The City of Lake Ozark shares a wastewater treatment plant (WWTP) with the City of Osage Beach. The Lake Ozark/Osage Beach Wastewater Treatment Plant is located on the Osage River in Miller County. The WWTP is operated by a private company, Alliance Water Resources, and both cities share in the cost of the facility proportionately based on flow.
The Lake Ozark/Osage Beach Joint Sewer Board administers the structure, processes, equipment, and arrangements necessary to treat and discharge wastewater at the WWTP.
