St. Joseph storm pumping station and outfall

Project description

The City of Ottawa is undertaking a preliminary and detailed design for the decommissioning of the St. Joseph Pumping Station, rehabilitation of the pumping station outflow sewer, and installation of a new storm sewer from Forsey Street and Bruyère Street to the Cathcart Street and King Edward Avenue intersection.

The proposed work consists of the following:

• The St. Joseph Storm Pumping Station has reached the end of its useful service life and is to be decommissioned;
• The existing outfall pipe from the pumping station is to be rehabilitated via trenchless methods to minimize disturbance of the affected lands;
• Approximately 440 metres of new storm sewer is to be installed from the existing storm sewer at Forsey Street and Bruyère Street to the storm sewer at Cathcart Street and King Edward Avenue intersection;
• The new storm sewer is to be installed within the greenspace of City property, as much as is feasible, to minimize disturbance to the roadway and other infrastructure and utilities; and
• Existing storm sewer service laterals from Forsey Street and Bruyère Street to the storm sewer at Cathcart Street and King Edward Avenue intersection are to be replaced to City property limits, as required.

Project timing

Preliminary and detailed design: spring 2022 – spring 2025
Construction of storm sewer: summer 2025
Construction of pumping station works: summer 2025 – winter 2026

Construction is expected to start in 2025 and be phased over two (2) years, pending approvals including budget and overall construction coordination. The timing for the project will be confirmed closer to construction.

Budget

Project funds approved to date is $0.75 million.

Public engagement

An online public information session is expected to be held in early 2025, to present the design drawings to the public. At this time attendees will be able to review the design, ask questions and provide comment on the proposed works.

Accessibility

Accessibility is an important consideration for the City of Ottawa. The City makes every effort to provide access through and around construction sites. If you require a disability-related accommodation, please contact the project team listed below. Accessible formats and communication supports are available, upon request.

Safety

The City of Ottawa is committed to safety in and around project sites. The project team continues to work closely with the industry and to comply with recommendations provided by municipal, provincial and federal health officials, as well as the Ministry of Labour, Immigration, Training and Skills Development.

A notice was previously issued to advise of a geotechnical investigation in your neighbourhood required for the design to decommission the St. Joseph Pumping Station, rehabilitate the pumping station outflow sewer, and install a new storm sewer from Forsey Street and Bruyère Street to the Cathcart Street and King Edward Avenue intersection.

The scope of design has been expanded to include full rehabilitation of Bruyère Street between Forsey Street and Rose Street, wherein the roadway will be rehabilitated and the existing watermain replaced. Consequently, construction of this project requires deferral to 2024.

What: The City of Ottawa is undertaking a preliminary and detailed design for the decommissioning of the St. Joseph Pumping Station, rehabilitation of the pumping station outflow sewer, installation of a new storm sewer from Forsey Street and Bruyère Street to the Cathcart Street and King Edward Avenue intersection, and watermain replacement beneath Bruyère Street from Forsey Street to Rose Street.

Why: The St. Joseph Storm Pumping Station has reached the end of its useful service life and is to be decommissioned. Approximately 440 metres of new storm sewer is to be installed from the existing storm sewer at Forsey Street and Bruyere Street to the storm sewer at Cathcart Street and King Edward Avenue intersection. The new storm sewer will take by gravity the flows from the existing storm sewer system, starting at Forsey Street and Bruyère Street and ending at the Cathcart Street and King Edward Avenue intersection, when the river levels are too high to allow the existing 1800mm diameter sewer to outlet into the river. The storm sewer outfall and outfall structure to the river will also be rehabilitated to ensure the continued safe functioning of the system.

Due to difficult condition of the soils along the proposed alignment of the new storm sewer beneath Bruyère Street between Forsey Street and Rose Street, the entire road will be impacted during construction and will require reconstruction, including sidewalk and curbs.

When: Construction is expected to commence in summer 2024 and be phased over two (2) years, pending approvals, including budget and overall construction coordination. The timing for the project will be confirmed closer to construction.

Where: The future construction work will take place on Bruyère Street from Forsey Street to Rose Street, Rose Street to Cathcart Street and Cathcart Street to King Edward Avenue.

Who: The City of Ottawa has retained Robinson Consultants Inc. and their sub consultants (Thurber Engineering Ltd., CIMA+, Clean Water Works Inc., Ruhland & Associates Ltd. and others) to complete the design.

Further information of the plan, construction timing and impacts to the community will be shared in 2024, in advance of construction.

Impact on the right of way and adjacent private properties

The underground investigation work will require the creation of holes into the road surface, which will be reinstated following the investigation. It is not anticipated that private properties will be impacted by this work.

Public information session

A public information session will be held ahead of the future construction works to provide project information to area businesses and residents. Scheduling details of the public information session will be provided to the area businesses and residents.

The City of Ottawa will undertake a geotechnical investigation in your neighbourhood. This investigation is required as part of the design to decommission the St. Joseph Pumping Station, rehabilitate the pumping station outflow sewer, and install a new storm sewer from Forsey Street and Bruyère Street to the Cathcart Street and King Edward Avenue intersection.

What: Work will involve both above ground surveying/cataloguing and underground utility investigations.

Why: The work is being performed in preparation for the storm sewer construction works in Bordeleau Park and on Bruyère Street from Forsey Street to Rose Street, Rose Street from Bruyère Street to Cathcart Street and Cathcart Street from Rose Street to King Edward Avenue, scheduled to begin in summer 2023.

When: This work is expected to begin in July 2022, weather dependent. Soil sample containers may remain on-site for an additional three weeks, pending lab results prior to being removed.

Where: The work will take place at various locations within Bordeleau Park and the adjoining streets of Forsey Street, Bruyère Street, Rose Street and Cathcart Street.

Who: The City of Ottawa has retained Robinson Consultants Inc. and their sub consultants (Thurber Engineering Ltd., CIMA+, Clean Water Works Inc., Ruhland & Associates Ltd. and others) to complete the work.

Traffic

Lane reductions and alternating traffic can be expected to accommodate the work.

Impact on the right of way and adjacent private properties

The underground investigation work will require the creation of holes into the road surface, which will be reinstated following the investigation. It is not anticipated that private properties will be impacted by this work.

Noise

You may notice noise during the underground investigation work. The City of Ottawa Noise By-law (2017-255) allows construction activity to occur weekdays between 7 am and 10 pm. On Saturdays, work is permitted between 7 am and 10 pm, while Sundays, statutory and public holidays work is permitted between 9 am and 10 pm.

Public information session

A public information session will be held ahead of the future construction works to provide project information to area businesses and residents. Scheduling details of the public information session will be provided to the area businesses and residents.
