Sanitary Sewer

The City is working to build and maintain an effective and reliable sanitary sewer system to service residents and businesses in our growing community.       

Sanitary System Facts

The City has one of the largest sanitary sewer systems in the province. Our system is made up of: 

  • Over 1,500 km of sanitary sewer pipe that carry wastewater from one point to another by gravity
  • Service connections that connect homes and businesses to the sanitary sewer system
  • 21,000 manholes and 80,000 inspection chambers that allow the City to access and maintain the sanitary sewer system
  • 40 pump stations that pump wastewater from a lower elevation to a higher elevation, where wastewater cannot be carried to a sanitary sewer by gravity
  • Forcemains and siphons carry wastewater under pressure from one point to another
  • Odour control facilities to address issues at specific locations

The City's sanitary sewer system connects to several large sanitary sewers that are owned and operated by Metro Vancouver. These pipes carry wastewater to the Annacis Island Wastewater Treatment Plant.

Upcoming Projects

The City has an annual capital construction program as well as a 10 year servicing plan that identifies sanitary sewer system upgrades needed to service the community over the next 10 years. Find out more about current and past tenders, as well as request for proposals, quotations and information for the sanitary sewer program here.

All sanitary sewer system components are designed in accordance with the City's design criteria.
