water and wastewater infrastructure upgrades, but this raises concerns about potential rate increases and the privatization of water and wastewater services. Or, some periodically suggest increasing the use of publicprivate partnerships (PPPs) for water and wastewater infrastructure upgrades for certain projects. The difficulty in all these other options is that they don’t address the problems of smaller systems and could

EPA Announces $2B to Address Emerging Water Contaminants in Small, Disadvantaged Communities

On Feb. 13, the U.S. Environmental Protection Agency (EPA) announced $2 billion to address emerging contaminants in small and disadvantaged communities’ drinking water, including per- and poly- fluoroalkyl (PFAS).

EPA made the announcement as it continues to review comments on its proposed rule to designate PFAS as a hazardous substance under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), and as the Agency readies for release of a proposed rule establishing a national drinking water standard for PFAS "in the coming weeks."

The $2 billion in funding will be made available later this year through the new Emerging Contaminants in

Small or Disadvantaged Communities (EC-SDC) grant program. It is a result of the bipartisan Infrastructure Investments and Jobs Act (IIJA), which authorizes $5 billion between fiscal years 2022-2026 to "help communities that are on the frontlines of PFAS contamination reduce PFAS in drinking water." The new grant is fashioned to include disadvantaged communities in both rural and urban settings.

Eligible projects for EC-SDC, according to EPA, will include:

• Efforts to address emerging contaminants in drinking water that would benefit a small or disad-

on the polyethylene pipe. Thus, ASTM F1962 provides a means of determining project feasibility, as well as initial design information. Such results could be further refined by competent engineering expertise, including an analysis of pipe and soil characteristics and interaction, often including the use of relatively sophisticated software tools, possibly based on the ASTM F1962 methodology. The procedure is straightforward and has been incorporated into various software tools (e.g., PPI Boreaid®) as an engineering and design aid for such projects.

The ASTM standard specifically addresses polyethylene pipe (PE), a flexible product, for which the effects of any bending stiffness on drag forces at route bends or path curvature may be ignored. Relevant material properties

for PE pipe, such as safe pulling tension/stress, are also provided in the document. Because of its high ductility and flexibility and ability to be fused in continuous lengths, per the well-established ASTM

standards and by experienced contractors, polyethylene pipe, particularly high density polyethylene (HDPE), is the most commonly used product for HDD projects. Although ASTM F1962 is intended for carefully designed, well-controlled maxi-HDD installations, the methodology has been extended, via appropriate assumptions and mathematical simplifications, to provide a simpler methodology that may be advantageously applied to typical, less well-controlled mini-HDD projects. This is the basis of MAB-7 (2020), MAB Guidelines for Use of Mini-Horizontal Directional Drilling for Placement of HDPE (PE4710) Pipe in Municipal Applications, as referenced in the 2022 edition of ASTM F1962.

Description

Figure 2 illustrates a typical geometry for a maxi-HDD operation, in this case corresponding to a river crossing. The indicated bore/pipe path comprises three segments spanning the pipe entry (point A) to its exit

point (point D), with horizontal projected distance Lbore, equal to the sum of the three horizontal (projected) segments L2, L3 and L4. There is an additional length L1 exterior to the drilled path which allows for handling at both ends and possible other effects (path curvature, thermal contraction, stretching, etc.). The intermediate horizontal segment, L3, may be of zero length, similar to the geometry in Figure 1.

ASTM F1962 contains ten main chapters or sections, as briefly described below, supplemented by several appendices.

Scope, Referenced Documents and Terminology (Sections 1, 2 and 3)

ASTM F1962 addresses the overall planning and design, product selection and installation practices for the placement of polyethylene pipe using maxi-HDD equipment. The primary focus is on commonly used high density polyethylene (HDPE) pipe with a material designation code of PE4710. For the larger diameters typically used for such applications, the polyethylene pipe is supplied in discrete segments which are fused

together in the field, with essentially no loss in tensile strength, facilitating the pulling operation.

Preliminary Site Investigation (Section 4)

Both ends of the bore path, must be investigated to confirm their feasibility for successfully completing the installation of the large, long pipeline. The drill rig and auxiliary equipment located on the pipe exit side are relatively large, and require water access, storage and mixing and pumping facilities. The pipe entry side, opposite the drill rig, must accommodate the long length of assembled (fused) pipe. In addition, there should be a detailed subsurface investigation, including test borings and soil analysis, to confirm

the general suitability for the drilling operation, and to determine the appropriate equipment and hardware.

Safety and Environmental Considerations (Section 5)

Safety is a primary concern, during any activity, including construction utilizing maxi-HDD equipment and procedures. Potential safety issues fall into two general categories:

(1) those directly related to the setup and operation of the maxi-HDD equipment, related to the machine and hydraulic operations, as well as the drilling fluid under high pressure, and (2) those associated with accidentally striking buried electric power lines or other existing pipelines. Although not considered to be hazardous materials, the proper handling and disposal of drilling fluid is also discussed to avoid possible environmental issues.

