Sump Pump Installation
in Silver Valley, BC

Silver Valley is one of Maple Ridge's newest residential communities, carved out of forested hillside on the slopes above the Alouette River valley. Development here has been ongoing since the 1990s and continues today, with the community still adding new streets and neighbourhoods on the upper mountain slopes. The terrain is steep, the soils are a mix of shallow glacial till and more organic forest soils, and rainfall is higher than the valley floor due to the orographic effect of the adjacent mountains.

Surrey receives roughly 1,500 millimetres of precipitation annually, with the bulk of it arriving between October and March. For homes with crawlspaces, especially those in lower-lying areas of Newton, Bridgeview, or along the Serpentine and Nicomekl river floodplains, that volume of rainfall can overwhelm perimeter drainage and allow water to accumulate beneath the floor. A properly sized and installed sump pump is the most reliable mechanical defense against crawlspace flooding.

The choice of pump matters significantly. Sump pumps are rated by horsepower and gallons-per-hour capacity, and the right specification depends on the size of the drainage catchment area and how quickly water accumulates during peak events. Undersized pumps run continuously during heavy rain events, wear out faster, and may not keep pace with inflow. We size pumps to handle well above the expected worst-case scenario for a given home's drainage conditions.
