About this area's water

Did you know
- Gallipolis used to drink the Ohio River. The 1895 waterworks on Mill Creek Road took river water, and only later switched to wells — retiring at 2.2 million gallons a day on three wells when the current plant opened in…
- The city's water was so cheap that Ohio effectively penalized it for it: the 2023 rate ordinance states outright that Gallipolis did not qualify for state loan principal forgiveness because it had let rates stay too…
- Gallipolis is a city that is legally a village — every ordinance and audit is filed under 'Village of the City of Gallipolis' — and it is run by a five-member Commission with an appointed Village Manager.
- The plant softens water in two deep concrete basins with lime, then pushes it out through four pumps sized 1, 1, 2 and 2 million gallons a day from a clearwell holding 0.9 million.
- The link the city labels '2026 Water Quality Report' on its own water treatment page actually downloads its 2025 cash-basis financial statement — and the ohioruralwater.org address its public water system page sends…

History6
- 1895The Gallipolis waterworks was established, with a plant on Mill Creek Road drawing from the Ohio River.

- 1981The James A. Northup Water Treatment Plant started operation in November 1981 at 2020 Chestnut Street, with a gross capacity of 4.0 MGD and five wells provided for use and reserve.
- 1987The wastewater treatment plant received its last major upgrade, a $5.7 million expansion — the last grant/loan financing option the EPA offered the city.
- 2003An odor reduction project at the Water Pollution Control Facility was completed in spring 2003 at a cost of $350,000.
- 2023Ordinance O2023-07 (passed 20 February 2023) raised water rates 13.5% after a four-year freeze, explicitly to reach 1% of median income so the city could qualify for state funding and loan principal…

Supply stress
Not documented as quantity-stressed. Five to six wells feed a plant designed for 4.0 MGD that averages roughly 800,000 gallons a day — about a fifth of capacity — and the wells sit in the Ohio River valley, where recharge is generally ample. What actually strains Gallipolis is money and old pipe rather than hydrology, and the city said…
