North Cultus Wastewater Treatment Plant

The North Cultus Wastewater Treatment Plant site is located within the unceded traditional territories of the Stó:lō Peoples and the nearest community of Soowahlie First Nation.

Along with residents, businesses, user groups, and federal and provincial agencies, the FVRD recognizes the value of Cultus Lake and the importance of protecting this sensitive environment with long-term solutions to ensure its sustainability. In 2015 and 2016, the FVRD went through an extensive community engagement process and established a Liquid Waste Management Plan (LWMP), approved in 2019 by the Minister of Environment. The LWMP identified the need for a Wastewater Treatment Plant (WWTP) capable of producing Class A effluent as defined under the BC Municipal Wastewater Regulation, plus additional phosphorus removal to meet the needs of the community and to protect Cultus Lake.

Construction of the new WWTP is a significant investment in community vitality, lake health, and the protection of the Cultus Lake watershed.

The construction of the new wastewater treatment plant includes supply, installation, and commissioning of process equipment.

Two pre-cast concrete buildings will house the process equipment. The main building will house the headworks, blowers, odour control, sludge dewatering, and chemical dosing equipment, as well as the site office. The second building will include tertiary filtration and coagulant dosing.

The treated effluent will be released back into the environment via one of two rapid infiltration basins. Included in the scope of work is also all required process piping, yard piping, electrical (including backup power source), mechanical, miscellaneous instrumentation, SCADA, landscaping and other ancillary works.
