Rockport FOG Program

What is FOG?

FOG is Fat, Oil, and Grease. It comes from food preparation and from food products, such as:

  • Meat
  • Fats, lard, cooking oil, shortening
  • Butter & margarine
  • Food scraps
  • Baked goods
  • Sauces
  • Dairy products


When FOG gets into the sewer lines it can cause blockages and backups. This can cause damage to

homes and businesses, as well as create a public health problem.


  • DO NOT dump fats, oil, and grease down the sink or floor drain or into toilets
  • DO NOT rinse dishes in hot water (more than 140oF) – this may “melt” grease, but it will reform in the sewer main
  • DO NOT put FOG sources (e.g. meats, fried foods) down the garbage disposal
  • DO NOT use additives that “degrease” – many of these temporarily break up FOG, and it can reform in the sewer main
  • DO NOT hose down floors and work areas into floor drains that do not have grease traps
  • DO regularly clean and maintain grease traps/interceptors
  • DO collect FOG in containers and dispose of in the trash
  • DO scrape all food and FOG from plates, pots, and pans prior to washing and dispose of in trash
  • DO dry wipe pots and pans
  • DO use less FOG in cooking and baking
