A catch basin, also known as a storm drain inlet or curb inlet, is a type of drainage infrastructure that collects and filters water runoff from streets, parking lots, and other paved surfaces. It is typically a large, rectangular or round box made of concrete or other durable materials that is installed into the ground and covered with a grate or cover.
Catch basins are designed to capture and filter out debris, sediment, and other pollutants from stormwater runoff, helping to prevent flooding and water pollution. When it rains, water flows into the catch basin through the grate or cover and collects in a sump or basin. The water then flows out of the catch basin through an outlet pipe, which carries it to a nearby stream, river, or other drainage system.
Catch basins are an important component of a larger stormwater management system, which may also include other infrastructure such as culverts, channels, and detention ponds. Proper maintenance of catch basins is essential to ensure they function effectively and prevent clogging or blockages that can lead to flooding and water pollution.
