Oil & Grease Management Program

The discharge of animal or vegetable fat, oil and grease (FOG) into the sanitary sewer has resulted in sewer line clogs, sewer lift station failures, and wastewater treatment plant problems.  In response, Marion Utilities initiated a program to reduce the amount of oil and grease being discharged to the sewer system.

Marion Utilities has a Program Guidance that details our approach to managing the problems associated with FOG.  We also have a list of Best management Practices and instructions for sizing grease traps and interceptors.

New installation?

Grease traps should be installed in accordance with Indiana Plumbing Code requirements.  Grease interceptors should be installed in accordance with the Uniform Plumbing Code requirements.

Individuals can help by scraping all fat, oil, or grease from plates, pots, or pans into a plastic jar with a screw on lid and disposing with your trash.  Fryer oil also needs to be put in a sealable container and disposed in the trash.    

Restaurants and other food service establishments can follow Best Management Practices and install and maintain grease traps or interceptors.
