FAQ

Q:  What is FOGG, and is it a problem?
A:  FOGG is made up of fat, oil, grease, and grit, and it is a very BIG problem! FOGG does not mix with water because its components are insoluble and have a tendency to separate from a liquid solution. When fat, oil and grease are poured down the drain, they stick to the sewer pipe walls creating layers of buildup that restrict the wastewater flow. This problem requires pipes to be cleaned more frequently, causes pipes to be replaced sooner than expected, and causes blockages that can result in sewer overflows.

Q:  How does fat, oil, grease, and grit (FOGG) create a sewer blockage?
A:  Fat, oil, grease, and grit in a warm, liquid form may appear to be harmless since they flow easily down the drain. However, as the liquid cools, the FOGG solidifies and floats to the top of the other liquid in the sewer pipes. The layer of FOGG sticks to the sewer pipes and over time, the flow of wastewater becomes restricted and can cause a backup or overflow. The gritty particles, including coffee grinds, eggshells, aquarium gravel, grain, rice, seeds, etc. get trapped in the greasy buildup, accelerating the problem rapidly.

Over time, FOGG accumulates in the sewer system in much the same way that cholesterol accumulates in our arteries. As FOGG builds in the pipes, wastewater becomes increasingly restricted. Suddenly, sometimes without warning, a sewer pipe backs up and overflows, similar to a heart attack. The result is a home flooded with sewage, or sewage overflowing in the street, where it flows – untreated – into area waterways.

Q:  What products contain fat, oil, grease, and grit (FOGG)
A:  Fat, oil, grease and grit are natural by-products of the cooking and food preparation process. Common sources include food scraps, meat fats, cooking oils, lard, baked goods, salad dressings, sauces, marinades, dairy products, shortening, butter and margarine, coffee grinds, eggshells, grain, rice, seeds, etc. Anything put through the garbage disposal adds to the buildup.

Q:  What can I do to keep fat, oil, grease, and grit (FOGG) out of the sewer and help prevent a grease related sewer overflow from occurring in my house or on my street?
A:  Everyone plays a role in preventing FOGG from damaging our sewer system. The following easy tips can help prevent a sewer overflow in your home or neighborhood.

  1. Fat, oil, grease, and grit should NEVER be poured down the sink. Sink drains and garbage disposals are not designed to handle these materials properly.
  2. Before washing, scrape and dry wipe pots, pans and dishes with paper towels and dispose of materials in the trash.
  3. Pour fat, oil, grease and grit into a disposable container, such as an empty glass jar or coffee can. Once the liquid has cooled and solidified, secure the lid and place the container in the trash.
  4. Disconnect, or at least minimize use of the garbage disposal to get rid of food scraps. The garbage disposal chops up food into small pieces, but can still cause a blockage in the pipe. Use sink strainers to catch food items, and then empty the strainer into the trash.

Q:  Why is it important to dispose of FOGG properly?
A:  Sewer system maintenance in neighborhoods that experience sewer blockages and backups due to fat, oil, grease, and grit is expensive and can contribute to the amount that customers pay for sewer service. A sewer blockage or backup can also result in expensive repairs to the home.
