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.
