District of Squamish Wastewater Treatment Plant to receive $10M upgrade for growing community

Construction upgrades to the primary and secondary-treatment processing system at the Wastewater Treatment Plant (WWTP) are set to begin later this month to help meet the demands of a growing community as well as maintain compliance with Federal and Provincial wastewater treatment regulations. The upgrades to the plant will ultimately increase treatment capacity, provide system redundancy, increase seismic and flood resiliency, improve plant performance and effluent quality, while decreasing biosolids production and associated energy usage, carbon emissions and handling costs. $10M was allocated to the WWTP upgrades in the 2022 Financial Plan, with funding for the project to be obtained from Development Cost Charges (DCCs) as well as from Reserves. 

“Our commitment to investment in critical infrastructure is steadfast as we strive not only to keep up with the growth of our community, but to also mitigate the effects of our changing climate,” says District of Squamish Mayor Karen Elliott. “These upgrades are of even greater importance to ensure our critical services are resilient and withstand extreme weather events today and into the future.”   

Upgrades to the WWTP were outlined in the 2015 Liquid Waste Management Plan (LWMP) that identified when the plant would require a capacity increase to meet population growth forecasts and redundancy requirements in accordance with the Municipal Wastewater Regulations. Once construction is complete, the new plant should sustain population growth until approximately 2040 and will provide post-disaster operability and withstand seismic and flood events. The LWMP provides guidance to the District’s services for sanitary, liquid waste and urban runoff issues until 2031. 

The major upgrade works include:

Construction is planned to begin in late April 2022 and continue through to September 2023. The WWTP upgrade is separate and distinct from the upcoming Public Works Facility replacement, for which the District will seek elector approval later this summer to borrow for that project.  

An area on Centennial Way, west of Highway 99 is currently being set up as temporary storage and a truck wash bay which will be utilized by the Public Works Department for the duration of the WWTP upgrades.
