The next time you’re cleaning up after dinner, pay attention to what’s going down the drain. Sure, we all know not to dump bacon grease. But there are several other foods that can also cause serious plumbing problems and harm the environment.

Fats, oils, and grease—or FOG—is any food waste that should not go down the drain. This includes cooking oil, pan drippings, gravy, bacon grease, lard, shortening, butter, margarine, salad dressings, mayonnaise, creams, and sauces. Even non-greasy food scraps can clog your home’s wastewater lines, so you should avoid putting food of any kind down your drain.
Food buildup restricts the flow in pipes and can cause untreated wastewater to back up into homes and businesses, resulting in high costs for cleanup and restoration. In extreme cases, manholes can overflow in neighborhoods and contaminate local waters, including drinking water.
Communities spend billions of dollars every year unclogging or replacing blocked pipes, repairing pump stations, and cleaning up costly and illegal wastewater spills–all of which can affect local wastewater rates. So, keeping food waste out of the sewer system helps everyone.
Luckily, there are simple steps everyone can take to avoid costly clogs, protect public health, and keep our water clean.
