OHKIYU VILLAGE MHC is one of 1,221 community water systems in Iowa in the 500 or fewer people size category, formerly serving 55 people from groundwater.

EPA's federal records list this system as inactive in 1975; the record below is historical.

As of August 1, 2026, its federal record holds 12 entries between 1980 and 2007, all of which EPA lists as closed. Nothing has been added since 2007.
