The Wastewater Collection and Treatment system of the City of Pratt is a full-service utility system providing the collection and treatment of residential, commercial and industrial wastewater throughout the city.

There are approximately 38 miles of sewer main pipe and several hundred manholes to maintain in the City of Pratt. All sewage in the City is gravity fed to the plant without the use of any lift stations. The Pratt Airport has its own separate collection system with a lagoon treatment system that is also maintained by the City. The Wastewater Department, with the use of a high pressure water and vacuum truck, cleans the lines annually in the City.

The Wastewater plant was built in 1960. In 1989, a 1.3 million dollar rehabilitation was completed to meet the requirements of the new state issued permit. In 1999 more stringent E.P.A. and K.D.H.E. parameters for ammonia and nitrates were added to plant permit requirements. The Wastewater plant was upgraded to an (SBR) Sequencing Batch Reactor plant. Preliminary and primary treatment remained the same but secondary treatment was improved so ammonia and nitrates could be targeted with the treatment process. Chlorine gas was discontinued and a U.V. disinfection basin was added for bacteria treatment at the end of the plant process. The plant contributes approximately 750,000 gal / day of effluent to the Ninnescah River. Downstream is a County lake and State Fish Hatchery so it is important for the plant to meet the new criteria.
