Fats, Oils & Grease

Fats, Oils & Grease Management Program

The City of Troy routinely monitors the Fats, Oils, and Grease (FOG) entering the sanitary sewer lines. One of our biggest challenges in the Troy Water and Sewer Division is our ongoing effort to keep the pipes clear of FOG. Our newly implemented FOG Management Program will assist us in complying with Environmental Protection Agency (EPA) regulations and decreasing blockages within our shared sewer lines. These FOG blockages could potentially lead to more serious issues such as sewage spills, manhole overflows, or sewage backups in homes or businesses.

When FOG cools in the sewer lines, it solidifies and sticks to the insides of the pipes, trapping food particles and other debris. Large amounts of FOG in the wastewater cause trouble in the collection systems, decreasing pipe capacity and, therefore, requiring that piping systems be cleaned more often and/or piping be replaced sooner than otherwise expected. FOG also hampers effective treatment at the wastewater treatment plant. Although all of these issues can be caused by FOG, it can be managed effectively to minimize adverse impacts on municipal wastewater systems and the environment.
