Sewer System Management Plan (SSMP)
Wastewater Management and Regulatory Compliance
The City of Rolling Hills Estates owns its wastewater collection system, which is operated and maintained by the Consolidated Sewer Maintenance District (CSMD) of Los Angeles County. To meet updated state safety standards, the City has modernized its management protocols and local laws.
Key Regulatory Updates
- State Compliance: The City has updated its Sanitary Sewer Management Plan (SSMP) to comply with the State Water Resources Control Board’s 2022 General Order.
- Operational Partnership: While the CSMD manages daily operations and emergency responses, the City remains legally responsible for ensuring the system meets all regulatory requirements.
- Municipal Code Changes: Chapter 13.08 of the Municipal Code has been amended to provide stronger enforcement for Fats, Oils, and Grease (FOG) programs and private sewer lateral inspections.
- Infrastructure Resilience: The new SSMP includes enhanced mapping and climate change resiliency planning tailored specifically to the City's local infrastructure.
Future Oversight
In accordance with state law, the SSMP will be audited every three years and updated at least every six years to ensure continued protection of public health and the environment. The current 2026 update remains valid through May 2032, unless significant program changes are required by the state.

Stop the Clog - Trash the FOG!
Fats, Oils and Grease (FOG)
Keep fats, oils and grease (FOG) out of sewer lines to prevent sewer backups which is a headache for property owners as well as a health hazard that could trigger a beach closure if it reaches the storm drain.
Butter, lard, and vegetable shortening are liquid at cooking temperatures but when poured down the drain they congeal in the sewage pipes causing sewer blockages. Even vegetable oil that is liquid at room temperature will coat the lining of sewer lines and cause buildup which leads to clogs.
Every cook, whether in a home or restaurant, can follow these guidelines to prevent sewer backups:
- Scrape/pour FOG into a sealed container and place in the trash, never down the drain.
- Before washing greasy pots and pans, dry wipe with paper towels to absorb excess FOG and then throw the oily paper towels in the trash. (Do not launder oily dish rags because oily residues left after washing can catch fire in dryers).
- Dispose of coffee grounds—which are very oily—in the trash, or better yet, put them in the compost or worm bin.
- But don’t place meat/poultry/fish fats or grease in compost piles—this attracts rodents!
- Fibrous fruit and vegetable waste also contribute to sewer backups—minimize the use of garbage disposals, instead compost or dispose these in the trash.
