The City of Rolling Hills Estates has developed a comprehensive Sewer System Management Plan (SSMP) in compliance with the State Water Resources Control Board’s Waste Discharge Requirements (WDRs). These requirements were established to address concerns over sanitary sewer overflows (SSOs) and their impact on public health, water quality, and the environment. The SSMP outlines the City’s policies and procedures for the proper operation, maintenance, and management of its sanitary sewer collection system, which is maintained by the Los Angeles County Consolidated Sewer Maintenance District. The plan is structured around 12 key elements aligned with the WDRs and includes proactive goals and actions to minimize SSOs, ensure rapid and effective response when overflows occur, and maintain compliance through regular reporting and staff training. By implementing this SSMP, the City aims to protect public safety and preserve water quality through responsible sewer system management.

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.
