Sewer - Fats, Oils, and Grease

Fat, oil and grease in sewer pipes, referred to as FOG, create pollution problems in many communities. FOG enters sewer pipes through restaurant, residential and commercial sink drains. Once in the sewer, FOG sticks to the pipe and thickens. FOG can build up and eventually block the entire pipe. Blockages in sewer pipes can send sewage backward – out of manholes into streets and rivers, or up floor drains in homes. These sewage overflows pollute the environment.

Preventing sewer backups from FOG blockages saves residents money and protects the environment. When sewer pipes on private property back up, the homeowner is responsible for the cleanup. For example, if a resident regularly pours grease down a drain, it will eventually cool, harden and form a blockage in the sewer pipe. Sewage then backs up through floor drains and toilets at the lowest point in the house. A plumber will have to be hired to clean the sewer and possibly repair plumbing inside the home.
