If you're cooking, you'll more than like have a lot leftover grease, oils and fat. City officials want residents to toss these materials in the trash, and not down the drain. Otherwise, the grease can cause some big problems for the city's sewer lines.
"Our pipes don't handle grease well," City of Midland Utilities Director Stuart Purvis told Big 2. "No sewer system does. It will tend to, as it gets cool in the ground, it'll get up in the pipes and cause clogs over time. So we just ask everybody that has those things, at anytime, frying or cooking anything in grease or oils to please, don't put those down the drain."
If you're done cooking, you should all that grease in the trash. You can also place a strainer over the drain in your sink when your rinsing dishes to avoid clogged pipes.
