Coast Envinmental Ltd.

There are approximately 10,000 onsite sewage systems in the Core Area of the Capital Regional District (CRD), with a number of new installations taking place every year. These systems can provide effective, long-term wastewater treatment if working properly. Regular maintenance has a significant impact on how well your system works and how long it lasts. If a system fails, there can be damage to the environment, risk to health of your family, and significant repair costs.

The recently-adopted Bylaw 3479 requires owners with onsite package treatment plants (Type 2 and Type 3 systems) in Colwood, Langford, Saanich &View Royal to maintain their system according to the maintenance plan for the system and to ensure it is maintained by an authorized person at least once per calendar year. Records of this maintenance must be retained by owners, with a copy to be provided to the CRD.

This program takes effect immediately and owners must provide the CRD, by December 31, 2009, with proof of the maintenance undertaken.

The Treatment Process

Wastewater enters the treatment plant through the inlet, and then the aeration process begins. Bacterial colonies grow very rapidly, breaking down the wastewater. This treated effluent then enters the conical clarification chamber.
This device causes remaining solids to drop back into aeration chamber, extending the treatment process. The outlet tee allows only treated effluent to exit to the disposal system, and restricts any remaining solids from leaving.
