  • The city has three different types of sewer systems to deal with the stormwater from rainfall and wastewater produced by daily activities.

    Storm sewer systems capture and convey natural runoff through a network of ditches or pipes and then discharge it into the natural bodies of water through gravity and pump station outfalls.

    Sanitary and combined sewers are an underground network of service connections, pipes, manholes and pump stations that collect and convey wastewater to the regional trunk sewers and wastewater treatment plants operated by Metro Vancouver.

    Combined sewer systems collect both the sanitary sewage and storm water into a single pipe. The city is replacing this type of sewer because during large storms the rainwater can result in the system reaching its capacity and overflowing into the Fraser River.

  • The city regulates the sewer systems through the Sewerage and Drainage Regulation Bylaw No. 7746, 2015.

    Further to the city’s bylaw a regional Integrated Liquid Waste and Resource Management Plan (ILWRMP) is in place to ensure each municipality complies with the provincial objective.

    The regional Integrated Liquid Waste and Resource Management Plan was endorsed by City Council in 2010 received ministerial approval in December 2010.

  • The Engineering Department develops future capital plans to deal with increased discharge attributed to the city’s population growth and aging sewer system.

    To assist with future planning, the City has developed a computerized sewer model to evaluate the capacity for both existing land use and future zoning. The model was used to develop the Master Sewer Servicing Study, which identifies existing and future upgrades.  The Master Sewer Servicing Study is currently being updated.

    The City monitors the current condition of the sewer system by tracking the number of service repairs and completing periodic video inspections of each pipe. This provides a good indication of when sewer pipes, service connections or pump stations should be considered for replacement or rehabilitation.

    Considering both the condition of the pipe as well as the capacity of the system the engineering department develops capital plans that identify the required sewer system upgrades. As development patterns change and the city system ages it is necessary to review annually the capital plans prior to adopting the Annual Capital Works Plan for the current year.

    The regional Integrated Liquid Waste and Resource Management Plan approved by New Westminster City Council mandates us to separate our entire sewer system at a rate of 1.5 % of the system per annum.  This translates into the installation of approximately to 1.5  to 2.0 km of new storm sewer pipes per year.  New buildings and some existing buildings are required to connect to the new storm sewers, as per the Sewerage and Drainage Regulation Bylaw No. 7746, 2015.
