Sanitary Sewer Relining

The purpose of the sanitary sewer relining project is to provide reliable wastewater management for residents and visitors. Sewer mains that were installed 35 years ago are feeling the effects of hydrogen sulfide corrosion, severely damaging the structural integrity of the concrete pipe.

The project will extend the lifespan of the existing infrastructure through the application of trenchless rehabilitation technologies wherever possible. This technology will extend the operational life of the trunk main and reduce costs without the need for excavation or replacement of the line. The relining project will mitigate any further corrosion, address defects and prevent ground water infiltration entering the sanitary system.

During 2020, two components of the project  were completed. The first was the replacement of a manhole and a portion of the trunk main on Village Gate Blvd at the intersection of Highway 99. The second was the replacement of a manhole and relining of a portion of the trunk main adjacent to the Whistler Golf Course between Whistler Village and Blueberry Drive.

Road and Valley Trail traffic interruptions

Work will be performed along the trunk main one section at a time. There may be traffic disruptions on roads and the Valley Trail near where work is being completed.

Traffic management 

Signs will be posted in the affected areas. Flag persons will be on site to manage traffic flow. Pedestrians and cyclists will be directed to walk around the work areas marked by traffic cones while maintaining physical distance from workers and other trail users.
