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.
South East Regional Trunk System – North Sections (SERTS N)
The Southeast Regional Trunk Sewer North (SERTS N) services the community of Sherwood Park and other portions of Strathcona County and the City of Edmonton, conveying wastewater to the ACRWC Wastewater Treatment Plant. From Highway 16, the SERTS N line flows north, generally following the alignment of Range Road 232.
Previous camera inspections of the SERTS N sewer indicate that a 300m long section of 1,200 mm concrete pipe is in poor condition just downstream of Aurum Road, where a steep drop section (approximately 4 m vertical drop) and energy dissipating structure is located, near Township Road 534.
Due to the observed level of corrosion of the pipe section, the pipe will be replaced with a corrosion resistant pipe to be installed by Microtunneling.
The Construction contract has been awarded to Ward and Burke Microtunneling.
Mobilization is underway now on the East side of Range Road 232.
The proposed schedule for construction is from July 2018 to July 2019.
