Sanitary & Storm Sewer Installation
Gravity and pressure sanitary sewers, storm drainage systems, and trunk sewer construction across Metro Vancouver and the Lower Mainland.
What Is Sanitary & Storm Sewer Installation?
Sanitary and storm sewer installation involves laying underground pipe networks that carry wastewater and stormwater runoff away from homes, businesses, and roadways. Gravity sanitary sewers transport waste to treatment facilities using carefully engineered slopes, while pressure sanitary sewers use lift stations to move wastewater where gravity flow isn't possible. Storm drainage systems manage rainwater and surface runoff to prevent flooding, and trunk sewer construction handles the large-diameter main lines that collect flow from entire neighbourhoods. Our crews excavate the trench, place and bed the pipe to specification, install manholes and catch basins, and connect services to the municipal sewer system. Pedre Contractors has installed sanitary and storm sewer systems throughout Langley, Metro Vancouver, Whistler, Vancouver Island, and Kelowna, meeting the standards of every municipality we serve. For full development infrastructure, we also deliver complete site servicing packages that bundle sewer, watermain, and road building under one contract.
When Is Sanitary & Storm Sewer Installation Needed?
Sanitary and storm sewer installation is necessary when new subdivisions and developments need wastewater and drainage systems connected to the municipal network, when capacity upgrades are required to handle increased flow from growing communities, when aging clay or asbestos-cement pipe is being replaced, and when drainage improvements are needed to manage stormwater and prevent flooding. In Langley and across Metro Vancouver, sewer installation is a standard part of land development servicing, infrastructure renewal, and flood mitigation projects. If your project involves extending municipal sewer service, replacing deteriorated pipe, or managing stormwater for a new development, our crews have the experience to deliver it to specification.
What Does a Sewer Project Require?
A sanitary and storm sewer installation project requires municipal permits, utility locates, and environmental controls before excavation begins. On site, the work demands precise survey and grade control for gravity flow, deep excavation and shoring, pipe bedding and laying, manhole and catch basin installation, inspection and flushing to confirm integrity, backfill and compaction to engineered specifications, and final surface restoration. Proper grading is critical for sewer systems to function correctly, making experienced survey and layout work essential. Coordination with water main installation is often required since watermains and sewers are typically installed in the same corridor. Pedre Contractors manages the entire process in-house with experienced crews and direct owner involvement, so your Langley or Metro Vancouver sewer project is built right the first time.
