Water

Well water, softened at the plant

Harrison pumps from the Great Miami Aquifer through four wells on Thomas Lane and three more across the state line at 153 Harrison-Brookville Road in West Harrison, Indiana. Historically hard, iron-rich water damaged the system, so the city designed a reverse osmosis membrane softening plant, installed in 2022. It treats about 1.5 million gallons a day and is meant to cut both hardness and pipe corrosion.

The city's water page gives the softened target as 40 mg/L and also as 8 grains per gallon. Those two figures don't match (40 mg/L is about 2.3 grains), so test your tap before you set or bypass a home softener. The city says iron is non-detectable, and if water runs brown, run only the bathtub cold tap until it clears, with any softener on bypass.

Lead lines

Inventory online

The 2025 report says none of 30 lead samples was over the action level, with a 90th percentile of 0.7 ppb. The city's service line inventory, listing the material recorded for each address, is linked from its Utilities page.

Homes

Newer homes, mostly electric

The median Harrison home was built in 1992, and about 42% date from 2000 or later. About 65% of homes heat with electricity and only 34% with gas. If your water heater is electric and runs lukewarm or goes cold, a failed element or thermostat is a common cause. About 25% of households rent, and about 19% of homes are in buildings with five or more units.

Permits

County permits, pans and Saturday checks

Harrison sends plumbing to the Hamilton County Plumbing Division, 513-326-4541. Hamilton County Public Health requires a permit and inspection for every new or replacement water heater. If a store or contractor installs yours, make sure they pull the permit. A homeowner doing the job in their own single-family home may qualify for a homeowner permit.

The county's fact sheet says a drain pan is needed about 9 times out of 10, including in slab homes, attics, finished basements and anywhere a leak could damage floors or walls. It also schedules water heater inspections on the second Saturday of each month for people who can't do a weekday.
