Wastewater Treatment Plant

Gibsons’ Wastewater Treatment Plant removes 99% of suspended solids from influent before discharging into the ocean.

In today’s society, we have numerous uses for water, both around the home as well as in commercial or industrial operations. This water becomes “wastewater” once it has been used, whether for washing dishes or clothes, flushing a toilet, or as part of a manufacturing process.

The Town of Gibsons operates and maintains a network of trunk sewers, pumping lift stations and a wastewater treatment plant that connects the Town’s sewer systems. Together, these infrastructure assets enable the Town to responsibly treat the wastewater created by our community.

Gibsons’ Wastewater Treatment Plant (WWTP) was commissioned in 2005. Since then, the Town has consistently invested in upgrades and optimizations at the plant to ensure the best possible effluent discharge that exceeds permit requirements and minimizes odour.

In 2019, a number of optimization and upgrades were completed at the facility, including the construction of an equalization tank, a chemical addition building and a chemical delivery system. Budgeted at $2.1 million, the upgrades were required so that the Town may continue to meet our Provincial permitting requirements to discharge treated effluent into the ocean, and to ensure the plant continues to run as efficiently as possible.

September 2020 – Process Tank Maintenance

Between September 17th and September 29th, the crew at the Wastewater Treatment Plant conducted comprehensive maintenance work on the process tank in one of two Sequencing Batch Reactors (SBR 1). This is a major component of our treatment process which breaks down and removes the ammonia and solid concentrations from our wastewater.

The much-needed maintenance involved cleaning the tank, repairing broken piping, tightening couplings, and replacing 660 membrane diffusers, and will enable the Town to deliver even better wastewater treatment.
