I. Grease Management Program For Food Service Facilities

The purpose of this program is to minimize the introduction of fats, oils, and greases into the Clayton County Water Authority (CCWA) wastewater collection system. The main components of the program are the proper sizing, installation, and maintenance of grease interceptors. The administrative and inspection requirements of food service facilities are established herein as well.

Low Flow Pre-Rinse Spray Valves Save Water and Energy

Dishwashing in a typical restaurant consumes more than two-thirds of all the water used in the restaurant. Nearly one-half of that water is used by a pre-rinse spray valve to rinse dishes, utensils and pans before placing them in the dishwasher. Low-flow pre-rinse spray valves are designed to decrease the amount of water and energy needed to achieve fast and easy cleaning, saving water and energy for restaurants, schools, hospitals, churches and organizations. Replacing an older, inefficient spray valve with a low-flow 1.6 gallon per minute spray valve can reduce water use by 50 percent.

IV. Prevent Fats, Oils and Greases (FOG) from damaging your home and the environment

Fats, Oils and Greases (known as FOG in the water industry) are not just bad for your arteries and your waistline; they are bad for sewers too. Sewer overflows and backups can cause health hazards, damage home interiors and threaten the environment. An increasingly common cause of overflows is sewer pipes blocked with grease. Grease gets into the sewer from household drains, as well as from poorly maintained grease traps in restaurants and other businesses.

Where does the grease come from? Most of us know grease as the byproduct of cooking. Grease is found in such things as:

  • Meat fats

  • Lard

  • Cooking oil

  • Shortening

  • Butter and margarine

  • Food scraps

  • Baking goods

  • Sauces

  • Dairy products

Too often, grease is washed into the plumbing system, usually through the kitchen sink. Grease sticks to the insides of sewer pipes (both on your property and in the streets).

Over time, the grease can build up and block the entire pipe (as seen in the photo). Home garbage disposals do not keep grease out of the plumbing system. These units only shred solid material into smaller pieces and do not prevent grease from going down the drain. Commercial additives, including detergents, that claim to dissolve grease may pass grease down the line and cause problems in other areas. The results can be:

  • Raw sewage overflowing in your home or your neighbor's home.

  • An expensive and unpleasant cleanup that often must be paid for by you, the homeowner.

  • Raw sewage overflowing into parks, yards and streets.

  • Potential contact with disease-causing organisms.

  • An increase in operation and maintenance costs for the Clayton County Water Authority, which causes higher sewer bills for customers.

What can you do to help? The easiest way to solve the grease problem and help prevent overflows of raw sewage is to keep this material out of the sewer system in the first place. There are several ways to do this.

  • Never pour grease down sink drains or into toilets.

  • Scrape grease and food scraps from trays, plates, pots, pans, utensils and grills and cooking surfaces into a can or the trash for disposal (or recycling where available).

  • Do not put grease down garbage disposals. Put baskets/strainers in sink drains to catch food scraps and other solids, and empty the drain baskets/strainers into the trash for disposals.

  • Speak with your friends and neighbors about the problem of grease in the sewer system and how to keep it out. Call the Clayton County Water Authority at 770.961.2130 if you have any questions.
