Located in north-central Saskatchewan, the Lac La Ronge Indian Band (LLRIB) is the largest First Nation in Saskatchewan, and one of the 10 largest in Canada, with a population of just over 11,000, as of March 31st, 2021.

LLRIB’s reserve lands extend from rich farmlands in central Saskatchewan, all the way north through the boreal forest to the mighty Churchill River and beyond. Its central administration office is located in La Ronge, 241 km north of Prince Albert, on the edge of the Pre-Cambrian Shield.

“We are proud of our heritage and our Cree language, and of the educational opportunities, economic successes and social development work made possible by many years of strong leadership.”

Stanley Mission is a First Nations community in the boreal forest northern Saskatchewan, Canada, a reserve of the Lac La Ronge Indian Band government with a population of 1,634. Its location is on the banks of the Churchill River, north east of the town of La Ronge, and north of Prince Albert.

Stanley Mission is a rapidly growing and progressive community and as such requires solid basic infrastructure such as access to good clean drinking to support growth. Access to good drinking water and good wastewater facilities is critical to support growth of any community. Stanley Mission IR #157 requires such water and wastewater facilities to permit the economic and population growth going into the future

To improve water quality and provide sustainable water resources, the Stanley Mission First Nation Water Treatment Plant is undergoing a significant upgrade to their existing facility, as well as the construction of a new raw water intake building. The treated water provided to the First Nation was high in disinfection by-products and was not meeting existing drinking water quality guidelines. The new and improved process will bring the treated water quality within the existing guidelines.

“This project will allow for additional treatment equipment to be installed to ensure the delivery of clean drinking water to the community,” Project Manager from Associated Engineering, Bob Hergott. “With upgrades to the emergency power, motor control, advanced state of the art processes and automation, this facility will supply the needs of the community for years to come.”

The project consists of an expanded water treatment plant which includes an updated and new process to improve treated water quality. There is also a new raw water pumphouse, new raw water intake, and discharge line.

“The expanded and improved water treatment has a design with a 10-year horizon,” says Hergott. “The expanded and improved water treatment and supply systems are estimated to be adequate until 2028.”

When asked what will the project delivery in terms of additional treatment equipment, Hergott explains that a Trident package filtration system (one refurbished existing unit and a new unit), and reverse osmosis membrane system, ultraviolent and chlorine disinfection are included in the project delivery.

“A generator is installed in the WTP to provide backup power for distribution pumping system to provide continuous water supply to community during the power outage,” he says.

The expanded WTP has an electrical room to house all 600V motor starter and variable frequency drives. A programmable logic controller is used to control and monitor the operation of the water supply and treatment system, and online instruments are installed at each step of treatment process to monitor the overall plant performance.
