The State Water Resources Control Board
(SWRCB) adopted Order Number 2006-0003-DWQ, the Sanitary Sewer
Systems Waste Discharge Requirements (WDRs), which requires all
federal and state agencies, municipalities, counties, districts and
other public entities that own or operate a wastewater collection
system greater than one mile in length to develop and implement a
system specific Sewer System Management Plan (SSMP). The SSMP
documents how an agency manages its wastewater collection system.
SSMP provides a set of regulations that
help reduce unintentional release of raw sewage before it is
treated; this is known as a sanitary sewage overflow (SSO). SSOs can
contaminate our waters, causing serious water quality problems, and
back-up into homes, causing property damage and threatening public
health. Common causes of SSOs are blockages, tree roots, land
movement and damaged infrastructure.
To report a sewer overflow, please
contact, Los Angeles County Consolidated Sewer Maintenance District
For information on City of Calabasas
SSMP, please contact the Public Works Department at (818) 224-1600.