Regulations and Damage Prevention (Section 6)

Depending upon the location and extent of the operation, a variety of permits or approvals may be required, possibly from Federal, state or local jurisdictions. These may include the need to file environmental, health and safety plans, or permits for passing beneath waterways, and there may be special requirements for drilling beneath railroads.

Bore Path Layout and Design (Section 7)

The planned bore path, such as illustrated in Figure 2, must be consistent with the steering capability of the maxi-HDD equipment as well as the bending capability of the drill rods. The stiffness of the steel drill rods determines their allowable curvature, in order to avoid fatigue. Unnecessarily large curvatures (sharp bends) also contribute to bending stresses in the HDPE product pipe, although are generally not significant for such a flexible product. Additional route bends, beyond those shown in Figure 2, as well as possible bends in the horizontal plane, should be avoided, and will increase the required pulling forces.

Pipe Design and Selection Considerations (Section 8)

Any pipe installed by HDD is subject to loads of a different type and/or magnitude than that experienced in other construction methods, including by direct burial in a trench. In addition to external pressures due to the head of the relatively dense drilling fluid/slurry or subsequent (post-installation) soil loads, the pipe must withstand the axial tensions induced during the pullback process. While the document provides

| 24 | JANUARY/FEBRUARY 2023 TEXASh2o www.tawwa.org

useful information for evaluating the potential for collapse under lateral pressures, either during of following the installation, the most widely used portion of ASTM F1962 is the set of formulae for estimating the pulling tensions corresponding to the leading end of the pipe reaching point A, B, C and D. These formulae account for the frictional drag acting on the pipe along the surface of the borehole, primarily due to the high buoyant weight of the HDPE pipe, within the relatively dense drilling fluid, especially for vacant pipe, but are sufficiently general to consider the possible implementation of anti-buoyancy measures to reduce these otherwise high frictional forces. (The theoretical basis for the formulae for estimating the required pulling force is provided below.) Thus, a commonly used procedure for difficult or very long installations is to fill the pipe with water to reduce the buoyancy. In the absence of ballast, the maximum total calculated tension will typically occur towards the end of the installation; e.g., at point C or D.

The net resulting peak tensile stress is required to be less than the safe pull tensile stress of the HDPE pipe. The physical properties of the PE material(s) are provided in the appendices, which allow a determination of an appropriate wall thickness for the pipe, depending on the pipe diameter and estimated peak pulling force (or tendency to collapse). Software tools such as Boreaid® (www.boreaid.com, www.ppiboreaid.com), are based on the ASTM F1962 document and model.

Implementation (Section 9)

Due to the magnitude and complexity of maxi-HDD equipment and control systems, a well-trained, experienced crew is essential to plan and execute the operation. The initial decision involves selecting the size and capacity of the machine, which, at a minimum, should be able to provide the necessary pulling force based on the estimated required pulling force for the pipe itself, with possible additional capacity for accomplishing reaming. It is important to properly use the drilling fluid for the initial pilot bore and reaming operations, and to accurately locate and track the bore path. The pipe must be securely gripped, including a swivel and possible breakaway link. As-built drawings must be provided, preferably supplemented with

details of the soil characteristics and drilling operation.

Inspection and Site Cleanup (Section 10)

The HDPE pipe should not be cut prematurely, but should first be allowed to reach mechanical and thermal equilibrium, to avoid shrink back onto the bore hole. The exposed leading end of the pipe should be inspected for possible damage, and a pressure or leakage test may be required, for fluid transport applications.

Appendices

The ten main sections outlined above are supported by several appendices which provide the physical properties of the HDPE (PE4710) material as well as a means of determining the post-installation loads and pipe deflection.

Theoretical Basis for Load Estimation

The theoretical model used to develop the formulae for estimating the peak required tension assumes that the local frictional drag forces on the pipe are proportional to the local normal bearing forces applied at the pipe surface. For flexible PE pipe, with minimal bending stiffness, the considered bearing forces are those due to the dead (empty) weight of the pipe where above ground, the buoyant weight of the submerged pipe (possibly reduced by the use of ballast), or the bearing forces resulting from (previously induced) pipe tension tending to pull the pipe snugly against any curved surfaces ("capstan effect"). In addition, there is a contribution due to the drilling fluid/slurry flowing along the length of the pipe, but which is relatively low, based on the present model.

Frictional Drag Due to Weight and Buoyancy

In the absence of anti-buoyancy techniques, such as internal water ballast, the frictional drag developed within the borehole is generally much greater than that developed outside. Because of the high buoyant weight for an empty PE pipe. For such cases, the buoyant weight of the submerged pipe, in combination with the corresponding frictional characteristics, is the major factor in determining the required pull force. ASTM F 1962 provides formulae for determining the buoyant

CONTINUED PAGE 26 | the perfect match

CONTINUED FROM PAGE 25 | the perfect match

weight under various conditions. The buoyant weight is a function of the density of the drilling fluid/slurry, for which a conservatively high value is suggested for design purposes.

