Wastewater Service - Grease Control Program

Grease is one of the primary causes of stoppages, backups, and overflows in a wastewater collection system. Grease buildup in the sewers also causes restrictions and capacity problems. Newport Utilities’ goal is to improve sewer service by reducing the impact of grease. This goal will be achieved through two related programs:

Grease Control Program

Newport Utilities’ “source control” program, through which Food Service Facilities (FSF's) are required to capture and properly dispose of the grease generated by their operation. The focus of the manual below is the Grease Control Program, including the proper sizing, installation, and maintenance of grease trap/interceptor. The administrative and inspection requirements are established as well. Through the cooperative efforts of FSF's with Newport Utilities, the goal of improved sewer service through proper grease control can be achieved.
