This bill establishes new reporting requirements for large water use facilities in Iowa, specifically those that utilize 25,000 gallons or more of water per day. It defines a "large water use facility" as one primarily engaged in data processing services, ethyl alcohol manufacturing, or cryptocurrency mining. The bill mandates that these facilities submit an annual report to the Department of Natural Resources by March 31 each year, detailing their water usage from the previous year.

The legislation aims to enhance oversight of water consumption by large facilities, particularly in light of the growing prevalence of cryptocurrency mining, which can be water-intensive. By requiring detailed reporting, the bill seeks to ensure that water resources are managed sustainably and that the impact of large water users on local water supplies is monitored effectively.
