Microsoft has thrown its weight behind new legislation designed to stop data centers from shifting water usage costs onto consumers, a move that reflects the tech industry's effort to address growing community unease over the environmental footprint of AI infrastructure.
The Water Cost Accountability Act would require states to prohibit public water systems from recovering expenses tied to connecting data centers from anyone other than the developers or owners of those facilities. The bill is seen as a direct response to local complaints that data centers are driving up utility bills for residents and small businesses.
Fred Humphries, Microsoft's corporate vice president for U.S. government affairs, framed the measure as a step toward responsible expansion. "This legislation represents an important step toward building the infrastructure needed for America's future while strengthening trust with the communities that host it," he said in a statement. "It also reinforces the principle that companies must responsibly show up in communities across the country, engaging as long-term partners and listening to local voices."
The push comes amid a broader backlash against data center development, with residents and local officials raising alarms about water consumption, electricity demand, noise, and environmental degradation. According to the Lawrence Berkeley National Laboratory, data centers consumed roughly 66 billion liters of water in 2023, a figure that is likely to grow as AI workloads expand.
Industry representatives argue that such concerns are exaggerated, noting that newer facilities increasingly use water-efficient cooling technologies. Commerce Secretary Howard Lutnick echoed that sentiment on Wednesday, dismissing water worries as "propaganda by our adversaries to try to slow us down." In a CNBC interview, he claimed, "Data centers don't use water," and pointed to cattle as the real water hog.
However, his comments have drawn sharp criticism, with experts noting that data centers do indeed consume significant water, particularly for cooling. The dispute highlights the tension between the administration's pro-industry stance and the practical concerns of communities.
Republican lawmakers, mindful of the upcoming midterm elections, appear eager to address constituent worries. At a House Energy and Commerce subcommittee hearing Thursday, Chair Gary Palmer (R-Ala.) acknowledged the economic benefits of data centers—investment, job creation, and digital infrastructure—but insisted that "those benefits should not come at the expense of families and small businesses through higher water rates."
The bipartisan nature of the concern is evident, as Democrats have also pushed for greater oversight. The bill's prospects remain uncertain, but Microsoft's endorsement signals that major tech firms are willing to accept some regulatory constraints to maintain social license to operate.
As the debate continues, the issue is likely to feature prominently in political campaigns, with candidates on both sides seeking to position themselves as defenders of ratepayers. For now, the Water Cost Accountability Act offers a concrete test of whether the industry's promises of responsible growth will translate into policy.
