Smart Water Speeds Up as Data Centers Rethink Cooling

A Badger Meter deal and Microsoft’s cooling shift show how utilities and tech firms are rethinking water use as digital demand grows

21 Jan 2026

A quiet shift is gaining speed in the US water sector, shaped by sharper data tools and a digital economy learning to sip rather than gulp.

One clear signal came January 31, 2025. Badger Meter agreed to buy SmartCover for $185 million, a move that pushes the company beyond meters and deeper into real-time monitoring of sewers and collection systems. It reflects a broader rethink underway at utilities nationwide.

The old model relied on periodic checks and fixing problems after they surfaced. The new approach favors constant data, early warnings, and faster action. The goal is to spot trouble before it spills into streets or homes.

Badger Meter says the SmartCover deal strengthens its BlueEdge digital platform, responding to growing demand for tools that boost efficiency and support proactive management. For utilities, the logic is straightforward. Continuous monitoring cuts surprises, reduces emergency repairs, and helps stretch limited staff and budgets.

Pressure is also coming from outside the utility world. Data centers are spreading as cloud computing and AI grow, and their water use has drawn scrutiny. In West Des Moines, Microsoft says new data center buildings will use closed-loop cooling systems that nearly eliminate fresh water for cooling. Instead of pulling in constant new supplies, the systems recycle water internally and avoid evaporation.

For water planners, that difference matters. Data centers can become major customers, especially during hot months when systems are already strained. Designs like Microsoft’s can save about 125 million liters of water per facility each year, easing concerns about supporting digital growth without draining local supplies.

The shift brings trade-offs. Using less water often means using more electricity, and reliable power is just as critical for public services as it is for servers. Utilities and local governments will need better planning tools and earlier talks with developers, long before construction begins.

Taken together, these moves point to a more modern water playbook. Smart water is no longer a side project. It is becoming central to how communities manage growth, attract investment, and build resilience for what comes next.
