Fats, oils, and grease, also called F.O.G., come from many common foods like butter, oils, meat drippings, and sauces. These substances might look harmless, but they can cause real problems when they are washed down the sink.
F.O.G. does not mix with water. Instead, it sticks to the inside of pipes and becomes thick and hard as it cools. Over time, this buildup can block pipes in homes and in our sewer system. Even worse, these clogs can lead to slow drains, bad smells, sewage backups, and expensive repairs.
A national study found that more than half of the F.O.G. found in sewer systems comes from single family homes. Much of it is poured into sinks or washed down garbage disposals.
When F.O.G. enters pipes, it mixes with other items like food scraps, or hair and can form a thick blockage. These blockages can cause wastewater to back up into our streets or homes. This is why simple kitchen habits make a big difference in keeping our sewer system working properly.
These small steps protect your plumbing at home and help us reduce sewer clogs and costly repairs:
