Piqua City is owned by a local government, with 8,824 service connections serving 20,354 people; it has substantially implemented source water protection under Ohio's program. Office: 937-778-2090 (SDWIS).

EPA modeled the service boundary of Piqua 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 $838 a year for water ($70 a month; $526 at 2,500 gallons, $1,212 at 8,000) (Ohio EPA rate survey, inside-city rates).

Ohio EPA loans since 2016 for projects inside this ZIP: $56.6 million across 3 projects, $60,000 of it forgiven (wastewater $53.2M, drinking water $3.4M); largest: Wastewater Plant Expansion NRD (Piqua, 2017, $53.2M); New Central Water Tower (Piqua, 2016, $3.4M); Asset Management Plan (Piqua, 2019, $10K).

  • Piqua's drinking water partly comes from a chain of Ohio canal-era lakes and canals still called the 'hydraulic system' - Swift Run Lake, Echo Lake and Franz Pond - blended with water from a converted gravel quarry and…
  • The Ernst gravel pit is really two adjoining lakes: the 4.5-acre one Piqua owns, and a 32-acre neighbor in private residential ownership. It is the city's preferred source because its organic carbon is lowest, but it…
  • Piqua sits in an area with a federally designated sole source aquifer and still cannot drink from it - the sand-and-gravel groundwater yield is too limited, so the city takes all of its water from the surface.
  • A single algae sample collected July 27, 2010 confirmed cyanobacteria in the reservoir source; algae has been a tracked concern in the watershed ever since, and the city's lab now sells harmful-algal-bloom microcystin…
  • Spring atrazine in the Swift Run Lake reservoir once peaked at 85 parts per billion - about 28 times the drinking water MCL - before treatment; the 2025 finished water measured 0.08 ppb.

  • 2005-2010Source monitoring found spring atrazine peaks of 85 ug/L in the Swift Run Lake reservoir and 33 ug/L in the Great Miami River, and TOC as high as 9.2 mg/L in the reservoir - both driven by row-crop…
  • 2010A single algae sample taken July 27, 2010 confirmed cyanobacteria (blue-green algae) in the reservoir source.
  • 2011SWAP update (March 2011) found finished water compliant with all U.S. EPA and Ohio EPA rules but flagged the Stage 2 D/DBP rule for TTHMs as an upcoming challenge; documented a 7 MGD plant averaging…

Supply stress

Piqua relies entirely on surface water. Part of its watershed sits over a federally/Ohio EPA-designated sole source aquifer, but the sand-and-gravel aquifer yields too little for city demand, so all supply comes from the hydraulic system, the Ernst gravel pit (limited to under 30% of needed volume) and the Great Miami River. Ohio EPA's…

48,508 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.
