The Alberta Capital Region Wastewater Commission (ACRWC)  provides wastewater transmission and treatment services to 13 municipalities in the Alberta Capital Region. Under the Master Agreement, each regional municipality is responsible for its own infrastructure while the ACRWC looks after the main trunk lines and wastewater treatment. The ACRWC also has a strategic partnership with the City of Edmonton to treat a portion of our respective flows and manage our biosolids.

In September 2008, the Regional Wastewater Exchange Agreement between ACRWC and the City was signed. The objective of the Regional Wastewater Exchange Agreement is to address the changing conditions in wastewater transmission and treatment services in the Capital Region.  In order to address the changes, the parties agreed to the following key items in the new Regional Wastewater Exchange Agreement:


  • Term of the agreement – 20 years (from 2008 to 2028)
  • Rate structure – the rate charged for exchange of services will be the lower of the two rates of each party
  • Joint planning – the parties will jointly plan and discuss future capital expenditures, environmental concerns, and changes to contributing areas
  • Overstrength – the City will continue its current overstrength program while the ACRWC will establish a new program to monitor and exchange overstrength treatment services
