Fats, Oils, and Grease (FOG) Program

FOG is an acronym for Fats, Oils and Grease that are deposited into the sanitary sewer system. FOG comes from meat fats in cooking and food scraps, cooking oil, shortening, lard, butter and margarine, gravy, and food products such as mayonnaise, salad dressings, sour cream and other foods high in fat. 

The Impact of FOG

FOG poured down kitchen drains accumulates inside sewer pipes. As the FOG builds up, it restricts the flow in the pipe and can cause untreated wastewater to back up into homes and businesses. Manholes can overflow into parks, yards, streets, and storm drains, allowing FOG to contaminate local waters, including drinking water. 

All of this leads to increased costs for residents, businesses, and the Town when it comes to cleanup and restoration. 

Residential Disposal of FOG

Here are all the ways you can help keep FOG from causing problems in our community:


  • Put oil and grease in covered collection containers. Then, schedule a pickup through the Town's Household Hazardous Waste program.
  • Scrape food scraps from dishes into trash cans and garbage bags and dispose of properly. Avoid using your garbage disposal.
  • Remove oil and grease from dishes, pans, fryers, and griddles. Cool first before you skim, scrape, or wipe off excess grease.
  • Prewash dishes and pans with cold water before putting them in the dishwasher.
  • Cover kitchen sink with catch basket and empty into garbage can as needed.
  • Cover floor drain with fine screen and empty into garbage can as needed.


  • DON'T pour oil and grease down the drain.
  • DON'T put food scraps down the drain.
  • DON'T run water over dishes, pans, fryers, and griddles to wash oil and grease down the drain.
  • DON'T rinse off oil and grease with hot water.

Commercial Businesses 

Grease traps or interceptors are required by the Town for all food establishments. Both interceptor and trap location must be approved and located outside the building. A design must be submitted at time of permit application.
