Keep Your Sewer Lean by Not Putting Fats, Oils, and Greases down Your Drain
Fats, Oils, and Greases aren't good for your health or sewers!
Sewer overflows and backups can cause health hazards, harm the environment and damage your home. We are finding grease is a common culprit in blocking sewer pipes and causing overflows and sewer backups. Grease gets into the sewer from household drains and poorly maintained grease interceptors at restaurants or other businesses.
Grease and water don't mix…especially in a sewer system!! Having a sewer back-up in your home or business can be a troublesome event! How can customers prevent these events from happening? Be sure to properly dispose of cooking grease. Grease is the number #1 cause of sewer blockages in homes.
Grease (including fats and oils) commonly is the byproduct from frying and cooking using vegetable oil, butter, margarine, lard, and shortening. Grease also includes meat fats, food scraps, baking goods, gravy, sauces, mayonnaise, salad dressings, and even dairy products.
Grease often is washed down the drain in the kitchen where it will stick to the insides of the sewer pipes on your property and in the streets. The grease then over time will build up and block the entire sewer pipe. Avoid pouring cooking oil or other grease down the drain. Instead, pour grease into a heat-resistant container, let it cool, and throw it in the garbage.
Keep in mind that your garbage disposal does not prevent grease from building up in your plumbing system. Garbage disposals only shred solid material into smaller pieces. Your dishwasher removes grease from your kitchenware but does not get rid of the grease. Dish detergents don't get rid of grease either. The grease still enters your plumbing system with shredded solid material which can clog your pipes. Also, rinsing or flushing with hot water doesn't dissolve grease but could just push the grease farther down your sewer lines.
Grease build up can cause the following:
• Raw sewage overflowing in your home, yards, streets, etc.
• An expensive and unpleasant cleanup that often must be paid for by the homeowner.
• Potential contact with untreated sewage which could cause illness.
As a homeowner, you can help solve the grease problem by keeping it out of your sewer system through the following practices:
• Never pour grease down sink drains or into toilets.
• Collect cooking grease in a container and dispose of it in the trash.
• Scrape grease and food scraps from trays, plates, pots, pans, utensils, grills, and cooking surfaces into the trash.
• Keep strainers in your drains to catch food scraps and other solids. Empty the strainer into the trash.
• Do not use your garbage disposal to shred solid material.
Please do your part to keep your sewer system grease free!
