The Wastewater Treatment Plant is continually undergoing procedural changes and minor upgrades to comply with newly issued Federal and State regulations. Staff continually monitor ways to improve the treatment process to stay in line with existing regulations and prepare for pending legislation. Since the Walnut River was declared an outstanding national resource water in the late 1990's, the treated water discharged into the river must meet the strict permit requirements prescribed by the Environmental Protection Agency and the Kansas Department of Health and Environment. Currently the plant treats 600,000,000 gallons annually. Much of the effluent is pumped to Quail Ridge Golf Course for irrigating purposes. The treatment plant has pumped as much as 125,000,000 gallons a year to the Golf Course. Plant personnel participate in ongoing training programs and have received awards for statewide recognition of excellence in performance standards, safety and biosolids treatment.
