This Colwood Sewer Master Plan, completed in May 2013, evaluates the existing sanitary sewer system, outlines a plan for servicing the City of Colwood (City) in its entirety, provides an overview of sanitary sewer alternatives, and discusses potential impacts of a future western communities’ wastewater treatment plant. In general, this Sewer Master Plan will provide a summary of the existing system and guidance for making decisions regarding the future system.
