Only Flush the Three Ps#

Only Flush the Three Ps

With concerns about COVID-19, there is increased use of disinfecting wipes and other products like tissues, paper towels or napkins. Only flush the three Ps: pee, poo and toilet paper. Otherwise, throw it out.

Trash It. Don't Flush It.#

Toilet paper dissolved in water after 15 minutes and wipes undissolved in water after two weeks.

On the left, the toilet paper is almost completely dissolved after only 15 minutes. On the right, the “flushable” wipes are still completely intact after two months.

Besides human waste, the only thing that should be flushed is toilet paper. Even if a product claims to be “flushable,” it can cause problems in our sanitary sewer system, potentially leading to a blocked sewer line, property damage and extra expenses for repairs.

The following items do not break down. Put these items in the trash. Do not recycle them. 

  • Wipes (even flushable)
  • Paper towels
  • Trash
  • Cotton Balls
  • Feminine hygiene products
  • Condoms
  • Dental floss
  • Cotton swabs
  • Hair
  • Cigarette butts
  • Facial tissues
  • Diapers
  • Makeup remover pads
  • Cat litter

Keep Fats, Oils and Grease (FOG) Out of Your Drain#

Because the pipes leaving our homes all lead to the same place, we need to be mindful of what we are putting down the sink, too. Fats, oils and grease (FOG) can clog the pipes in your home and in our wastewater (sanitary sewer) system. When FOG goes down a sink drain, it is not broken down by the garbage disposal. Instead, it cools in the wastewater system and sticks to the inside of the pipes, creating FOG buildup. This buildup can lead to sewer blockages that send untreated wastewater backwards – out of manholes or back into your house or your neighbor's house.

You can help prevent FOG from causing backups and harming our sewer system by disposing of your used food waste responsibly. Please pour cooled FOG in a container and throw it away.

Water Efficient Fixtureshighlight_off


Many homes are using water efficient faucets in kitchens and bathrooms. If your home is equipped with these, you’re using less water – great job! It’s important to be aware that keeping fats, oils and grease (FOG) out of your plumbing is key to ensuring your sewer line and our community’s wastewater system operates properly. Click here to learn more about how to properly dispose of FOG.


Water efficient toilets are better for the environment and your pocketbook, saving you money on your water and wastewater bill. In fact, to encourage more residents to upgrade to a toilet that uses less water, Fort Collins Utilities offers rebates for qualifying models, in addition to other fixtures. Saving water improves our community's resilience to drought and other factors.

Only flush the three Ps (pee, poo, and toilet paper) to ensure continued performance in your sewer line and the community's wastewater system. High efficiency fixtures, such as toilets, mean less water flows to the sewer. Adopting good disposal practices is key to minimizing blockages and other issues.
