Grease Trap and UCO - Grease Trap Service

Grease Trap Service

A grease trap, also known as a grease interceptor, is a passive plumbing control device designed to reduce the amount of fats, oils and greases (FOG) that enter the sanitary sewer collection system. Grease traps work by providing a retention chamber that is designed to slow the drainage flow to permit grease to float, solid material to settle and the “clean” water to exit to the drain/sewer system. Building codes require the installation of grease traps wherever fats, oils and greases could be discharged into the sewer system. Sewer-use bylaws limit the amount of FOG and suspended solids that are permitted to be discharged to the sewer system.
