Tranquille Road Sanitary Main Upgrade Homepage Tile

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 - Completed in 2017

Phase 2 – Southill Street to 12th Street - Construction 2020/2021

Phase 3 – Crestline Street to Southill Street - tentatively planned for 2025 or beyond

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.

The City is committed to engaging the public and stakeholders throughout the project.

Please note that residents are advised that throughout the construction period, vibratory compaction equipment will be in use; therefore, any fragile items should be packaged or protected from any damage due to vibration.

    What Does “Local Traffic Only” Mean?

    We receive lots of questions, requests and concerns from people when a road project is underway, particularly if it is as impactful as the Tranquille Road Sanitary Main Upgrade project. One request that we receive is for “Local Traffic Only” signage to be placed on neighbouring streets as motorists often use streets other the designated detours to find their way around the construction.

    We find that there is a lot of confusion around what “Local Traffic Only” means. “Local Traffic Only” signage is meant to tell motorists that only those residents who live on that street are supposed to travel on that street. Unfortunately, many times the signs are misinterpreted to mean “everyone who lives in the community”.

    We ask that motorists please continue to use the designated detour routes, follow traffic control devices and personnel, and adhere to posted speed limits. As Dr. Bonnie Henry says: “Be kind. Be calm. Be safe.”

    Detour routes, project updates, and traffic webcams (including a new web cam on Tranquille Road at Singh Street), can be viewed at LetsTalk.Kamloops.ca/Tranquille.

    What can be done about motorists speeding on neighbourhood streets near the construction site?

    Kamloops RCMP has launched a new online tool that allows people to report traffic safety issues including speeding, distracted driving, or failing to follow road signs or signals. Through the website a report and file number will be generated. The website can be found here.
