What should you flush? Only two things: human waste and toilet paper. Please do not flush...

Wipes, Diapers, Feminine Hygiene Products

Please never flush wipes, diapers or feminine hygiene products, even if they are labeled “flushable.” 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.

Medications & Sharps

 
Please do not flush expired or unused medications down the sink or toilet. Many drugs cannot be completely removed from sewage during wastewater treatment.

Our community offers many safe disposal options for drugs that protect you, your family, and our waterways.

Bring needles, syringes, lancets, Epi-pens, etc. to a collection center in an approved sharps container (sold at pharmacies and available online). Never flush sharps because they can injure wastewater workers. Safe disposal options in our community include:

Note: these options are for home-generated drugs and sharps only. State law requires businesses to use a licensed medical waste hauler.
