What To Flush

no-links-infographic-3-pOnly Flush The 3 P's

Here at the City of Superior Wastewater Treatment Plant, about 4 million gallons per day of wastewater flows into the treatment facility. Wastewater, also known as influent, arrives from homes, schools, apartments, businesses, and churches in Superior.  

People tend to flush medications, sanitary products, deceased pet fish, wet wipes, and many other items that should not be flushed! Toilet paper is designed to break down in a matter of seconds, whereas wipes are designed to withstand moisture and remain intact. Wipes may flush down but tend to cause clogs downstream in the sewer system leading to costly problems in our homes, wastewater treatment network, and the environment. 

The toilet is only intended to flush the 3 P’s—pee, poop, and (toilet) paper. Human waste and toilet paper should be the only thing going down the toilet!  

Old or Expired Medications

Unused or expired medications should be taken to pharmaceutical disposal sites and never disposed of down the drain or toilet

Pharmaceuticals are not removed by current wastewater treatment practices and can pass through to our waters, negatively impacting aquatic species, and contaminating our food and water supplies. 

Where do I bring old or expired medications? Or unwanted e-cigarettes or vape products?

Medications & vape products are accepted at the Superior Police Department (4808 Hammond Avenue) front desk located on the first floor of the Douglas County Court House. **Old or expired meds are also accepted at pharmacies in Superior, WI (dropbox at each pharmacy)

  • Old or expired meds: Accepted materials include pills, liquids, salves, powders, inhalers, and pet meds—no sharps or biological material. To prepare your prescription meds you may use a marker to cover your name but leave the name of the drug visible.
  • Vape products: e-cigarettes, vapes

Vapes contain lithium-ion batteries. These batteries can cause dangerous fires if they are crushed or overheated. Flushing or throwing away these items could potentially cause harm to the maintenance crews and equipment.
