McEwen Sanitary Pump Station construction update
The City of Ottawa completed all the preparation to resume the rehabilitation of the flow through sanitary pumping station near you, however construction cannot start as planned due to the Hydro Ottawa strike. We cannot start this work without Hydro Ottawa disconnection of existing electrical services.
Due to the above conditions and following careful consideration of all available options, we have to postpone the majority of work planned under the second phase of construction at the McEwen Sanitary Pump Station until Hydro Ottawa returns from strike.
More information about the project can be found at ottawa.ca/ottawawestpumpingstations.
What: This project will upgrade four (4) existing ‘flow through’ sanitary wastewater pump stations located in Bay Ward (Ward 7) to improve their operation and reliability. The flow through stations normally operates as a gravity sewer; however, they switch operation from a gravity sewer to a sanitary pump station once the downstream receiving sanitary trunk sewer is surcharged or overtaxed to prevent upstream basement flooding.
Improvements are required for upgrades for reliability and resiliency as the current configuration requires regular maintenance and manual operation. The proposed upgrades include installing new backup generators required for emergency situations, replacing existing pumps with two (2) new pumps (one duty and one standby/backup), updating electrical and instrumentation to current standard requirements and other miscellaneous improvements.
The first phase of work at the McEwen Sanitary Pump Station completed in 2022 included constructing concrete pads, installing a duct bank below the road and installing new electrical kiosks on the concrete pad.
The second phase of work will include installing the generator, replacing the pumps, and making the necessary connections.
Why: Due to the age, condition and level of operation and maintenance required for the existing infrastructure and the lack of redundancy from basement sewer backup protection, the City will be proceeding with the completion of the work required to improve the reliability of these pumping stations. The project will upgrade each station to have redundancy in pumping (duty/standby configuration), resiliency in instrumentation monitoring, power and controls to reduce the likelihood of having a failure that could result in flooding.
When: The second phase of construction for the McEwen Sanitary Pump Station timeline will be re-evaluated when the power disconnection date is provided by Hydro Ottawa.
Where: McEwen Sanitary Pump Station: 31 McEwen Avenue.
All proposed upgrades will be installed within City right of way or within existing legal City Utility Easement. Proposed backup generators will also be installed within City Park Land or City right of way.
Who: The City of Ottawa has retained the contractor, Black & McDonald Ltd., to complete the work.
