The Commission’s facilities include the following:
• The Wastewater Treatment Plant (WWTP), located in Strathcona County near Fort Saskatchewan, is a state-of-the-art wastewater treatment facility which uses biological processes to produce a high quality effluent. The plant reduces the oxygen demand of the effluent and removes solids, phosphorous and nitrogen from the wastewater. Effluent is disinfected by ultraviolet light before discharge to the North Saskatchewan River.
• Five large-capacity wastewater pumping stations located throughout the regional transmission system.
• Five wastewater transfer stations where domestic wastewater is accepted from residential homes and industrial, institutional and commercial facilities that are not connected to a sanitary sewer system.
• There are 196 km of trunk sewers comprised of forcemains and gravity sewers connecting member municipalities to this Plant.
About 50% of the ACRWC’s assets are all located in the transmission system located within an hour’s drive of the WWTP. The estimated replacement value of the ACRWC’s assets is about $500 million dollars. Flows from our southern members are treated at the City of Edmonton’s Goldbar WWTP.
Current Capital Projects
Upgrades and work being completed on the ACRWC transmission infrastructure in the Alberta Capital Region are further detailed below. These sections are regularly updated with details in regards to the works and approximate timelines of construction and completion.
Waste Gas Burner Facility Upgrades - ACRWC Wastewater Treatment Plant
The ACRWC is undertaking a project to upgrade the Waste Gas Burner Facility. The project will involve the construction of a new Waste Gas Burner Building and flares, a Condensate Room inside the basement of the existing Digester Control Building, all associated process and building systems, commissioning of the new burner system, and demolition of the existing flare building and systems. The project is being completed to upgrade out of date infrastructure to accommodate future biogas production.
Construction started at the beginning of May 2020, and is expected to be completed in the fall/winter of 2021.
The work will take place at the ACRWC Wastewater Treatment Plant (WWTP), 23262 Township Road 540, Fort Saskatchewan. The existing flare system will be operational until the new system has been commissioned and any required connections/tie-ins will be coordinated with the WWTP control center, to minimize impact to operations.
ACRWC START/Outfall Rehabilitation – 2021 CN and Pembina Crossings
The ACRWC will abandon/remove/rehabilitate existing wastewater sewer pipe and install new wastewater sewer pipe between 34 Street and Manning Drive (~1,614 m of sewer abandoned/installed and ~101 m of sewer rehabilitated).
The goal of the project is to address the poor structural condition of the pipes and to increase pipe capacity.
Construction will commence in late March/early April with work being completed by the end of May/early June.
Valour/195 Avenue at the CN Rail crossing will be reduced to one lane for 2 weeks in early April. Temporary and short duration traffic disruption may occur when trucks and equipment are turning in and out of the construction accesses. Bypass hoses may be located within road right of ways.
St. Albert Pump Station Pumping and Electrical Upgrade
The ACRWC will install two additional pumps with variable frequency drives and modify the existing electrical system for improved control and monitoring
The goal of the project is to add redundant pumps to the existing two pumps already in the station and upgrade the electrical.
Construction will commence in late March with work being completed by the end Dec 2021
No public impact is expected as all work to take place within the station
