MANNFORD is one of 106 community water systems in Oklahoma in the 3,301 to 10,000 people size category, serving 3,935 people from surface water.

As of August 1, 2026, its federal record holds 25 entries between 1996 and 2010, all of which EPA lists as closed. Nothing has been added since 2010.

The record involves the Stage 1 Disinfectants and Disinfection Byproducts Rule, the Surface Water Treatment Rules, and the Lead and Copper Rule.
