Greene County - Fairborn

• The Mad River Well Field is only 42 acres, but its wells each produce anywhere from 800 to 2,600 gallons per minute.
• Raw water travels about 9,000 feet from the well field to the treatment plant through a single 24-inch main.
• Fairborn's lead service line inventory found no lead lines, no galvanized lines requiring replacement, and no unknown-material service lines anywhere in the system.
• The plant produces more than a billion gallons of drinking water a year and holds an unconditioned Ohio EPA operating license.

• 1950The villages of Fairfield and Osborn merged to form the City of Fairborn, whose name blends the two.
• 1974-1975The Mad River Well Field was constructed in 1974 and the City of Fairborn Water Treatment Plant began operating in 1975.
• 1990Four new filters were added to the plant, raising rated capacity to 5.0 MGD; the well field was expanded again in 1994.
• 2008Ohio EPA approved a capacity increase to 6.5 MGD and the Mad River Well Field was expanded.
• 2021The most recent Mad River Well Field expansion was completed.

How it is treated

Wells at the Mad River Well Field over the Great Miami buried valley aquifer; water is oxidized with potassium permanganate and/or chlorine, filtered to remove iron and manganese, then chlorinated and fluoridated before storage in two 1.5-million-gallon clear wells.

Water pressure

Not published; Fairborn's Water & Sewer Division states only that it aims to deliver drinking water 'at adequate pressures.' No psi or pressure-zone figures found.

Not substantiated. Fairborn's utility billing, utilities-documents and finance pages carry no rate schedule and refer callers to (937) 754-3006.

Ohio EPA's 2024 source water assessment rates the aquifer highly susceptible: no protective clay layer, less than 20 feet deep, and significant potential contaminant sources in the protection area. It found no evidence the groundwater has been impacted by significant chemical contamination from human activity.

Sanitary

City-run Water Reclamation Center at 6920 Upper Valley Road, Huber Heights: rated up to 6 MGD, currently averaging about 4 MGD, discharging to the Mad River. Wastewater flows by gravity to collection-system low points where six pump stations lift it. SCADA-monitored 24/7.

Storm

The Water & Sewer Division maintains a separate storm water collection system (pipe and inlet maintenance); no stormwater utility fee schedule or flooding history was published in sources reviewed.

Compiled from the utility's own reports and public records, then independently re-checked against primary sources.
