Water

Lime-softened well water

Fairfield pumps its water from six deep wells in the Great Miami Buried Valley Aquifer and treated more than 2 billion gallons in 2025. At the plant, the water is aerated, softened with lime in clarifiers, adjusted for pH with carbon dioxide, filtered and disinfected. The city's 2025 daily average hardness was 132 mg/L, or 7.7 grains per gallon, with a pH of 8.6.

The city calls its water moderately hard and balanced so it neither coats nor corrodes pipes. It says a home softener is a personal choice, and that water softened to zero hardness is corrosive. Moderately hard water still leaves some scale in a tank over time, so a yearly flush helps. In 2025 the city also drew about 1.5 million gallons from its emergency link with Butler County.

Lead lines

No known lead lines

The city sampled 60 homes for lead in 2025. The 90th percentile was 2.4 ppb, under the 15 ppb action level, though 2 of the 60 samples were over it. The city says there are no known lead service lines or mains in Fairfield, and its service line inventory is posted on the Public Water System page.

Homes

1970s homes, many electric

The median Fairfield home was built in 1978, and only about 2% are older than 1940. About 56% are detached houses, about 26% are in buildings with five or more units, and about 37% of households rent. Electricity heats about 53% of homes and gas about 41%. On an electric tank, running out of hot water fast often points to a failed element or thermostat.

Permits

County permit, Rumpke takes appliances

The city's fee page says plumbing permits and fees are handled by the Butler County General Health District. Its 2026 fee schedule lists a water heater replacement at $40. The health department is at 301 S. Third St. in Hamilton, 513-863-1770.

Rumpke collects Fairfield's trash, and the city lists appliances and bathroom fixtures among items it accepts with regular pickup. If an item is too heavy for one person to lift, call Rumpke at 1-800-582-3107 at least 24 hours ahead.
