UNI-CITY is one of 1,277 community water systems in Oklahoma in the 500 or fewer people size category, formerly serving 348 people from surface water.

EPA's federal records list this system as inactive in 2019; the record below is historical.

As of August 1, 2026, its federal record holds 7 entries between 2003 and 2017, all of which EPA lists as closed. Nothing has been added since 2017.

Of the 7, 4 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves the Total Coliform Rules and the Consumer Confidence Rule.
