The numbers come first. A single AI data center can consume millions of gallons of water per day. U.S. data center demand is projected to double between 2025 and 2027. Ecolab CEO Christophe Beck looked at those two facts and wrote a $7 billion check.
Beck, who leads the $16 billion-a-year water-and-hygiene company ranked No. 280 on the Fortune 500, told Fortune that Ecolab has deployed $7 billion over the last six months to expand its position in high-tech water management. The centerpiece is a $4.75 billion acquisition of CoolIT, a Calgary-based liquid-cooling company.
What CoolIT actually does matters. The firm uses closed-loop technology that captures heat from high-density chips without spraying or evaporating water into the air — a critical distinction when communities are already pushing back against the volumes data centers pull from local water supplies. 'We can generate power, we can't generate water,' Beck said. 'Now we have a solution that's really allowing us to make data centers water-neutral.'
For Ecolab, the deal is not a pivot — it is an acceleration. The company already provides ultra-pure water for chip fabrication, cooling water for power generation, and water management services across 3 million customers in 172 countries. CoolIT adds what Beck describes as a mission-critical layer: direct involvement in how chips are cooled, how energy flows through a facility, and how the systems are operated end to end.
The business case is straightforward. CoolIT plugs into what Ecolab calls a fast-growing, high-margin segment. Beck framed the strategic logic without ambiguity: 'More money, more growth, better impact and unleashing the best industries in the world.' The acquisition also advances the company's 2030 targets, set in 2019, which include cutting carbon emissions in half, helping customers conserve 300 billion gallons of water annually, and protecting 2 billion people from foodborne illnesses.
The broader market backdrop reinforces the timing. AWS posted $42.2 billion in second-quarter revenue, up 37% year over year — its fastest growth in 18 quarters. Amazon CEO Andy Jassy noted that AWS, at a $169 billion annualized run rate, would rank 24th on the Fortune 500 as a standalone company. Hyperscale infrastructure is not slowing down, and every new server rack is a new water-management problem.

The CEO Times read: This is free enterprise solving a resource problem that regulators have spent years failing to address. Ecolab did not wait for a federal mandate on data center water consumption — it identified a constraint, priced the risk, and deployed capital. That is how competitive markets are supposed to work.
The deal also illustrates a durable principle: established companies with deep process expertise and customer relationships hold structural advantages in technology transitions. Ecolab has 103 years of operational credibility in water treatment. CoolIT has the engineering for the next generation of chip cooling. Together they give hyperscalers a path to build without draining municipal water systems — and give Ecolab shareholders a stake in every new data center that comes online. Capital rewards clear rules, and the rule here is simple: AI scales only as fast as its infrastructure constraints allow.
