Fats, Oils & Grease Campaign

Drain Clogged with Grease in Comparison to a Clean DrainCooking fat, oils and grease are very harmful to the City sewer system. They can build up in the sewer pipes over time, clogging the lines and causing blockages and sewer backups into homes resulting in an unpleasant mess that can cost hundreds and sometimes thousands of dollars to clean up. Who pays? You do, through higher utility bills.

Tips

Please help us prevent these problems by doing the following:

  • Do pour cooled grease into disposable containers and into the garbage
  • Do recycle cooking oil and grease for free at Department of Water and Wastewater Resources
  • Do use a paper towel to wipe away residual grease or oil on dishes, pots and pans before washing them
  • Don’t  use hot water and soap to wash grease down the drain, because it will cool and harden in the sewer line
  • Don’t pour cooking oil, grease or greasy food down the drain

Where to Take Your Cooking Oil / Grease

Daly City residents can recycle their used cooking oil and grease for free at the Wastewater Treatment Plant, located at:
153 Lake Merced Boulevard
Daly City, CA 94015

The Department of Water and Wastewater Resources has procured a 247-gallon recycling station, where residents can dispose of their used cooking oil and grease instead of washing it down the sink.
