Construction of a new pumphouse and reservoir atop Mercer Hill is needed to support growth in the northern sections of Clairmont including Clairmont Heights. It will also provide storage for fire protection and strengthen the existing water system for Clairmont and Sexsmith. This project may proceed to tender and construction once the Regional Lift Station is significantly underway, based on development demand. The initial size of the reservoir will be 3M litres and is estimated to cost $9M. This project is growth driven with funding split between the County, Developers and Aquatera.
Funding has been pushed to 2021 as this project cannot occur until the Regional Lift Station project has started.
This project will add additional water treatment capacity to the existing WTP to meet growth within the region. A preliminary design will be completed in 2021 to confirm the technology selection, scope of work, land requirements and cost estimate. Construction will occur between 2023 and 2026 depending on the technology selection. A technology change would require earlier implementation due to capacity restrictions during construction versus twinning the existing facility using current technology which could be completed later.
The estimated cost of $20.4M is based on the 2018 Water Supply Masterplan and results from the first two (of three) phases of WTP Stress Testing completed in 2019. The project is driven by growth.
This project involves the installation of a transmission line from the Mercer Hill Reservoir, to enhance the existing Clairmont water system through a PRV, as there is not sufficient space available around the existing reservoir and pumphouse to provide the required capacity (pumping or storage). This project will follow the completion of the Mercer Hill Reservoir project with preliminary design currently anticipated in 2021 and construction occurring in 2022. The project is estimated at $5.44M driven by growth with funding shared between the County and Aquatera.
This has been delayed to follow the Mercer Hill Reservoir project which will supply these lines.
This project coincides with the City of Grande Prairie’s downtown streetscape improvements project. Water infrastructure replacement will be coordinated as part of the City’s Project. It replaces some of our oldest infrastructure and upgrades to accommodate City plans for intensified redevelopment. Aquatera will be contributing $2.83M towards water infrastructure.
Servicing of the Hughes Lake area requires the construction of transmission lines from the Airport Pumphouse, along with a booster station as an interim solution. A transmission line will be constructed along Highway 43 to service the southern portion of the area, and a second transmission line with a booster station will be constructed to service the northern area near the Highway 43X and Range Road 65/70 interchange.
A trickle feed servicing study will be completed in early 2020 to facilitate design and construction in 2021 which will reduce the anticipated construction costs currently budgeted for 2021. Servicing of the southern area will occur in 2021 at a cost of $4M with the northern area in 2024 at a cost of $10.4M. This project is growth driven.
The Wapiti River is eroding the north bank, increasing the potential for flood related damage to the Raw Water Pump House, Raw Water Intake and Siltation Ponds. This project includes armouring the bank to prevent erosion from occurring and protect the raw water facilities. A new water intake is also required due to changes in the river and a need for additional capacity and redundancy. This project includes expansion to the raw water storage facilities to ensure a sufficient supply of raw water is available to meet demand and provide increased off stream storage if withdrawals from the river are restricted (intake issues, drought or environmental spill).
Preliminary design of the expanded storage capacity was completed in 2018 with construction anticipated in 2024. Design and construction of river bank stabilization using bioengineering to protect the existing intake, pumphouse and storage ponds was completed in 2018 and is being monitored to confirm the success of the work. Stantec has been selected as the engineering consultant for preliminary intake design and permitting; it is expected it will take 12 months to obtain the necessary approvals from the regulators.
Construction is expected to occur in 2021. The overall cost estimate of the project is approximately $32.4M through 2024. Grant funding will be pursued to reduce the cost to Aquatera for the project.
The project involves the construction of a 12-15 million litre reservoir near the WTP to provide additional peak system capacity to meet growth and demand on system. Preliminary work will commence in 2020 to establish pipe alignments and land requirements. Construction is expected to start in 2021 and be completed in 2022. This project is has a cost estimate of $14.1M and is driven by growth.
The Town of Wembley engaged ISL Engineering to complete a preliminary and detailed design for upgrades to their existing lagoon treatment system, to meet discharge requirements for the receiving water body. Construction is anticipated to occur in 2020. It is anticipated that the upgrades will cost of $4M. This project is driven by growth and regulatory requirements.
The project involves the installation of a forcemain from the Regional Lift Station to the Clairmont Lagoon to meet the lift station’s pumping capacity. Preliminary design for the project will be completed in 2021 with construction occurring in 2022 following completion of the Regional Lift Station. The cost estimate for this project is $4.75M and is driven by growth.
This project involves the diversion of the Westpointe area sanitary sewer system into the 116th Street Trunk to help alleviate current surcharging on the 108th Street Trunk line. Detail design of the project and construction across 116th Street was completed in 2019. The balance of the construction work on the diversion line will be completed in 2020.
This project is estimated to cost $4.2M and is driven by risk mitigation.
Administration is currently working on a mud sump system study to identify options and best solution for the ongoing operation of the mud-receiving station, including fluid receiving, drying process and solids handling to facilitate disposal at the landfill as daily cover. It is expected that this study will result in a rate change. The mud sump system has experienced significant growth in the last couple of years and can no longer be operated effectively as it is currently set up. The preliminary design for the best option will be completed in 2020 at a cost of $200K with construction starting in 2021 and an estimated budget of $4.5M.
This is a new project driven by growth and risk management.
This project involves twinning sections of the existing trunk sewer between 100th Avenue and the Mission Heights area to address current surcharging near 100th Avenue, and to address expected surcharging in the College Park area as development occurs in Hidden Valley and Arbour Hills areas. The twinning work will also allow for approximately 480 acres of County (McRae West, Whispering Ridge and Clairmont South West) lands to be serviced via gravity.
A preliminary study completed in 2019 by ISL Engineering identified the scope and the project budget of $6.45M over the next 10 years, in six phases. Preliminary engineering will be completed in 2020 to finalize the twinning sections and sequencing. Following the preliminary design work, detail design for Phase 1 will be completed in 2020 and construction will occur in 2021.
Detailed design will be completed in alternating years, followed by construction the following year, until all six phases are completed. Flow monitoring along the trunk sewer will be installed and used to drive the project phases along with development. The project is driven by growth and risk management.
Continued growth in Clairmont has reached the capacity of the current lift stations in Clairmont. This project is necessary to provide wastewater pumping capacity to accommodate continued growth and address maintenance requirements on three aging lift stations with the installation of a trunk line that will allow abandonment of all three existing lift stations. Detailed design and construction tendering have been completed with award pending an additional grant application by the County. Construction is anticipated to start in 2020 with completion in 2022. The project is driven by growth with funding from the County, Grants and Aquatera.

It replaces some of our oldest infrastructure and upgrades to accommodate City plans for intensified redevelopment. Aquatera will be contributing $2.8M towards sewer infrastructure.
Administration completed an Interim Servicing Study for the Hughes Lake area based on providing gravity sewer services for most of the area. This level of service will require the construction of an interim lift station and forcemain to the 116th Street Trunk sewer along with a portion of the West Trunk initially. Ultimately, the area will be serviced by a larger lift station located near Flying Shot Lake and a forcemain directly to the wastewater treatment plant (WWTP).
The cost estimate of $5.7M is based on the Interim Servicing Study completed in fall 2019. A low pressure servicing study will be completed in early 2020 to facilitate design and construction in 2021 which will reduce the anticipated construction costs currently budgeted for 2021.
This is a new project driven by growth.
