WEBSTER CITY WATER SUPPLY is one of 91 community water systems in Iowa in the 3,301 to 10,000 people size category, serving 7,825 people from groundwater.
As of August 1, 2026, its federal record holds 3 entries between 1992 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.
