Warren County as a whole draws on: Wells in the Little Miami and Great Miami river valley aquifers. Of its plants, only the one above serves this ZIP.

Warren County is owned by a local government, with 30,361 service connections serving 81,975 people (SDWIS).

Boundary caution: EPA's service-area polygon for Warren County, from the utility's own map, holds only 47% of the 81,975 people it reports serving, so much of its territory shows on this map as private wells.

Bills, 2023: a household using 5,000 gallons a month paid about $282 a year for water ($24 a month; $169 at 2,500 gallons, $451 at 8,000) and about $280 a year for sewer (Ohio EPA rate survey, inside-city rates).

Ohio EPA loans since 2016 for projects inside this ZIP: $707,000 across 2 projects, $705,000 of it forgiven (drinking water $707K); largest: Ion Exchange Treatment at Richard A Rennker WTP (Warren County, 2025, $691K); Granular Activated Carbon Upgrades (Warren County, 2023, $16K).

Wells: EPA lists 24 active wells. ODNR well logs locate 9 public-supply wells inside Warren County's wellhead protection zone, 40 to 91 ft deep, in sand & gravel and sand & boulders. Zoom in to see them as dots.

Did you know
  • Warren County reports no lead, no galvanized-requiring-replacement, and no unknown-material service lines anywhere in its distribution system.
  • The system is a patchwork of five sub-systems: Franklin-Clearcreek and Richard Renneker on county wells, Socialville on Cincinnati water, and Pennyroyal and Sharts Road on Springboro water.
  • A November 2024 lab mix-up - nitrite tested instead of nitrate - drew an Ohio EPA monitoring violation even though the retest came back below the nitrate limit.
  • The 24 county wells pump more than 2 billion gallons a year, and the finished water averages 140 mg/L of hardness, about 8 grains.
History5
  • 1960sThe Warren County Water & Sewer Department began operating and says it has never permitted lead pipe in its mains or on customer service laterals.
  • 2022Softening started up at both plants after a corrosion control study done with Ohio EPA, and nanofiltration membrane treatment was added.
  • January 2023Nanofiltration membrane construction was completed, cutting hardness and improving removal of PFAS, pesticides and herbicides.
  • July 2024Ohio EPA approved merging the Franklin-Clearcreek and Richard Renneker systems into the new Warren County Public Water System.
  • April 2025The county began building ion exchange PFAS treatment at the Renneker plant, scheduled to finish that November.
Treatment & pressure

How it is treated

24 wells in 5 wellfields feed two county plants: Franklin Area (7 wells) and Renneker (4 wellfields). Softening, nanofiltration membranes, pH control with sodium hydroxide and orthophosphate, then fluoride and chlorine; Renneker adds ion exchange for PFAS.

Water pressure

The county uses elevated storage such as the 20 Mile elevated tower rather than publishing a system average.

What it costs

$5.70 per 1,000 gallons

2026 water: $34.20 bimonthly minimum covers 0-6,000 gal, then $5.70 per 1,000 gal, plus a $5.00 bimonthly repair/replacement charge. Sewer billed separately.

EPA compliance record

Lead at the tap: 90th-percentile result 1.3 ppb in 2026 (action level 15 ppb).

EPA record: no health-based violations since 2015.

2 violations of any kind logged since 2020: 2 for a report, record or notice that was missing, late or incomplete (the yearly water quality report, a public notice, lead line records).

Projects & plans4

Recent and current work

  • Nanofiltration membrane treatment at both plants · 2023 · completed
    Added in 2022 and completed January 2023 at Renneker and Franklin Area; cuts hardness and removes PFAS, pesticides and herbicides.
  • Renneker Water Treatment Plant ion exchange PFAS system · 2025 · completed
    Anion exchange added to the existing nanofiltration building; AECOM engineer, Shook Construction builder.
  • Franklin-Clearcreek / Richard Renneker system merger · 2024 · completed
    Ohio EPA approved consolidation into a single Warren County Public Water System in July 2024.

Planned or needed

  • Future capital program
Supply stress

Ohio EPA classes the Great and Little Miami buried valley aquifers highly susceptible, given contaminant sources in the protection areas. Low PFAS at the Renneker wellfields drove nanofiltration then ion exchange. 15% of customers drink Springboro water, whose aquifer sits under 5 ft of cover.

Sewers

Sanitary

The Warren County Water & Sewer Department also runs county sanitary sewer. 2026 sewer rates are a $34.32 bimonthly minimum for 0-6,000 gal then $5.72 per 1,000 gal, with a separate Carlisle-area sewer-only rate.

Mostly estimated. Only 3% of these days come from a gauge standing inside 45039 (Hamilton Township and Maineville) - the rest are worked out from the nearest gauges around it, so read them as close estimates rather than readings.

47,950 days of records, 1893-01-01 to 2026-10-30. Source: NOAA NCEI GHCN-Daily, 3,240 gauges in and around Ohio. A day is "gauged" when a gauge standing inside the boundary reported it, and the value is the mean of those gauges. Otherwise it is interpolated by inverse distance from every gauge reporting within 50 miles. Nothing is carried forward, back-filled or smoothed. Against NOAA nClimDiv county monthly precipitation over 136,848 complete county-months (checked 2026-11-01): correlation 0.9515, median absolute difference 0.217 in a month. Built 2026-11-01 from the Cracked Buckeye precipitation archive. Snow is the softer number — snowfall is measured by hand with a ruler, no agency publishes a gridded county snowfall series, and blowing snow defeats every observer.
