Questions

Grease Trap Sizing and FOG Permit: what people ask

Which fixtures must drain to a grease interceptor?

Under the 2024 IPC, fixtures with grease-laden waste in food prep areas: pot sinks, prerinse sinks, soup kettles, wok stations, floor drains or sinks kettles drain into, automatic hood wash units and dishwashers without prerinse sinks. Only grease-bearing fixtures should drain to it.

How is a grease interceptor sized?

Under the 2024 IPC, hydromechanical interceptors and automatic grease removal devices are sized to standards such as ASME A112.14.3 or PDI G101. A gravity interceptor's capacity is the peak drain flow in gallons per minute times a 30-minute retention time.

Why does the city regulate restaurant grease?

Federal pretreatment rules bar solid or viscous pollutants that obstruct sewer flow, and EPA's report to Congress found grease the most common cause (47%) of reported sewer blockages. Sewer utilities use FOG programs and local limits to control it.
