Grease Interceptor Information
If you run a business that produces and disposes of fat, oil or grease (FOGs), like a restaurant, food processing establishment, hospital or day care and senior center, you need a grease interceptor. This system stops FOGs from clogging the city's sewer lines. It separates FOGs from wastewater.
Grease interceptors need regular cleaning to work well. The Department of Environmental Protection (DEP) checks to make sure businesses have and maintain these systems. Teaching your employees about proper grease handling can help keep your business in compliance.
Find more details on DEP's grease rules and best practices.
Installation and maintenance
- Only licensed plumbers should install grease interceptors.
- Plumbers can help you choose the right size for your business.
- For help, plumbers and business owners can contact the DEP's Bureau of Wastewater Treatment, Compliance Engineering Section.
Reducing FOGs impact
The DEP wants businesses to reduce the impact of FOGs on the sewer system. The DEP provides signs to remind employees about FOGs reduction. Both grease from interceptors and waste cooking oil can be recycled. Licensed waste haulers or private carters can collect and dispose of it.
Types of grease
There are two types of grease that waste haulers can pick up:
- Yellow grease: used cooking oil, often picked up for free because it can be recycled.
- Brown grease: from grease traps, more solid and can be disposed of with solid waste or by hiring a private hauler.
Check with a licensed waste hauler for their rates and fees.
