Sewer Program

Fats, Oils & Grease (FOG) Program

Why fats, oils and grease damage the sewer system — and how to dispose of them safely at home and in commercial kitchens.

Residential cooking fats, oil and grease

Fats, oils and grease being poured into a kitchen sink — the practice the FOG program discourages.

Fats, cooking oils, and grease (FOG) can coat and clog pipes and cause sewer lines to back up into homes. Sewer blockages can be a direct result of fats, oils, and grease (FOG) that you may be unknowingly discharging into the sewer system.

"FOG" can also cause blockages further down sewer lines, creating system overflows as well as disrupting wastewater treatment processes with detrimental results. These blockages are a serious problem that can lead to a hazardous sewage spill. The blockages can be caused by a buildup of FOG that creates a clog in the sewer pipe.

To prevent these problems, we encourage you to dispose of these cooking by-products safely. Here are some alternative disposal suggestions that will reduce your impact on Bear Valley's wastewater infrastructure.

How to properly dispose of fats, oils and grease

Your help is needed to stop these blockages from occurring. In order to stop sewer blockages, please properly dispose of fats, oils, and grease by following these simple instructions:

  • Never pour fats, oils, and grease down the sink or garbage disposal.
  • Before washing, scrape and dry-wipe pots, pans, and dishes with a paper towel and dispose of it in the trash.
  • Use the grease can and plastic liners provided to collect all your excess fats, oils, and grease.
  • Place the plastic liner inside your grease can.
  • Cool fats, oils, and grease and pour into the grease can.
  • Mix fats, oils, and grease with other absorbent material like paper towels, kitty litter, or coffee grounds.
  • Once the grease can is full, remove and tightly secure the liner. Place it in the trash along with other absorbent material like paper towels, kitty litter, or coffee grounds.

The removal of a grease blockage and the cleanup associated with a sewage spill is very expensive and may result in liability and property damages. Sewage spills also harm the environment and cause trail closures.

Thank you for your help in preventing sewer blockages and spills.

Why are fats, oils and grease a problem for the sewer system?

FOG coats and clogs pipes and can cause sewer lines to back up into homes. It can also create blockages further down the line, causing system overflows and disrupting the wastewater treatment process — leading to hazardous, expensive sewage spills.

How should I dispose of cooking fats, oils and grease at home?

Never pour FOG down the sink or garbage disposal. Before washing, scrape and dry-wipe pots, pans and dishes with a paper towel into the trash. Cool excess FOG and pour it into a lined grease can, mixing it with absorbent material like paper towels, kitty litter or coffee grounds, then secure the liner and place it in the trash.

What happens if grease causes a blockage?

Removing a grease blockage and cleaning up the resulting sewage spill is very expensive and may result in liability and property damages. Sewage spills also harm the environment and can cause trail closures.
