How Does a Catch Basin Work?



A catch basin, also known as a storm drain, has a grate on top and a drainage pipe that slopes away from the basin. They help maintain proper drainage in streets and public areas. Catch basins trap flowing debris from rainwater or snow melt. This process helps the downstream flow not clog pipes or water sources. The debris is then cleaned out, usually by a vacuum truck.


Supporting Drainage Systems

Catch basins serve as a pre-treatment stage in sewer and storm drains. They catch sediment and large debris flowing in rainwater. Drainage clogs and issues are minimized which means less maintenance for drains. They also keep the surrounding systems from overloading. It's important to keep up with drain cleaning to protect the local water supply. If well maintained, catch basins can be effective for a long time.

Cleaning a Catch Basin

Sometimes catch basins can get backed up from the beginning of its process. Fallen leaves and pine needles can build up and cover grate holes. Lately, you will also see plastic water bottles and other littered items plugging drainage systems.

The most popular method of clearing this waste is by jet vac cleaning. A vacuum truck lowers a hose into the hole and sucks up water and byproduct of sediment and rubble. We offer the service for pubic and residential catch basins.
