Storm Sewer

A storm sewer is a piping system that collects rainwater from the roof and yard surfaces and channels it away from the building. The system includes gutters, downspouts, underground pipes, and often connects to an infiltration field, drainage ditch, or the municipal stormwater network. The storm sewer is entirely separate from the sanitary sewer that carries wastewater.

Effective stormwater management is fundamental to protecting a building's foundation and surrounding structures. When rainwater is not properly directed away from the building, it saturates the soil around the foundation, increasing hydrostatic pressure and the risk of basement flooding. Over time, poor stormwater drainage can compromise the foundation drain system and cause settlement.

Common problems with storm sewer systems include clogged gutters, disconnected downspouts, collapsed underground pipes, and insufficient capacity during heavy rainfall events. Leaves and debris can block gutter outlets in autumn, causing overflow that cascades down the facade and pools near the foundation. Regular inspection and cleaning, especially in spring and autumn, prevents most issues.

If you notice water pooling near your foundation, overflowing gutters, or erosion patterns in the yard, your stormwater system may need attention. A professional assessment can identify capacity issues, damaged sections, and suggest improvements such as extending downspout discharge points, adding catch basins, or installing a larger infiltration field.
