Keep Fats, Oils, and Greases Out of the Sewer
When it’s washed down the sink, grease from meat fats, lard, oil, shortening, butter, margarine, food scraps, baked goods, sauces and dairy products sticks to the insides of sewer pipes. Over time it can build up and block an entire pipe on your property or in the street. Moreover home garbage disposals do not keep grease out of the plumbing system. And hot water and products such as detergents that claim to dissolve grease only pass it down the line and cause problems elsewhere. Results can include raw sewage overflowing in your home, the house next door, parks, yards or streets, and potential contact with disease-causing organisms. Sewage overflows resulting from grease in the system can also mean expensive clean-up costs for the involved home or business owners and well as increased operation and maintenance costs for local sewer departments, which leads to higher sewer bills for customers.
You can help prevent sewer overflows by following a few simple suggestions:
- Never pour grease down sink drains or into toilets.
- Scrape grease and food scraps into a can or the trash for disposal or recycling (where available).
- Put baskets or strainers in sink drains to catch food scraps and other solids, and then empty them into the trash.
