Grease Traps

Over 70% of sewer blockages are caused by fats, oils, and grease (F.O.G.). A well designed and maintained grease trap could be your sewer’s last line of defense.

The Grease Trap’s function is to intercept liquid greasy waste and garbage and retain it for an adequate amount of time, thereby allowing the greasy liquid to cool down. This process, in turn, promotes the separation and coagulation of the grease from the water.  Moreover, the detention time created by the grease trap allows for the separation of garbage from the waste.

Gainey’s manufactures a wide range of traffic and non-traffic rated grease traps – call today for design assistance!
