General Information:
The Iowa Department of Natural Resources (Iowa DNR) administers the Public Drinking Water Program in Iowa under delegation of authority from the United States Environmental Protection Agency.

The Water Supply Engineering (WSE) Section and the Water Supply Operations (WSO) Section are responsible for the programs associated with the public and private water supply systems of Iowa.  Both sections are housed in the Iowa DNR’s Water Quality Bureau.  In addition, the sections are responsible for Iowa’s water allocation and use program; environmental laboratory certification program; certification programs for water operators, wastewater operators, and well drillers; and the technical aspects of the drinking water state revolving loan fund program.  The Iowa DNR’s Field Services & Compliance Bureau has the inspection component of the public water supply program.

A public water supply is defined as a system that provides water for human consumption that has at least 15 service connections or serves at least 25 people at least 60 days during the year.
