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.
