About this facility

The Comox Valley Water Pollution Control Centre processes wastewater for 44,370 residents in the Comox Valley, discharging an average daily flow of 17,000 m3 of treated, safe water to the Strait of Georgia three kilometres off shore.

The Comox Valley Water Pollution Control Centre is classified as a Level IV plant.

How is the sewage treated?

Treatment includes screening and degritting to remove solids, and aeration to ensure water meets safe standards before being discharged. Regular testing is conducted to ensure the system is working effectively.

Solids from the treatment process are collected and taken to the CVRD’s Compost Facility where the biosolids are used to produce nutrient rich soil that can be used for landscaping, orchards, flower gardens and lawns. Visit our webpage to learn more about our SkyRocket product.


The Comox Valley Wastewater Pollution Control Centre was first proposed in 1978 as a replacement for aging municipal and military wastewater treatment facilities. The plant officially opened in March 1984. Shortly after commissioning, the CVRD began to receive odour complaints related to plant operation.

For more information on the history of odour complaints at the plant, and what is being done now to address these concerns, please visit our Sewage Treatment Plant Upgrades project page.
