Capital Projects

ACRWC Infrastructure

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.

Fort Saskatchewan Forcemain Twinning

Project Background

Sanitary flows from Fort Saskatchewan, Gibbons, Bon Accord and parts of Sturgeon County flow by gravity to the ACRWC’s Fort Saskatchewan Pump Station (FSPS) located on the North Saskatchewan River just NE of the Village of Lamoureux.


The FSPS pumps the flows into an existing 5km long, 600mm diameter forcemain that ends near the intersection of Highway 37 and Manning Drive.


Through a public tendering process, the ACRWC hired the Borger Group of Companies to install a new 750mm diameter forcemain in the existing ACRWC right of way. The new second forcemain is made of High Density Polyethylene pipe. The existing 600mm PVC pipe will remain in place and will be remain fully functional once construction is completed.


Construction Update

Proposed schedule of construction, September 2016 to December 2017.


The new 750mm forcemain has been installed and backfilled. Minor repairs to the original 600mm forcemain have been completed.


Final testing and commissioning of the force main system has been completed.


Minor deficiency work is ongoing and is scheduled to be completed shortly.

Background Information

The Parkland Pump Station is located on the City of Edmonton boundary in Parkland County on the banks of Big Lake. The pump station was built in the mid-1980’s and the existing, and original Back-Up electrical generator system has reached the end of its operational life cycle.

Construction Update

The Construction was awarded to Setanta Contracting Ltd.


The installation of the new Generator system is nearing completion and will be handed over to ACRWC Operations and Maintenance shrotly.


The construction is scheduled to be complete in early 2018.


Gibbons Pump Station HVAC Replacement

Background Information

The Gibbons Pump Station (GPS) was designed and built in the mid - 1980’s and is located on the Sturgeon River North East of the Town of Gibbons.


The existing HVAC units are at the end of life and require replacing.


Construction Update

A Construction contract has been awarded to Modern Niagara


The installation of the new HVAC system will remain within the existing ACRWC property.


The construction is scheduled to be complete in 2018.


Parkland Gravity Sewer Twinning

Background Information

To provide sanitary sewer service to Stony Plain, Spruce Grove and Parkland County, the ACRWC operates the Parkland Gravity Sewer (PLGS).


The PLGS begins in Stony Plain, crosses into Spruce Grove at Atim Creek near Boundary Road and travels along the Southern edge of Grove Drive.  The PLGS then travels North along Jennifer Heil Way and then crosses to the north side of Highway 16.  The PLGS then travels East to the limits of the City of Edmonton.


Along the overall length of the PLGS, there are a series of sanitary service connections for Stony Plain, Spruce Grove and Parkland County.


The ACRWC is currently twinning a 3.2km portion of the PLGS to provide additional hydraulic capacity required to accommodate population growth in the region and increased flows during rainfall events.


The 3.2km twin portion for upgrade begins on the East side of Jennifer Heil Way North of Grove Drive. The project construction area will end near Century Road North of Highway 16.


The Construction period started in July 2017 and it is anticipated that the project will be substantially completed in early 2018.  Soil remediation will need to be done in 2018 once warm weather arrives.


Construction Update

Through a public tendering process, the ACRWC has hired Pidherney’s Construction to complete this project.


Pidherney’s has completed installation of the new twinned gravity line along the entire project area.


Sanitary Flows are now in the new pipe sections.


Soil remediation is underway.


START/Outfall Rehabilitation – 127th Street and 66th Street Crossing

Background Information

PHASE 1: START/Outfall Rehabilitation - 127 Ave Crossing “COMPLETED”


The project has been awarded to PME Construction


The St. Albert Outfall Sewer (Outfall) was constructed in the mid 1970s and the St. Albert Regional Trunk(START) Sewer was constructed in the mid-1980s. Both are owned and operated by the Alberta Capital Region Wastewater Commission (ACRWC) and were constructed to convey wastewater from several communities surrounding Edmonton including St. Albert, Stony Plain, Spruce Grove, Morinville and parts of Sturgeon and Parkland Counties. Both sewers run along the south side of Township Road 542 (also known as Valour Avenue or 195 Avenue) in Sturgeon County, to the ACRWC Wastewater Treatment Plant, near Fort Saskatchewan.


The START and Outfall sewers are currently faced with both structural condition problems and hydraulic constraints. The ACRWC has identified that the section of both sewers that cross 127 Street should be replaced and realigned. The new alignment will reduce bends in the sewers to reduce hydrogen sulfide release and ensure that manholes are outside of the 127 Street roadway for future maintenance.


The ACRWC, through a public tendering process has hires PME Inc. to complete the construction of the 127th Street upgrades.


The scope of the project will include:

  • Replace approximately 60m of the Outfall Sewer and approximately 60m of the START sewer under 127 street using open trenching (both new pipes will be 1.05 m diameter sewer);
  • Construct 4 new manholes outside of the roadway
  • Abandon and/or remove 4 existing manholes that are currently within the roadway or immediately beside the shoulder of the road

The construction period will begin in mid-June and is scheduled to be complete by September 2018.


Construction will require temporary closure of 127 Street just south of Township Road 542 (north and southbound) for approximately 3 weeks in July/August while the replacement of the sewers under the roadway occurs.


A temporary gravel detour road will be constructed on the west side of 127 Street to maintain north and southbound traffic.


Motorists should expect delays due to a reduced speed limit and temporary traffic signals during the construction.


Bypass pumping of the wastewater flow will ensure that no disruption to wastewater service occurs.

PHASE 2: START/Outfall Rehabilitation - 66 Street Crossing


The scope of Phase 2 of the project will include all trenchless methods to cross 66 Street:

Complete the rehabilitation of approximately 80 meters of the existing 1.50m diameter START sewer using the sliplining method (installation of a new pipe inside the old pipe);

Replace and upsize approximately 90 meters of the Outfall sewer with a 1.5m diameter pipe using a trenchless method to keep 66 Street open during construction.

Replace 1 manhole and construct 4 new manholes;

Bypass pumping of the wastewater flow will ensure that no disruption to wastewater service occurs.


No road closures are anticipated at the project location just south of the intersection of 66 Street and Township Road 542 (Valour Avenue or 195 Avenue).


The construction period will begin late August and is expected to be completed in October.


Construction Update

The construction is scheduled to be complete by December 31, 2018.

PME has mobilized to 127 Street site and is in the process of moving top soil

South East Regional Trunk System – North Sections (SERTS N)

Background Information

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.


Construction Update

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.
