Hamilton Public Water System as a whole draws on: Great Miami Buried Valley Aquifer (wells).

Monroe City buys its water from Butler Co. Water District 2, which buys from Hamilton Public Water System. Hamilton Public Water System treats groundwater from Great Miami Buried Valley Aquifer (wells).

Also connected to Cincinnati Public Water System (Ohio River (Miller Plant, ~88%) plus Great Miami Buried Valley Aquifer wells (~12%)), used as a secondary or emergency supply.

Monroe City is owned by a local government, with 4,536 service connections serving 15,600 people. Office: 513-500-9181 (SDWIS).

EPA modeled the service boundary of Monroe City (random forest) rather than drawing it from the utility's map, so its edges are approximate.

Bills, 2023: a household using 5,000 gallons a month paid about $554 a year for water ($46 a month; $330 at 2,500 gallons, $823 at 8,000) (Ohio EPA rate survey, inside-city rates).

Wells: EPA lists 21 active wells. ODNR well logs locate 8 public-supply wells inside Hamilton Public Water System's wellhead protection zone, 60 to 208 ft deep, in sand & gravel and sand. Zoom in to see them as dots.

About this area's water

  • Monroe's tap water is a blend of two very different sources that meet before they reach the city: Ohio River surface water from Greater Cincinnati Water Works and Great Miami Buried Valley Aquifer groundwater from…
  • Monroe holds emergency interconnections with the City of Middletown and with Warren County Water, and used no water from either during 2025.
  • The Great Miami Buried Valley Aquifer is watched over by the Hamilton to New Baltimore Groundwater Consortium, which the county utility credits with an award-winning groundwater protection program.
  • Greater Cincinnati Water Works' granular activated carbon treatment on Ohio River water lets it use substantially less chlorine than a conventional plant would need.
  • A 29% wholesale increase from Butler County, which the city absorbed for a year before passing it on, pushed Monroe's inside-city water rate from $8.23 to $10.61 per 1,000 gallons on January 1, 2026.

Treatment & pressure

How it is treated

Monroe treats no water of its own. It buys finished water from Butler County Water & Sewer - Butler County Water District 2 - and distributes it. BCWS in turn buys surface water from the City of Cincinnati (Greater Cincinnati Water Works), drawn from the Ohio River and treated with granular…

Both of Monroe's upstream sources are rated highly susceptible to contamination by Ohio EPA, for opposite reasons.

Mostly estimated. Only 1% of these days come from a gauge standing inside 45050 (Monroe) - the rest are worked out from the nearest gauges around it, so read them as close estimates rather than readings.

48,045 days of records, 1893-01-01 to 2026-10-29. 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 2026-10-31): correlation 0.9515, median absolute difference 0.217 in a month. Built 2026-10-31 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.
