Indian Hill Water Works customers should not experience a change in service reliability because of Terrace Park’s planned departure, the Village of Indian Hill says in its public FAQ. Officials pledged continued maintenance, infrastructure investment and compliance with drinking-water requirements.
The assurance concerns a transition still being arranged, rather than an already completed switch to Greater Cincinnati Water Works.
Notice gives a year under the existing contract
Indian Hill’s formal notice dated Oct. 29, 2026 says the current water-service agreement will terminate one year from the notice date—Oct. 29, 2027. City Manager Dina Minneci wrote that Indian Hill would provide uninterrupted service under the agreement during that year.
The letter calls for a separate transition-services agreement covering timing, financial responsibilities and infrastructure. The contract’s termination date does not itself establish the date Terrace Park will begin receiving GCWW water.
A smaller PFAS treatment project
Indian Hill says it submitted a revised General Plan to the EPA on Oct. 29 to seek approval for a smaller, less costly PFAS treatment facility, according to its PFAS project update. The plan reflects the lower demand expected after Terrace Park leaves.
The village is planning around an April 2029 compliance deadline. The U.S. EPA has proposed allowing systems to request two additional years, to 2031, for PFOA and PFOS compliance; that proposal is separate from an approved extension for Indian Hill.
Costs and the remaining system
The village’s capital-cost FAQ describes reducing the planned PFAS facility’s size by approximately 25% and rehabilitating the existing Miami Road water tower instead of replacing it. Those are planned savings and project decisions, rather than completed work.
Its rate projections say Terrace Park’s departure should not cause significant increases for remaining customers. Future rates will still depend on operating expenses, infrastructure and regulatory needs.
