The Water Treatment Plant is located off Arnold Road in Washington County. The water source for the system is the Nolichucky River and the plant uses a charcoal filtration process, and a MIOX, mixed oxidant, disinfection process that is much safer than chlorine gas, and more effective as a disinfecting agent. The MIOX process also eliminates the taste and odor problem associated with chlorine gas.
The Water Treatment staff not only operates and maintains the water treatment plant and grounds, but is also responsible for maintaining the pump stations in the water system as well as all of the water storage reservoirs. The system has over 5.4 million gallons of storage. Treatment staff also collect some of the test samples in the system required by the Tennessee Department of Environment and Conservation
