Reducing Fats, Oils, and Grease in Your Community

Information about how to reduce fats, oil, and grease in your community's sewer system.

Fats, oils, and grease (FOG) can cause serious damage to your community’s sewer system. Every year communities spend billions unclogging or repairing pipes.

FOG often clings to materials, such as wipes that have been flushed or roots that have infiltrated the pipes, building up to create a large blockage.

As FOG clogs pipes, the bits of rotting food trapped in the FOG form hydrogen sulfide. The hydrogen sulfide combines with water to form sulfuric acid, which eats the pipes.

The clogs caused by FOG can also cause sanitary sewer overflows, which expose people to raw sewage—a serious health hazard—and are expensive to clean up.

The TCEQ has developed the "Let's Tackle the Grease in This Kitchen" poster, available in English and Spanish.
