Grease Interceptors help Prevent
Sanitary System Overflows (SSO)
This applies to several types of food service establishments such as restaurants, cafés, schools, colleges, universities, medical facilities, assisted living facilities, correctional facilities, malls, stadiums, arenas, convention centers, casinos, etc.
When the sewer system, which conveys wastewater, including human waste, overflows, this event is known as a sanitary sewer overflow (SSO). The EPA’s Report to Congress on sanitary sewer overflows identified that grease is the most common cause of blockages. The National Pretreatment Program provides authority to state and local publicly owned treatment works to reduce or eliminate sanitary sewer overflows. One method of enforcement is effluent quality. The EPA identified an effluent quality of 100 mg/l as a common pretreatment limit.
