Working together for communities and water professionals

Working together for communities and water professionals in the Northwest Territories

W

ater is a defining feature of the Northwest Territories (NWT) with its abundance of clean lakes and rivers that supply communities with potable water. The management of water from these lakes, rivers and treatment plants (WTPs) is the shared responsibility of all levels of government in the NWT. Community governments are responsible for operating and maintaining WTPs. The Government of the Northwest Territories (GNWT) is responsible for the regulation of water supply systems, providing certification, training and support to WTP operators, and the Federal Government is responsible for the licensing allocation of the water. The GNWT also inspects WTPs and reviews water quality data from communities to ensure the treated water is safe.

There are 30 community water supply systems across the NWT, all of which operate independently. Some of the challenges inherent in operating and maintaining water supply systems, especially with smaller communities,

include remote locations, limited resources (such as qualified operators) and operator retention.

A new element to community water supply is the NWT Water Stewardship Strategy, which was established in 2010. The Water Strategy has set a guiding vision, goals and approaches for water users, planners and regulators. Its vision is for the waters of the NWT to remain clean, abundant and productive for all time.

Of the numerous activities to success identified in the Water Strategy, a key activity is the mapping and protection of community public water supply sources. Maps assist with the delineation of source water catchment areas and are a tool to land use planning around water sources; this is the first barrier in the multi-barrier approach to water management. The goal of the multi-barrier approach to drinking water management is to reduce the risk of drinking water contamination by creating barriers, such as source water protection.

necessary treatment required to make it safe for consumption. In the NWT, the chief public health officer is provided authority under the Water Supply System Regulations to direct operators and owners of public drinking water systems to conduct and perform sampling and testing.

As part of the safe drinking water initiatives, GNWT initiated a pilot project in 2007 to install online water quality analyzers and remote telemetry units to allow Environmental Health Officers to monitor water quality remotely. The primary driver for continuous online monitoring is regulatory. Online turbidity monitoring is required under the updated Guidelines for Canadian Drinking Water Quality.

Remote monitoring systems have the potential to strengthen the multi-barrier approach, reduce human health risks, and facilitate more cost-effective technical support to community operators.

The GNWT approved Water and Wastewater Operator Certification Guidelines in 2006. The guideline set standards for classifying water

“The past decade has brought tremendous change to water supply and treatment in the NWT.” treatment plants and certifying water treatment plant operators. In the NWT, there are four different water treatment plant classifications: Small Systems, Class I, Class II and Class Ill. Classifications are based on a number of criteria, some of which include: type of treatment, source water quality, and the chemicals used in the treatment process.

Operator certification became mandatory on April 1, 2010, with the adoption of Water Supply System Regulations. The GNWT Water and Wastewater Certification Committee approved an option for restricted certification of operators. The certification committee may issue a restricted certification on a case-by-case basis to an operator who was able to meet some, but not all, of the certification components. It is the responsibility of the operator to apply for restricted certification. With the letter requesting restricted certification, the operator and their employer must identify a plan for him/ her to reach full certification. If the certification committee awards restricted certification it will be non-transferrable, limiting the operator’s certification to their own facility.

Since 2002, the GNWT’s School of Community Government has been responsible for delivering the operator certification training program. The Water and Wastewater Program consists of eight courses offering instruction in the areas of water treatment, water distribution, wastewater treatment and collection, and solid waste management.

Material in support of operators is even on the web with an Operators’ Corner website that was developed to give operators easier access to operations and maintenance information.

Other information available on the website includes: water quality sampling instructions; log sheets for regular operations and maintenance tasks; training and certification information; safety and emergency response checklists, and standard operating procedures.

The GNWT has also introduced a circuit rider program to provide hands-on training for operators of water treatment plants, as well as guidance for community administrations Click here to return to Table of Contents

in the development of their drinking water treatment program. The main objective of the circuit rider program is to work with operators in their own facility on operational areas they would like more training in, and to work with them to help them in their efforts to achieve certification to the level of the plant they are operating. A circuit rider travels to assigned communities between two and three times a year to provide training. A couple of days are spent in the water plant assisting the operator and evaluating the system.

Since 2004, the Northwest Territories has been undergoing water treatment plant upgrades due to changes to the Canadian Drinking Water Quality Guidelines. The upgrades to some of the water treatment plants have resulted in a change in the plant classification requiring operators to advance their certification level. In addition, the Water Supply System Regulations, enacted in September 2009, require mandatory certification for water treatment plant operators. For these reasons, and because of high operator turn over, an increased emphasis on training and certification is needed, and the circuit rider program assists communities to address these requirements.

The past decade has brought tremendous change to water supply and treatment in the Northwest Territories with a number of regulatory requirements that directly impact communities and their operating staff.

Fortunately, foresight was applied in the ‘rollout’ of these changes, allowing the water professionals to work together with their community and the senior government to ultimately meet these requirements.
