The Storm Drain Division is responsible to operate and maintain the Storm Water collection system, catch basins, drainage basins, pumping stations and force mains. There are three pump stations, three fore bays, plus numerous catch basins connected to about 12 miles of storm drain mains owned by the City. Additionally, there are 11 miles of storm drains, one large pump station on Center Street and a pump station at Standard Street and El Segundo Boulevard, which is owned, operated and maintained by the Los Angeles County Public Works Department.

Personnel in the Wastewater Division devote at least 20% of their time doing preventive maintenance, repairs and functional checks as needed. Each pump station is functionally checked and operated at least once a week. Once a year each pump station is electrically and mechanically checked out in detail by outside contract.

The National Pollution Discharge Elimination System (N.P.D.E.S.) and the City's Program as a Co-Permittee under the Storm Water Permit have been reviewed in detail. Required Best Management Practices (BMPs) and programs are in place.

Maintenance Workers, Leadworkers and Supervisors respond to emergency service and rain detail calls 24 hours per day. Wastewater and Water Supervisors oversee the rain detail crews.
