Frequently Asked Questions

A grease interceptor is a receptacle located between the drain lines and the sanitary sewer lines It separates and collects fats, oils and greases (F.O.G.) from the wastewater to help keep harmful clog-causing debris out of the drain lines and City sewer system

The City of Hamilton, as well as most other municipalities, has imposed a minimum amount of F.O.G. that is acceptable in the wastewater leaving an establishment It also helps to prevent F.O.G. from plugging up the drains and causing unnecessary damages

The interceptor slows down the water coming from the drains which allows the F.O.G. to cool The water passes over a series of separator baffles that are designed to cause F.O.G. to separate from the wastewater The cooled F.O.G. then rises to the top of the interceptor and accumulates until removed The wastewater is now relieved of 90% or more of F.O.G. and can flow into the sewer system
