Controlling fats, oils, and grease in the City collection system is an important component of an overall plan to minimize sanitary sewer overflows.
Grease often accumulates and solidifies inside the pipes and restricts free flow of raw sewage on its way to the wastewater treatment plant, which overflows the system, causing sewage to overflow into the streets, yards, and storm ditches.
Reducing Grease from Residential Kitchens
Residents can prevent grease from entering the sewer system by doing the following:
Collect grease in containers (i.e., used cans, glass jars, etc.)
Dispose of hardened grease with regular household trash
Reducing Commercial Grease
