Sewer F.O.G.

The sewer and wastewater systems are essential components of Suisun City’s health and safety infrastructure.

While these systems do an excellent job of removing unwanted wastes from homes and businesses, there are some materials people often put down their drains that clog or damage their sewer laterals and the public sewer mains.  These materials are collectively referred to as F.O.G. – Fats, Oils and Grease.

F.O.G. Basics

FOG InfoFats, oils and grease are the components of our diet that make food extra tasty and that doctors want most people to avoid. You can add plumbers and sewer system operators to the list of folks who would prefer you minimize F.O.G.

What is F.O.G.? Here as some common items:

  • Cooking oils
  • Lard
  • Butter
  • Margarine
  • Meat fats
  • Peanut Butter
  • Sauces
  • Salad dressings
  • Dairy products
  • Fatty foods

When fats, oils and grease (F.O.G.) are poured down the drain, they solidify and adhere to the inside of the pipes, laterals and mains.  Running either hot or cold water down the drain with F.O.G. doesn’t help prevent this buildup from occurring.

When you couple F.O.G. inside your pipes with the items often put through garbage disposals, you begin to form a potential sewer clog. Particularly harmful food items are rice, noodles, fruits, vegetables, egg shells and coffee grounds – all of which can be composted instead.

Over time, the F.O.G. material combined with the food waste can form an actual plug in household or business pipes, sewer laterals and even move down into public sewer mains.  The U.S. Environmental Protection Agency estimates that nearly 50% of all sewer overflows are caused by F.O.G.

Prevent F.O.G. Problems

Prevent sewer F.O.G. from damaging your drains, sewer laterals and the public sewer main by putting cool fats, oils and grease into sealed containers and placing it in the residual garbage container collected by Republic Services / Solano Garbage.

If you have large quantities of used cooking oil, contact Republic Services directly about turning it in for recycling.