Capstan Effect at Bends

Although pipe stiffness effects may generally be ignored for flexible PE pipe, there is nonetheless a potentially important effect due to route bends or any path curvature that should can be significant. Tensions induced in the PE pipe as it passes any curve, become amplified because the tensile forces tend to pull the pipe against the curved surface. Such effects are independent of the pipe stiffness, pipe diameter, borehole clearance, radius of curvature or direction of curvature, and, in some cases become a major consideration due to their compounding effect. This phenomenon is referred to as the "capstan effect" as it is the principle of the capstan winch, as illustrated in Figure 3.

However, for the geometry shown in Figure 2, with relatively shallow entry and exit angles, the associated load amplification due to this effect is not major, although for more complex paths the effect could be very important. Mini-HDD applications, for instance,

tend to contain bore paths with additional curvature because of the need to avoid known obstacles or follow a curved right-of-way, as well as more subtle curvature due to path corrections characteristic or these typically less precisely controlled installations.

Hydrokinetic Surface Drag (Fluidic Drag)

The effect of the shear forces directly imparted on the surface of the pipe by the drilling fluid ("fluidic drag") has been handled in a widely disparate manner within the industry, and is sometimes considered to be a major consideration. In contrast, the convenient model employed in ASTM F1962 results in a very low magnitude effect, which is directly added to the estimated pulling forces due to the frictional drag, including the capstan effect.

Summary

The recent (2022) edition of ASTM F1962 has revised the relevant physical characteristics of the PE materials, providing the physical properties for the most recent high density polyethylene (HDPE) material, PE4710.

This material is significantly tougher than older, previously used PE products, facilitating successful completion of more complicated, difficult maxi-HDD projects. The physical properties of the PE4710 material allow greater pulling forces and also provide greater resistance to collapse.

Unfortunately, Mary Rhodes is no longer with us today to further champion these causes, but what a water legacy she has left behind. Fortunately, the City of Corpus Christi has new leadership in Mayor Paulette Guajardo, who is working hard to ensure that Corpus Christi continues to develop its water supplies with a strong focus on environmental stewardship, resiliency, equity, and of course financial viability.

So where does Corpus Christi go from here as it relates to developing its water supply portfolio? The eighth largest city in Texas, and regional water provider for seven counties, has a lot of pressure to deliver a viable, economical, and sustainable solution. The City, like many other cities around the country, is seriously considering a number of bold options as outlined below, and perhaps, a combination of one or more

alternatives will be implemented.

Groundwater, a drinking water source used extensively by many municipalities around the State, tends to be brackish in the Texas Coastal Bend with Total Dissolved Solids (TDS) generally over 500 mg/l in this region. The TCEQ secondary MCL for TDS is 1,000 mg/l, whereas the EPA’s secondary standard is 500 mg/l. Exceeding these values would not be acceptable, and a reliance on groundwater in an already compromised aquifer where water quality will not improve over time is problematic. Then there are the issues of land subsidence when pumping groundwater—just look at Houston where some areas of the city have sunk by 8 to 10 feet.

Capturing wastewater effluent could potentially be used as an ultimate water source, but not without some challenges. Corpus Christi has been evaluating the possibilities of using wastewater effluent as a source of water for Aquifer Storage, and Recovery (ASR) as part of an Indirect Potable Reuse (IPR)

approach. The technology is proven; however, the challenge is that the effluent is relatively minimal and localized, thereby requiring it to be conveyed to an aquifer, where additional treatment may need to occur prior to injection into the aquifer for storage. The next step would require the recaptured water to be pumped to a water treatment plant for advanced treatment. From an environmental standpoint, the city is contractually bound by an Agreed Order to release specific quantities of water to the bays and estuaries, and wastewater effluent is one of several resources that positively contributes to these environmental flows.

Ultimately, the most drought-proof, sustainable, environmentally-responsible, and cost-effective approach given the proximity to the Texas Gulf Coast, where an endless supply of raw water exists in our backyard, is seawater desalination. The concept of seawater desalination has been studied by experts in this region for many years. While it has some opposition, much of it unfounded, it checks most, if not

all of the important criteria for Corpus Christi’s next water supply. It has been successfully used by many drought-laden cities around the world for many years.

Senator Perry, the Chair of the Water, Agriculture, and Rural Affairs Committee, is currently drafting a bill that would create a Water for Texas Fund to support water infrastructure and supply projects across Texas. One of the proposed provisions is to disburse funds specifically for desalination projects. This is exciting, promising and something that anyone who lives in Texas, especially along the Gulf Coast, is watching closely.

As I write this, we do know of some legislation that

cover the short term costs, much less even the three to five year infrastructure issues.
