What is a Catch Basin?

A catch basin is a curbside receptacle whose function is to convey water from streets and other impervious surfaces into the storm drainage system. The design of this drainage structure includes a sump and hood that captures and temporarily stores some pollutants such as oils and sediment. Maintenance to clean out the sump removes the stored pollutants and prevents them from washing further into the storm drain system and into receiving waters such as the West River and Pratt Pond.
