What to Flush

The toilet is only meant to flush the three P's - pee, poop and paper. Human waste and toilet paper should be the only thing going down the toilet. We should avoid flushing substances or objects that could plug a line or cause backups, and additionally avoid sending large amount of food waste through the disposal. Any of these things could create problems if they enter the sewer system. There are some items that might be labeled as flush-able (wet wipes) or have similar properties to toilet paper (facial tissue) that should not be flushed.

Where Does It Go & What Shouldn't Be Flushed


Ever wonder where it goes? Down the toilet or the drain isn't the end of the line. When you flush the water and unmentionables they go somewhere. That somewhere is the Blackfoot Wastewater Treatment Plant. Some things should never be flushed or sent down the drain because they cause problems with our ability to treat waste, or pass through into the environment. View a chart of familiar chemicals and how to dispose of them. Do not use your toilet as a trash can.

  • Antifreeze
