What's the Problem with Fats, Oils & Grease (FOG)?

FOG is a problem for the drainage pipes in your home and in businesses. Most foods and many drinks contain FOG. When these are put into the sewer, the FOG attaches to the sides of sewer pipes, reducing the flow. This can cause raw sewage to back up into your home or business, resulting in extensive building and property damage for you or your neighbors. FOG

That is bad for human health, bad for your pocketbook, and bad for the environment. Causing a blockage of a public sewer system is also a violation of the federal Clean Water Act, State and local laws. The result for you may be an expensive visit from a plumber, insurance claims, and penalties for damage to the public sewer system.

The good news is that you can do much to prevent the buildup of FOG in pipes, both yours and the City’s. The City of Redmond thus manages a FOG control program to help keep FOG out of the sewer.
