On July 1, 2020, USW Utility Group (USWSG) began operating Tenkiller Waterworks, Inc., an investor-owned utility nestled along Tenkiller Ferry Lake in the hilly terrain at the foothills of the Ozark Mountains in Park Hill, Oklahoma. Lake Tenkiller, also known as Oklahoma’s clear water paradise, covers nearly 13,000 acres and has over 130 miles of shoreline.
USWUG provides water and wastewater operations, management and administrative services, maintenance, construction, meter reading, and customer service for the Tenkiller Utility. Tenkiller Waterworks is regulated by the Oklahoma Corporation Commission, which has administrative authority over privately owned utilities in the State of Oklahoma.
Tenkiller Waterworks has a 720,000 GPD conventional water treatment facility that receives its source water from two pumps suspended in Tenkiller Lake. The Wastewater Treatment Plant utilizes coagulation, flocculation, sedimentation, and filtration followed by disinfection in the treatment process. The facility consists of a 36,000-gallon clarifier, an automatic filter, a 45,000-gallon ground storage tank, four high service pumps, and a 2,500-gallon hydropneumatic tank. Chemicals used are alum for coagulation, caustic soda for pH adjustment, and bleach for disinfection. The water system serves 1,340 people in Park Hill. The distribution system is made up of approximately 100,000 feet of water main, 452 connections, 2 fire hydrants, and 200 valves.
Wastewater treatment is provided by a lagoon treatment facility, serving 945 people. USWUG is continuing the process of connecting properties currently on septic and leach fields to the sanitary sewer collection system. The collection system is made up of six lift stations and 43,800 linear feet of force main. The collection system is a low-pressure force main, with solids separation tanks at each property connection.
