Did you know that fats, oils and grease, sometimes referred to as FOG, are bad not only for your arteries and waistline but for your sewers, too? Just as fats, oils and grease can lead to clogged human arteries, putting fats, oils and grease down your home drain can lead to clogged sewer pipes. These blockages in the sewer pipe may cause sewage to backup into your home, resulting in an expensive and unpleasant cleanup that most often must be paid by you, the homeowner. Blockages may also trigger an overflow or backup of sewage into streets, yards, parks or waterways, creating a public health risk and threat to the environment.
They are byproducts of cooking. For example, meat fats, lard, oil, shortening, butter and margarine, fatty/greasy food scraps, baking goods, sauces, salad dressing, and dairy products are all sources of fats, oils and grease. When washed down the kitchen sink, liquefied fat and grease will solidify and clog pipes, while liquid oils coat the pipes contributing to the blockages.
Do not dispose of any cooking oils or grease down the drain. Prevent sewer backups and overflows by following the guidelines below:
