Fats, Oils & Grease

Overflows and backups are commonly found to be caused by fats, oil and grease (FOG). Grease gets into the sewer from household drains and neglected grease interceptors at businesses such as restaurants. The grease blocks sewer pipes, causing health hazards and leading to expensive fixes. It also damages the environment. Loudoun Water alone operates and maintains more than 986 miles of water main and 727 miles of sewer main.

FOG includes cooking oils like vegetable or olive oil, butter, margarine, lard, shortening, meat fat, food scraps, bacon grease, baking goods, gravy, sauces, mayonnaise, salad dressings and dairy products. Many plumbers say emergency calls almost double the day after major holidays.

Using the garbage disposal does not alleviate grease from entering your drain and sticking to the sides of your pipes leading from the house to the street. Garbage disposals only shred discards into smaller pieces. Likewise, the dishwasher only cleans dishes, it does not remove grease. Running hot water down the sink with the grease only pushes the grease further down the pipes.

The best way to prevent grease from entering your sewer system is to properly dispose of it away from your drain.

Don’t pour grease down your sink or toilet. Pour used grease in a container and take it out with the trash. Scrape food particles on dishes and cooking utensils into the trash before placing them in the sink or dishwasher. Limit the use of your garbage disposal; place strainers in your drains and empty the catch in the trash.

These simple steps will help reduce overflows and backups, ensuring non-interrupted service of your water and a healthier environment.
