Grease Control#

Facilities with potential to discharge excessive amounts of grease in their wastewater are required to maintain a grease interceptor. These interceptors help prevent excessive amounts of fats, oils, and grease (FOG) from entering the wastewater collection system which could cause blockages and sewer backups that may endanger public health and pollute our local waterways.

Example Grease Interceptor 

Facilities within the City sanitary sewer service area are required to maintain their grease interceptor in a continuously efficient operating condition. Appropriate maintenance includes complete removal of all contents of the interceptor at a frequency that ensures the unit has adequate capacity for liquid/solid separation.

Utilities operates a grease interceptor inspection program to ensure interceptors are properly maintained. No more than 33% of the capacity of an interceptor's inlet chamber may be occupied by fat, oil, grease and solids. It is the business's responsibility not to exceed this threshold at any time. Food service facilities can reduce the cleaning frequency for their interceptor by following these best management practices.
