Fats, Oils, & Grease Program

Fats, Oils, and Grease (FOG) Program

Read our FOG flyer here.

In an ongoing effort to curb sanitary sewer overflows and maintain our low water and sewer rates in the City of Mount Holly, we ask you to please follow a few simple steps to help us prevent sanitary sewer overflows.

As we are cooking our favorite family recipes rarely do we think about what happens to the Fats, Oils and Greases the food has produced. Most of the time we wash it off of our cookware, and it goes down the sink drain and forgotten about. 50-75% of all sanitary sewer overflows are related to FOG build up in the sewer collection system.

Once an overflow is identified and reported to the City, the City will send out its workers to unclog the sewer main, evaluate the cause and estimate the number of gallons overflowed. The City is responsible for reporting this information to the state authorities. Once the state has been notified they will assess the overflow and issue fines to the City accordingly.

WHAT IS FOG?
Organic polar compounds derived from animal and/or plant sources that contain multiple carbon chain triglyceride molecules.

WHERE IS FOG GENERATED?
FOG is generated in every kitchen when we cook our favorite meals.

HOW DO WE PREVENT FOG FROM REACHING THE CITY SEWER MAINS?
Dry cleanup is the single most effective means of FOG prevention. After every meal, we cook in our home once the cookware is cooled to a safe temperature, pour any excessive grease into a non-recyclable container. Then use an absorbent cloth to wipe off all of our cookware with. Once you have finished those two steps then hand wash and/or put the cookware in the dishwasher.

DID YOU KNOW?
Residents can help prevent pipe blockages and sewer overflows by keeping grease out of the sewer system. Sewer backups can cause damage to homes, health hazards and threaten the environment. Sewer pipes blocked by grease are an increasingly common cause of overflows.

Where does grease come from?
Fats, Oils, and Grease are a natural consequence of cooking and can also occur naturally in many foods. Grease is the common term for animal fats and vegetable oils. It can be found in such items as:
• Meat fats
• Lard
• Butter and margarine
• Cooking oil
• Shortening

What are the grease issues?
Grease is frequently poured down the sink drain because the warm oils are liquid and can be poured. It may not appear to be harmful but as the liquid cools, the grease solidifies and causes buildup inside the pipes, becoming a hardened mass. The buildup restricts the
flow of sewage and clogs the pipes.

The implications can be:
• Food scraps
• Raw sewage backing up into your home.
• Reduce the call for a plumber.
• An unpleasant and expensive cleanup at your expense.
• Raw sewage overflowing into parks, yards and streets.
• Potential contact with disease-causing organisms.
• Increased cost for local sewer departments, which causes higher sewer bills for customers

What can you do?
The easiest thing you can do is keep grease out of the sewer system in the first place.
• Never pour grease down the sink or into the toilet
• Scrape grease and food scraps into a disposable container or place in a trash can (after cooling).
• Do not put food scraps down the garbage disposal. These units only shred solid material into smaller pieces and not prevent grease from going down the drain.
• Use a strainer in the sink to catch food scraps and other solids.
