Did you know
  • Galion's water plant is rated for 4 million gallons a day but treats only about 1.3 million — roughly a third of capacity most days.
  • The city's three reservoirs hold about 527 million gallons of raw water for a system serving roughly 10,450 people, but the source reservoir itself is tiny: Ohio EPA measured Amann Reservoir at just 24 acres and 13.1…
  • Galion's water is not really from Galion — Amann Reservoir sits south of town in Morrow County, and the water is pumped from there into two more reservoirs before it ever reaches the plant.
  • Water rates in Galion are set administratively by the Safety-Service Director; only sewer and electric rates go through a City Council ordinance.
  • If Galion ever runs short, it can open a connection to the City of Crestline — an option it did not use in either 2024 or 2025.

Treatment & pressure

How it is treated

Surface water only, no wells. Raw water is the Rocky Fork of the Olentangy River, impounded in Amann Reservoir south of Galion in Morrow County, then pumped into the Amick and Powers upground reservoirs, which feed the treatment plant at 625 W Railroad St. Conventional treatment — clarification and…

What it costs

$13.81 per 1,000 gallons

Typical household bill about $80 a month for water.

From the City of Galion Consolidated Fee Schedule (updated March 1, 2023), the most recent schedule published on the city site; it shows identical in-town water rates in the Jan…

Supply stress

The vulnerability here is water quality in a very small, very shallow reservoir, not scarcity. Ohio EPA's inland lake report on Amann Reservoir (2016-17 sampling, published July 2019) found a lake of only 24 acres with a maximum depth of 4.0 meters (13.1 feet), 262 acre-feet behind a 550-foot dam plus another 220 acre-feet behind an…

Sewers

Sanitary

The City of Galion operates its own sanitary sewer system and wastewater treatment plant, billed separately from water on the customer's utility bill. Sewer is charged on metered water usage per 100 cubic feet using the same ladder as water: in-town $7.51/month minimum plus $10.33 per 100 cu ft for the first block, declining to $4.13…

Storm

Galion charges a stormwater fee of $6.00 per month as a flat rate to all residential customers; undeveloped property is not charged. Non-single-family and commercial property is billed by equivalent residential units, where one ERU is 2,204 square feet of…
