Tranquille Road Sanitary Main Upgrade

Tranquille Road Sanitary Main Upgrade Homepage Tile

March 2020 —The COVID-19 pandemic has put a temporary hold on this project. Please subscribe to the project to receive updates.

The sanitary sewer trunk main along Tranquille Road, which extends from Aviation Way to 12th Street, services a total population of 39,170 and is one of the city’s most critical sewer mains. The trunk main is nearing the end of its life and requires replacement and increase in capacity.

In 2013 and 2014, the City of Kamloops hired a consultant to assess the condition of the Tranquille Road sanitary gravity main from the North Primary Lift Station to 12th Street, using CCTV and sonar assessment. From the study, the City prioritized replacement of the gravity main into 3 phases:

Phase 1 - North Primary Lift Station to Crestline Street;

Phase 2 – Southill Street to 12th Street; and

Phase 3 – Crestline Street to Southill Street.

In 2017, the City of Kamloops replaced the sanitary gravity main from the North Primary Sewer Lift Station (near the Kamloops Airport) to Crestline Street and Tranquille Road, which included upsizing the new gravity main from a 900 mm main to a 1,050 mm main.

For Phase 2, a 900mm PVC gravity main will be constructed within the existing road right of way and is anticipated to start in early spring 2020. In addition to the main replacement, proposed upgrades along the corridor include pedestrian paths, landscaping, and intersection and boulevard improvements.


What is a gravity main? A gravity main is a pipe that conducts water, sewer or runoff through the pipe network using the force of gravity.

What is a lift station? A lift station is a pumping station that moves waste to higher elevations, discharging into a nearby gravity manhole or a treatment plant.

The City is committed to engaging the public and stakeholders throughout the project and will be hosting a public information session this spring to review the design, discuss project execution, and hear any concerns.

  • Tranquille Road Sanitary Main Project Will Break Ground This Spring

    about 1 month ago

    Kamloops, BC - In 2017, the City of Kamloops replaced the sanitary gravity main from the North Primary Sewer Lift Station (near the Kamloops Airport) to Crestline Street and Tranquille Road.

    In the second phase of that project, a gravity main will be constructed along Tranquille Road from Southill Street to 12th Street to replace the existing gravity main. The project is expected to start in mid-March, with an anticipated completion of November 2020. In addition to the main replacement, proposed upgrades along the corridor include pedestrian paths, landscaping, and intersection and boulevard improvements.

    Kamloops, BC - In 2017, the City of Kamloops replaced the sanitary gravity main from the North Primary Sewer Lift Station (near the Kamloops Airport) to Crestline Street and Tranquille Road.

    In the second phase of that project, a gravity main will be constructed along Tranquille Road from Southill Street to 12th Street to replace the existing gravity main. The project is expected to start in mid-March, with an anticipated completion of November 2020. In addition to the main replacement, proposed upgrades along the corridor include pedestrian paths, landscaping, and intersection and boulevard improvements.

    While every attempt will be made to minimize the impact on business owners, residents, motorists, transit users, and pedestrians during construction, delays and congestion are inevitable and should be expected. Commuters are encouraged to consider using alternate routes or other modes of transportation, such as carpooling, transit, cycling, or walking.

    The City will work closely with essential service providers, including Kamloops Fire Rescue, BC Ambulance Service, the RCMP, and Kamloops Transit, to ensure service is maintained through the construction area.

    Residents are invited to attend a drop-in information session on Thursday, March 5, between 5:30 pm and 7:00 pm at the Sports Centre Lounge, McArthur Island (1665 Island Parkway) to view the project design. Staff from the City, the designing consultants, and the leading contracting contender will attend to provide information and answer questions.

    The City will implement an extensive communications plan that utilizes traffic webcams, electronic roadside message boards, radio and print ads, social media, the City’s website, and other means to inform the public of anticipated delays, lane closures, and other traffic disruptions.
