Fats, Oils & Grease Program

FOR COMMERCIAL CUSTOMERS

IRWD's FOG Program review of Food Service Establishment plans is required to ensure that the new (or modified) facility meets current FOG Program rules and regulations.

IRWD maintains the public sewer system serving your business and is required under state law to implement a comprehensive fats, oils and grease (FOG) control program to prevent the discharge of FOG into the sewer system. As a commercial customer of IRWD, you can help protect the environment by preventing sewage spills. 

Never pour fats, oils or grease down a sink or other drain.

About IRWD's FOG Program

This multilingual public education program is in response to the Santa Ana Regional Water Quality Control Board's enactment of Order No. R8-2002-0014, which calls for a Sewer System Management Plan. A key element of the plan is a public education program designed to inform the general public and food service establishments such as restaurants about proper disposal of fats, oils and grease. Education materials are available in English, Mandarin Chinese, Korean, Spanish and Vietnamese.

Local businesses and professionals can be recognized by Irvine Ranch Water District for demonstrating exceptional sewer maintenance practices by participating in the District's Sewer Savvy program.

The program is open to plumbers, property managers, restaurants and other Food Service Establishments, and other companies that demonstrate best management practices that keep drains, laterals and sewer lines trouble-free.
