Grease Traps

FOG (Fats, Oil, and Grease) Control Program

Fats, Oils and Grease (FOG) are a major issue for the Town’s sewer system. Food service establishments (FSE) are a significant source of FOG due to the amount of grease that is used in cooking and other food preparation. Transportation service establishments (TSE) are also a significant source of oil and grease. When poured down the drain, FOG hardens inside of pipes, constricting wastewater flow and clogging pipes. This can lead to sewer backups into your business. Cleaning clogged pipes and responding to sewer backups is costly to business owners and the Town.

Lyons Municipal Code 13-4-140 requires the installation and maintaince of pretreatment devices in all food and transportation service establishments. The ordinance was passed to protect not only the collections and wastewater treatment systems, but the health, safety and welfare of residents, business owners and the environment. Below are a few basic cleaning requirements of the ordinance:
  • All inline under the sink grease traps must be cleaned a minimum of once a week. 
  • All grease interceptors must be cleaned quarterly at a minimum – more frequently when deemed necessary at time of inspection. 
  • Grease Trap Reporting Form and any applicable documentation must be submitted to the Town of Lyons quarterly, and all pertinent cleaning documentation must be kept on site for a minimum of three (3) years and available for inspection at any time.
