Pretreatment and Industrial Waste


Fats, Oils, and Grease Management Policy

Fats, Oils, and Grease (FOG) are generated during food preparation. When water is used to clean kitchen fixtures and utensils, FOG is washed down the drain where it cools and separates. The separated FOG accumulates in and can cause blockages in drains, sewer pipes and the collection systems.  FOG clogs damage wastewater infrastructure, including home plumbing.

RWRA’s FOG Management Policy requires Food Service Establishments to properly use grease interceptors to prevent FOG related issues in the sewer system.
