Wastewater
Treatment System
The city's wastewater treatment system is a three-cell complete aerated lagoon, with facilities also provided for chlorination and dechloination of the effluent prior to discharge to the North Platte River. The design capacity of the system could serve a population of approximately 15,000.

The system includes two sewage pumping stations. Two twenty four-inch gravity interceptor lines and one ten-inch force main deliver the collected wastewater to the treatment site. Screw pumps elevate the wastewater into the first of three treatment cells. Flow through the remainder of the treatment facilities is by gravity.

During normal operations, operator attendance at the treatment site is on a part-time basis. The facilities include local and remote alarms and telemetry equipment to provide warning of emergency conditions. The county septic water pumping facility is also located at the wastewater treatment plant site. Available by appointment only.

Protect Yourself and Your Friends and Neighbors! Help Prevent Plugged Sewer Lines!
Your toilet is NOT a garbage can.  Very few items can be flushed down the toilet.  Flushing certain items can result in a back-up of your sewer line into your home and cause problems at the wastewater treatment plant.

What NOT to Flush Down the Toilet:
  • Grease, fats, oils
  • Personal care wipes and/or baby wipes
  • Diapers
  • Cotton swabs
  • Tampons and/or sanitary napkins
  • Condoms
  • Old medicines and/or prescription medications
  • Rags, cloths

While products may be advertised as "flushable", the reality is that such items as baby wipes, makeup remover cloths, and disinfectant wipes do not decompose in the City's sanitary sewer system.  Flushing these materials and others may cause damage to the sewer system as well as cause sewer backups in your home. 

Bottom line: "Flushables" should be disposed of in the garbage.

To protect yourself and your neighbors, only flush biodegradable human solid waste and/or toilet paper.
