What is a catch basin?

A catch basin is specifically designed to collect debris and sediment from stormwater runoff, making it an essential component of stormwater management systems. Its primary function is to trap sediments, leaves, and other debris carried by rainwater, preventing these materials from clogging downstream drainage systems, which could lead to flooding or water quality issues.

The design of a catch basin usually includes a sump or a reservoir at the bottom that allows heavier particles to settle while allowing the filtered water to flow through an outlet pipe. This way, the system helps maintain efficient water drainage and protects the environment by reducing contaminants that could enter waterways.

In contrast, structures that catch animals, pipes for directing water, and holding tanks for sewage serve entirely different purposes and functionalities, emphasizing the unique role of catch basins in managing stormwater and maintaining drainage systems.
