Sanitary pump stations

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.

This is a map showing the location of the Britannia and Howe Sanitary Pump Station and new proposed generator in Ward 7 (Bay Ward). The pump station and generator are located South on Britannia Road at Howe Street.

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.

This is a map showing the location of the Lincoln Heights Howe Sanitary Pump Station and new proposed generator in Ward 7 (Bay Ward). The pump station is located North on Lincoln Heights Road. The proposed generator is located within Lincoln Heights Park

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.

This is a map showing the location of the McEwen Sanitary Pump Station and new proposed generator in Ward 7 (Bay Ward). The pump station is located north-east on McEwen Avenue. The proposed generator is located within south-east on McEwen Avenue.

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.

This is a map showing the location of the Pooler and Deschênes Sanitary Pump Station and new proposed generator in Ward 7 (Bay Ward). The pump station is located north-east on Pooler Avenue at Deschênes Street.

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 operate as a gravity sewer; however, switch operation from a gravity sewer to a sanitary pump station once the downstream receiving sanitary trunk sewer is surcharged or overtaxed do 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.

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.

Where: The project comprises of four (4) locations:

  • Lincoln Heights sanitary pump station: easement between 219 and 225 Lincoln Heights Road
  • McEwen sanitary pump station: 31 McEwen Avenue
  • Pooler and Deschênes sanitary pump station: 84 Pooler Avenue
  • Britannia and Howe sanitary pump station: 247 Britannia 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. Generators will not operate unless under emergency situations or for monthly preventative maintenance procedures (for 1 hour every 1 or 2 months during regular business hours).

Who: Design consulting firm Stantec Limited, has been retained by the City of Ottawa to develop a detailed design for upgrades to the Ottawa West Flow Through Stations that is currently scheduled to begin construction in 2021 – Please see below tentative schedule.

When: The current general project schedule is as follows:

  • Design completion: May 2021
  • Construction start: fall 2021
  • Substantial performance: spring 2022 (varies based on site location)
