Don't flush trash down the toilet! Learn about how you can help prevent pollution and keep water clean.

Don't flush trash

Use a trash can instead of the toilet to dispose of all wipes, hygiene products, tissues and other items that don’t break down.

Even if the label says “flushable”, wipes should never be flushed! Trash can build up in the sewer system and cause overflows, which damages property, hurts the environment, and can make people sick.

Last year, King County’s Wastewater Treatment Division spent over $120,000 just to take the wipes, tampons, and other trash that came into our treatment plants to a landfill. That’s enough trash to fill two semi-trucks every week! Plus, clogged pipes and jammed equipment means increased costs in operation and maintenance.

Putting the wrong things down sinks and toilets might also cause expensive plumbing problems in your home or business. Toilet paper and human waste are the only things that should be flushed!

Minnesota Pollution Control Agency demonstrates how toilet paper breaks down in water, but wipes don’t.



Info for those on septic systems : Household pipes and septic tanks are only designed to handle toilet paper.

Don't dump grease

  • Use screens to keep hair, fruit stickers and other stuff out of drains and pipes.
  • Scrape out greasy bowls, pots, and pans before washing.
  • Keep fatty foods and meats out of the garbage disposal, and put cooled, solidified grease in the trash.

What happens when grease is washed down the drain?

When grease is washed down the drain, it sticks to the inside of sewer pipes (both on your property and in the streets). Over time, it builds up and can block an entire pipe. Garbage disposals do not keep grease out of the pipes, they only shred it into smaller pieces.

The results of a grease-blocked sewer pipe can be:

  • Sewage overflows in your home or your neighbor's home
  • The average cleanup cost is about $3,000
  • Possible contact with disease-causing organisms
  • An increase in operation and maintenance costs by the local sewer district and King County, which causes higher sewer bills for customers

Visit King County Solid Waste's What do I do with...? website for information about safely disposing of fats, oils, and grease.

Don't flush medications or chemicals

Don’t put unwanted medications down the toilet or sink. Worried about keeping discarded meds away from kids or pets? Many pharmacies across King County now take back expired or unwanted medications for safe disposal.

Got paint, pesticides and other household chemicals you no longer need or want? King County’s Wastemobile and Household Hazardous Waste Drop-off Sites are a much safer alternative to putting these things down the drain or in the trash.

A toilet with a trash can next to it. Only toilet paper goes in the toilet. Everything else (even if it is labeled flushable, such as wipes, tissues, paper towels and diapers) goes in the trash. Download pdf (EnglishEspañol)

Put used masks and gloves in the trash

Put used gloves, masks, and wipes in the trash; they are a health and wildlife hazard.

Clogged pump

Wipes, even when labeled “flushable”, can clog sewer equipment – and the pipes in your home.

Cleanings from the digester - full of trash

Nothing but toilet paper! All other items should go in the trash including tissue, wipes, paper towels, hygiene products, ear swabs, dental floss, etc.

Grease in sewer

Grease going down the drain can cause serious problems in our sewers and your house drains and pipes.
