Nak'azdli Whut'en - Wastewater Treatment and Disposal

The proposed project is the construction of a new wastewater treatment system to replace the existing lagoon system to address operational deficiencies resulting in odour and poor effluent water quality being discharged into the salmon spawning Necoslie River, which is a tributary to the Fraser River. The proposed super tank lagoon system is anticipated to utilize approximately 10, 000 sq. meters (2.5 acres) of land.

The project works include:

  • Installation of a tank lagoon wastewater treatment system;
  • Installation of a new gravity sewer main to curb inflow and infiltration;
  • Installation of service connections;
  • Decommissioning, removal and remediation of existing lagoon system; and;
  • Related civil, electrical, communications and site works.

The components of this system include two super tanks, one operations building and a new outfall. Other project works will include an inflow and infiltration reduction program to identify leaky and broken collection pipes, with an allowance for repairs and replacement of pipes to reduce inflow and infiltration. The outfall will likely discharge to the nearby Necoslie River, but  Stuart Lake is also a possible receiving body, depending on the chosen site. The environmental considerations will be a critical part of design phase.

Naka'azdli Whuten First Nation (NWFN) owns the infrastructure. They have an understanding with the District of Fort St. James (DFSJ) to replace the existing lagoon at the NWFN Reserve Land while operation will be managed by DFSJ. Both these communities use the infrastructure. DFSJ has provided a letter of support.

The project will result in increased capacity to treat and/or manage wastewater and/or storm water.
