Ottawa West flow through pump station upgrades

Project description

The City of Ottawa has initiated the design for upgrades to four (4) existing sanitary pump stations that were originally installed between 1989 and 1994 and located in Ward 7: Bay. Two (2) sanitary pump stations are located within Britannia Village Community and the remaining two (2) sanitary pump stations are within Carlington West-Glabar Park-McKellar Heights Community.

Project upgrade objective

The main objective of the project is to improve the resiliency and reliability of the operation of the four (4) flow-through sanitary pump stations located near the West Nepean Collector (WNC), the level of service (LOS) provided by the stations will be maintained throughout the rehabilitation and retrofit work.

All sanitary pump stations will be retrofitted to provide:

• One (1) duty and one (1) standby pump
• One (1) backup/emergency natural gas generator
• Updated electrical and instrumentation to current City of Ottawa Standards
• Other upgrades including process mechanical piping and ancillary equipment

General station operation

Construction has been delayed due to the Hydro Ottawa strike and is expected to begin in early spring 2024.

What: This project will upgrade four existing ‘flow through’ sanitary wastewater pump stations located in the Bay Ward (Ward 7) to improve their operation and reliability. The flow through stations normally operate 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 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 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 Lincoln Heights Sanitary Pump Station, completed in 2022 and 2023, 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 and power and controls to reduce the likelihood of having a failure that could result in flooding.

When: The second phase of construction for the Lincoln Heights Sanitary Pump Station will commence in early Spring 2024, pending Hydro Ottawa power disconnection date.

Where: Lincoln Heights Sanitary Pump Station: easement between 219 and 225 Lincoln Heights Road. 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.

Beginning in early Spring 2024, the City of Ottawa will resume construction at the Pooler and Deschênes Sanitary Pump Station.

Britannia and Howe sanitary pump station (BHPS) within Britannia Village Community

The Britannia and Howe sanitary pumping station (BHPS) is located at the north east corner of Britannia Road and Howe Street, just north of the National Capital Commission (NCC) pathway. This station was originally constructed circa 1991. This station services residence and buildings north of Howe Street, and bound by the Ottawa River and Mud Lake. A drainage map illustrating the serviced area within the bold dashed black boundary is provided below.

As part of the design for the BHPS, the control and electrical distribution boxes will be moved further away from the NCC pathway to make way for additional landscape features as part of initiatives by the Local Community Association and National Capital Commission (NCC). In addition, a new natural gas generator will be installed in the same fenced enclosure as the new electrical panels.

Lincoln Heights sanitary pump station (LHPS) within Britannia Village

The Lincoln Heights sanitary pumping station (LHPS) is located within a City of Ottawa easement between 219 and 225 Lincoln Heights Road. This station was originally constructed circa 1989. It services residence and buildings north of Richmond Road, east of Croydon Avenue and west of Sir John A. Macdonald Parkway. A drainage map illustrating the serviced area within the bold dashed black boundary is provided below.

The LHPS will remain within the easement between 219/225 Lincoln Heights Road. As part of the project, pumps and mechanical equipment will be replaced, and new electrical and instrumentation panels will be installed. A new natural gas generator will be installed within Lincoln Heights Park and adjacent to 175 Lincoln Heights (including a landscape ‘buffer’). This generator is required for improved reliability of the sanitary pump station and will require a new duct bank to be installed from Lincoln Heights Park to 219/225 Lincoln Heights Road.

McEwen sanitary pump station (MPS) within Carlington West - Glabar Park - McKellar Heights Community

The McEwen sanitary pumping station (MPS) is located at the end of McEwen Avenue on the east side of the cul-de-sac adjacent to 31 McEwen Avenue. This station was originally constructed circa 1994. It services all apartment buildings on McEwen Avenue (30, 31, 61 and 70 McEwen Avenue). A drainage map illustrating the serviced area within the bold dashed black boundary is provided below.

The MPS will remain in its existing location adjacent to 31 McEwen Avenue. Pumps and mechanical equipment will be replaced, and new electrical and instrumentation panels will be installed. A new natural gas generator will be installed further south on McEwen Avenue within Byron Linear Tramway Park. This generator is required to improve reliability of the sanitary pump station and will require a new duct bank to be installed from 31 McEwen Avenue to the new generator location.

Pooler and Deschênes sanitary pump station (PDPS) within Carlington West - Glabar Park - McKellar Heights Community

The Pooler and Deschênes sanitary pump station (PDPS) is located within the roadway of Pooler Avenue adjacent to 85/87 Pooler Avenue. This station was originally constructed circa 1989. It services residences and buildings north of Richmond Road (not along the frontage of Richmond Road), and east of Pooler Avenue, and south of Sir John A. MacDonald Parkway, and west of Aylen Avenue. A drainage map illustrating the serviced area within the bold dashed black boundary is provided below.

The PDPS will remain in its current location; however, a new natural gas generator (with associated panels) will be installed further north within City right of way. Two (2) Trees on NCC land will be required to be removed prior to the installation of this Generator and has been scheduled for March 2021; Replanting the trees (as designated by the NCC) has been planned for 2022 after the completion of this project. Replacement compensation is expected to be a 2:1 ratio (2 new to 1 removed). This generator is required to improve reliability of the sanitary pump station and will require a new duct bank to be installed from the new generator to 85/87 Pooler Avenue. Pumps and mechanical equipment will be replaced, and new electrical and instrumentation panels will be installed.

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.

Traffic impacts

Lane reductions and alternating traffic can be expected during construction to accommodate the work. Access to private properties will be maintained throughout the construction period. Access for pedestrians and cyclists will be maintained.

On-street parking and local access

As the various construction activities are in progress on your street, on-street parking will be restricted. Local access will be maintained to residents, businesses and emergency vehicles. In the event that vehicular access to your property may be unavailable; the Contractor is required to provide 24-hour notification of temporary loss of vehicular access/egress to your property. A temporary On-Street Parking Permit will be made available to allow on-street parking within two blocks of your residence when these disruptions occur.

Impact on the right of way and adjacent private properties

The reconstruction is within the City’s right of way but may result in some disruption to part of the private property directly adjacent to the work. The City will reinstate sections of landscaping, driveways and walkways that are disturbed by construction. However, if you have plants or any other assets located within the City’s right of way that you want to preserve, we suggest that you may want to move them in preparation for the construction work.

Construction disruptions

The Contractor will take every precaution to minimize interruptions to the everyday life of your family and/or operation of your business, but, as you can appreciate, there may be some inconvenience during the work, such as traffic delays, noise and dust. You may also feel vibrations due to heavy equipment operations. Vibrations from construction activities are quite common and are rarely a cause for concern.
