Stop Fats, Oil, & Grease

Fats, oil, and grease (FOG) clog pipes and can cause sewer backups. Sewer backups are a risk to human health and the environment. FOG also creates unnecessary wear on private and public sewer pipes. Help keep FOG out of sewer pipes.

The City provides no-cost FOG kits to Wood Village community members. If you would like a kit, please contact City Hall at (503) 667-6211 or email City Hall.

Household Sewer Sources

Common Sources of FOG from Homes

Do Not

  • Never pour grease down sinks or toilets!
  • Don’t run hot water over dishes, pans, and griddles rinsing oil and grease down the drain
  • Don’t flush any type of wipe down the toilet

Do Dispose of Grease Properly

  • Scrape food waste into your garbage can or compost.
  • Wipe pots and dishes to remove grease before cleaning.
  • Put your FOG in a disposable container, freeze it, then place it in the trash.

Prevent FOG

Food service businesses use grease removal devices to separate FOG from their wastewater. Keeping FOG out of the sewer system helps avoid dangerous sewage spills and costly cleaning.

  • Grease removal devices work best when serviced regularly.
  • Pump-out and service reports sent to the City quarterly meet compliance monitoring and limit business and grease removal device inspections.

Preferred Pumper Program

Most food service businesses hire a pumping company to clean out and maintain their grease removal devices.

Using a service provider from the City’s Preferred Pumper Program is recommended.

Preferred Pumpers meet certain service requirements and send service reports to the City.

Tips to Reduce FOG

  • Scrape solids from cookware and dishes, then dry wipe to remove excess food and grease before washing.
  • Recycle grease and oil.
  • Check grease removal devices often to make sure they are properly pumped and maintained.
  • Never pour grease and oil into sink or floor drains.

Report FOG to the City

Businesses with grease interceptors are responsible for reporting cleanings a minimum of once a year (recommended quarterly) to the City of Wood Village. Either the business or the waste cleaning/hauling service provider may report the cleaning to the City. Businesses should use the Pump-Out Report (PDF) and submit it online using the form below or email the report to email to the City.
