Oakwood City treats its own water from Great Miami Buried Valley Aquifer (wells).

The system's record

Great Miami Buried Valley Aquifer (wells)
Groundwater

The Ohio Department of Health's fluoridation report (CDC My Water's Fluoride) lists Oakwood City as buying its water from Dayton Public Water System; EPA's inventory shows its own sources as primary with Dayton Public Water System as an emergency connection. The two records may reflect a blend or a recent switch.

Wells: EPA lists 8 active wells.

Did you know
  • A city of about 9,600 people runs eight production wells, three water treatment plants, 44 miles of main, 352 hydrants and a 1.5-million-gallon tower entirely on its own.
  • Oakwood's growth was partly a flood-safety pitch: after the 1913 Great Dayton Flood, ads sold Oakwood lots as sitting '275 feet higher than the intersection of Third and Main Streets.'
  • The city softens its raw groundwater from about 27 grains per gallon of hardness down to about 12 - roughly 200 mg/L, still fairly hard tap water by national standards.
  • Oakwood adds no fluoride at all; the roughly 0.24 ppm in the tap is whatever the aquifer happens to supply.
  • Every 100 cubic feet of water billed carries a 10-cent Well Field Protection Fee - a line item on the bill for guarding the ground the city's eight wells draw from.

Treatment & pressure

How it is treated

Groundwater from eight production wells feeding three city-owned water treatment plants - Springhouse (120 Springhouse Rd) and Shafor (210 Shafor Blvd) are the two the CCR names and photographs, and the CCR states three exist. CORRECTION to the draft: three plants, not two. The wells draw from…

EPA record: no health-based violations since 2015.

Supply stress

Ohio EPA rates the aquifer under Oakwood's own wellfield as having MODERATE susceptibility to contamination, citing the sensitivity of the aquifer the wells sit in and several potential contaminant sources inside the protection zone; the city responds with an Ohio EPA-endorsed Source Water Assessment and Protection Program and charges a…

Sewers

Sanitary

The City of Oakwood owns and operates the sanitary collection system but does not treat its own wastewater - about 70% of sanitary sewer operating cost is treatment purchased from Montgomery County and City of Dayton wastewater treatment plants. The whole operation, collection and treatment alike, is funded by user fees rather than…

Storm

A separate storm system, operated by the city's Engineering & Public Works Department: underground storm sewer pipes, roadway gutters, stormwater inlets, and open ditches, creeks and streams, run under a Stormwater Management Plan permitted through Ohio EPA.…
