A stormwater basin, also known as a sump, is a reservoir that acts as a collection area for storm water overflow. Torrance has several sumps that encompass fairly large areas that can be used to simulate a variety of outdoor venues including open fields, marshes or countryside paths. There are a total of 17 sumps in the City of Torrance, 14 owned and operated by the City of Torrance. 

South Bay cities are required by the Regional Water Quality Control Board of Los Angeles to prevent or treat stormwater with bacteria being discharged to the Santa Monica Bay. Therefore, the City of Torrance maintains stormwater basins in West Torrance to provide natural treatment systems, improve infiltration and groundwater recharge, and provide habitat restoration in these open spaces.
