The Sanitary Sewer Servicing Strategy is a 75-year plan to facilitate sanitary sewer development in undeveloped areas, and redevelopment in mature neighbourhoods.

The program includes the planning and construction of new sanitary transmission trunks larger than 1050mm in diameter or those that service areas greater than 1,400 ha.

The construction projects under this program are implemented on an as-needed basis, and are funded by the Sanitary Servicing Strategy Fund.

Program Scope

This program covers the following 5 new major trunk systems. These systems along with existing sewer upgrades are designed to convey wastewater from the growth areas to the Gold Bar Wastewater Treatment Plant, and the Alberta Capital Region Wastewater Treatment Plant.

  • North Edmonton Sanitary Trunk
  • South Edmonton Sanitary Trunk
  • West Edmonton Sanitary Trunk
  • Clareview Sanitary Trunk
  • Terwillegar University Farms Sewer

Since the program started, approximately 31 km of tunnels and trunk sewers covering various portions of the 5 trunk systems have been installed. This supports about 44,000 single family lots and multi-family residential, commercial and industrial developments.


  • land development is not restricted or delayed due to sanitary servicing constraints
  • the funding mechanism for sewer construction is equitable and affordable to developers
  • reduces the risk of basement flooding by controlling discharges to sewer system during storm events.
  • promotes economical growth of the City
  • promotes regional collaboration
