Water Use Disclosures

AB 93 requires that data centers disclose their water use. As filed, the bill would have required public disclosure of the water use. After amendment, the water use is disclosed, but directly to regulators. Thus, the public disclosure is a bit murkier. The bill is awaiting the Governor’s approval.

This isn’t a new trend but it’s gaining momentum. In 2024, Michigan enacted HB4906 requiring public disclosure of water use by data centers.
