Sewer Do's and Don'ts

what to flush



  • Only flush the 3 P's - Pee, Poop, and (toilet) Paper!

  • Place cooled fats, oils, and grease (FOG) into a compostable bag and toss it into your Organics Cart OR save up FOG in a sturdy container and take it to the OCC Recycling Center, located on Adams Avenue between Harbor Boulevard and Fairview Road in Costa Mesa.

  • Wipe down greasy pots and pans with a paper towel prior to washing in the sink or dishwasher. Soiled paper towels can be placed in your Mixed Waste Cart.

  • Place a wastebasket in the bathroom to dispose of items like diapers, wipes, and personal hygiene products that should never be flushed down the toilet.

  • Use drain strainers for all sink, tub, and shower drains. Empty any food waste collected in your sink into the Organics Cart, while any other collected materials can go into your Mixed Waste Cart.

  • Use the manufacturer's recommended amount of detergent for washing in the dishwasher or washing machine. When detergents enter the sewer system, they can hold large amounts of FOG in suspension, making the process of cleaning and treating wastewater more difficult and costly!

  • Do not pour fats, oils, and grease (FOG) down the drain. This causes build-up in your pipes that can lead to costly damages, sewer backups, and sewer overflows!

  • Do not use the toilet as a garbage can! Only flush the 3 P's - Pee, Poop, and (toilet) Paper.

  • Do not use your sink as a garbage can! Food scraps should be placed in your Organics Cart, so that they can be recycled. Placing food in your sink's garbage disposal can cause clogs and food waste often attracts pests like cockroaches to your home's pipes.
