What is F.O.G.?

F.O.G. stands for Fats, Oils, and Grease and is commonly found in household kitchens and restaurants. Examples of F.O.G. are meat fats, lard, cooking oil, shortening, butter and margarine, food scraps, baked goods, sauces, soups and dairy products.

What is the problem with F.O.G.?

When F.O.G. is poured down the drain, it solidifies and sticks to the insides of sewer pipes, both on your property and in the City’s collection system, which overtime causes obstructions and eventually blockages. Once these blockages are formed, they can cause sanitary sewer overflows. Sewer overflows can cause raw sewage to enter the streets, storm drains, streams, businesses, yards and even homes. Sanitary sewer overflows pose a risk to public health, adversely affect aquatic life, and are costly to clean up.

Manage and Dispose of F.O.G. Properly

  • Don’t pour Fats, Oils, and Grease (F.O.G.) down your sink drains or toilets. They will clog your pipes and sewer/septic systems.
  • FOR SMALL AMOUNTS OF F.O.G., scrape out or use paper towels to wipe your pans, then place the F.O.G. or soiled paper towels in the Food Scraps side of your gray GARBAGE/FOOD SCRAPS split cart.
  • FOR LARGE AMOUNTS OF F.O.G., use the curbside cooking oil collection program! Residents may place up to two (2) gallons of used cooking oil (in accepted containers) at the curb for collection each week. Oil containers can be requested from Milpitas Sanitation.
  • FOR EVEN LARGER AMOUNTS OF F.O.G., collect cooled oil in a sealable container (no larger than 15 gallons) and take it to a Santa Clara County Household Hazardous Waste Facility. Limits apply. Please visit or call (408) 299-7300 for more information.

F.O.G. Education

In an effort to prevent the introduction of F.O.G. into the City’s sanitary sewer system, the City developed a F.O.G. Program. This program is intended to educate businesses, as well as residents, on the problems associated with F.O.G. and the measures that can be taken to limit or prevent the introduction of fats, oils and grease into the City’s sanitary sewer system.
