The Data Center Water Problem Is Soluble
ITIF has published a policy report arguing that data center water use can be managed through state-led regulation, standardized disclosure, watershed-based review, and targeted federal support.
- The report says states should require facility-level water disclosures, use watershed-specific performance standards, and establish joint water-energy review for large data center loads.
- It also recommends federal action on standardized metrics, procurement, and R&D rather than a national water mandate; examples cited include Nvidia Rubin liquid cooling and Microsoft zero-water cooling designs.

900-acre data center could be built in Salix, Iowa
MidAmerican sent a letter to the Salix City Council on June 8 stating it is evaluating a 900-acre parcel for possible development as a data center and that its affiliate has acquired options on the property.
- Main announcement: MidAmerican (MidAmerican Energy) said the site bounded by Old Highway 75, 260th Street, and Charles Avenue is “being evaluated for possible development as a data center site”; its affiliate Midwest Capital Group, Inc. has acquired options on the property to transfer to a future customer. No end-user customer has been chosen; any customer would be required to pay the full cost of the infrastructure needed to serve its load (including generation, transmission, and substation investment) and would pay approved electric rates for a customer of this size.
- Background and procedural details: The 900-acre parcel was annexed by the Salix City Council in April; Salix officials said no rezoning application had been submitted as of June 10. Local opposition includes a Change.org petition with more than 540 signatures, and Woodbury County passed a data center moratorium on June 23 (which blocks approvals on unincorporated county land but does not directly block the annexed city land).
