Metro Vancouver is building several new water mains in the City of Surrey to continue delivering clean, safe drinking water to the growing communities south of the Fraser River. One of these water mains is the 148th Street Water Main, which connects the south shaft of the new Port Mann Water Supply Tunnel to the existing Whalley Reservoir and Whalley Clayton Main in North Surrey.
The 148 Street Water Main will be constructed over the next two years in two phases: the Port Mann section – along Surrey Road, Wallace Drive and 148th Street from 115th Avenue to 105th Avenue – and the Whalley section, along 148th Street, from 105th Avenue to 95A Avenue. Construction of both sections is now underway.
This essential project will increase the capacity and reliability of providing water to communities south of the Fraser River. The water main will be about four kilometres long, with the pipe 1.5 metres in diameter. The project will also include construction of underground valve chambers along the water main alignment. The valve chambers house pipe connections, valves and other equipment used to manage water flow. They also make it easier for crews to conduct maintenance and repair work when required, without disrupting water service in the area.
This project is being coordinated with the City of Surrey to minimize construction impacts on the community. It is expected to be completed by 2021 when it will be connected to the existing regional water system.
