Lillooet Wastewater Treatment Facility - Secondary Treatment Plant in British Columbia, Canada

The Lillooet Wastewater Treatment Facility serves the community of Lillooet, located in the Squamish-Lillooet Regional District of British Columbia, Canada. This operational plant provides secondary treatment for a population of 1,515 residents, reflecting its role as a small-scale municipal facility in a rural setting. As a secondary treatment plant, it meets the standard requirements under Canadian wastewater regulations, which mandate treatment to reduce organic matter and suspended solids. The treated effluent is discharged into the local watershed, which ultimately drains into the Fraser River system. This river is a vital ecological corridor in British Columbia, supporting diverse aquatic life including salmon populations. The plant's operations contribute to protecting downstream water quality in this sensitive river ecosystem.

The plant discharges into the Fraser River watershed, one of Canada's most significant river systems. The Fraser River supports critical salmon runs and diverse aquatic habitats. Downstream, the river flows through the Fraser Valley and into the Strait of Georgia, a biologically productive marine environment. The plant's secondary treatment helps reduce nutrient and pollutant loads to this ecologically important basin.
