Prohibited Waste

What should NOT be flushed down the sewer ?

Sewers are designed to take away used dirty water from sinks, baths, showers, laundries, and toilets.  Flushing away non-flushable items can be dangerous, cause public health problems, and adds to the cost of operating and maintaining your sewers and the treatment plant.

Flushing of toxic or flammable liquids down the sewer is NEVER a good idea. This could be harmful to you, sewer workers, and definitely the environment, as sewage treatment facilities are not designed to process this waste. Take these liquids to a proper recycling or disposal site.

Reminder- cooking grease will solidify in your pipes as soon as it contacts cold water. This will clog the pipes in your house before it even gets to the street sewer !!

Solids – Never flush the following items down the drains or toilets:

  • Unused Medications   see EPA Brochure
  • Diapers, feminine products, bandages, Q-Tips, or cloth of any kind
  • Wipes of any kind – cleaning wipes, baby wipes, etc…
  • Plastic objects
  • Razors and blades
  • Kitty litter
  • Aquarium gravel
  • Seafood shells




Solid items (except medicines) should ALL be carefully disposed of in your trash containers.  Putting trash down the toilet causes blockages in sewers and possible damage to the environment.  “Disposable” means you should bag it and trash it… don’t flush it!  Most baby wipes and adult wipes are not flushable. Non-flushable wipes do not fall apart in water like toilet paper; they get tangled in the sewage with other wipes and debris, resulting in sewer clogs and expensive problems for us and our residents.
