What Not to Flush
What should you flush? Only human waste & toilet paper.
Never Flush Medications
Please do not dispose of expired or unused medications in the sink or toilet. Wastewater treatment does not completely remove drugs and traces will end up in Reclaimed system as well as the Rio de Flag. Our community offers safe disposal options for drugs that protect you, your family, and our waterways.
Remove personal information from container labels or combine pills and capsules and seal in a plastic bag. Leave liquids and creams in their original containers (black out personal information) and seal in a plastic bag.

Never Flush Diapers, or Feminine Hygiene Products
These products do not disintegrate in water as quickly as toilet paper and often cause clogs in public sewer mains. Put these items in the trash, not the toilet.
See the results when Consumer Reports and the Water Environment Federation tested so-called flushable products. If wipes can clog large sewer mains, they can definitely clog your home's sewer lateral, requiring you to pay a plumber to clear the blockage.
