40. Community Need Dayton Water, a true regional asset, serves nearly 400,000 residents of the City of Dayton, and other nearby neighbors, including Kettering, Brookville, Clayton, Trotwood, Riverside, Moraine, Harrison Township, Centerville, Washington Township, parts of Greene and Butler Counties, and some base housing for WPAFB. Also, Dayton maintains connections for emergencies to Vandalia and Oakwood. Dayton Water serves major hospitals, schools, and universities, numerous healthcare services, and thousands of businesses. Dayton Water has been diligent over the years in maintaining its facilities to keep the water rates as low as possible since some of the ratepayers in Dayton and other neighbors served by Dayton Water are economically disadvantaged. Dayton Water is among the lowest-cost water systems in the region.
Dayton Water maintains two, redundant 96MGD water treatment plants: the Maimi Water Treatment Plant and the Ottawa Water Treatment Plant, each able to maintain the demand of the entire system. Still, the whole system is most efficient when both plants work together and complement each other. In addition to redundancy and efficiency, the Maimi Water Treatment Plant is expected to increase production as the regulations for PFAS levels tighten. To accommodate the expected increase in water production, the City has begun to invest in more wells to bring more water to the Maimi Treatment Plant as the levels of PFAS are under the detection limit at the Miami Well Field. Increasing production is part of the overall PFAS treatment strategy for Dayton Water. The overall strategy takes into consideration the cost of treatment to decrease the burden of PFAS treatment for the ratepayers.
The Miami Water Treatment Plant process includes four contact clarifier basins, which need updates as they are approaching the end of useful life. The plan is to rehabilitate two basins at a time, starting with the two in most need of repair. Rehabilitating two at a time will allow Dayton Water to maintain water treatment at the Maimi Water Treatment Plant throughout the course of the project. The project will replace the contact clarifier parts, repair concrete as needed, and reinstall protective coatings where necessary.
