Indian Hill projects that Terrace Park’s planned departure from its water system will not cause significant rate increases for remaining customers, according to the village’s rate FAQ.

That forecast accounts for losing customer revenue while reducing future capital spending. It is not a pledge to freeze rates: the village says future adjustments will still reflect operating costs, regulatory obligations and infrastructure needs.

The 2026 comparison has limits

Indian Hill’s water rate increased 5.00% in 2026, compared with GCWW’s 5.55% base-rate increase, the village says. Its comparison excludes GCWW surcharges for customers outside Cincinnati’s corporate limits. Those percentages therefore do not establish which utility would produce a lower total bill for every household.

Smaller projects underpin the forecast

The village’s capital-plan explanation says reduced demand would let it shrink the planned PFAS treatment facility by approximately 25% and rehabilitate the existing 500,000-gallon Miami Road water tower rather than replace it.

Officials project about $10 million in long-term capital savings from the tower alternative. The described work includes a new liner, roof replacement and exterior repairs. These figures are village projections, not savings already realized.

A separate project update says Indian Hill submitted a revised General Plan to the EPA on Oct. 29, seeking approval for the smaller PFAS facility. The village continues planning around an April 2029 compliance deadline.

Why Terrace Park sought a change

Terrace Park’s June 23 Public Works Committee minutes record Mayor Tepe’s wish for the village to leave the water-line business. The minutes say GCWW offered to assume its infrastructure as-is, while Indian Hill had required upgrades first. They describe Terrace Park’s lines as more than 60 years old.

Indian Hill’s Oct. 29 formal notice sets termination of the existing service contract one year later, on Oct. 29, 2027. The letter promises uninterrupted service under that contract during the notice year and calls for a transition-services agreement addressing timing, costs and infrastructure. That contract date is separate from the eventual start of GCWW service.
