Data Center Water & Wastewater Treatment Equipment Market worth $5.90 billion by 2031 - Exclusive Report by MarketsandMarkets™

MarketsandMarkets projects the data center water & wastewater treatment equipment market to grow from $3.30B in 2026 to $5.90B by 2031, implying a 12.3% CAGR (2026–2031). Growth is supported by hyperscale/colocation expansion and AI-driven high-density computing, alongside stricter water-use and discharge regulations. Europe is flagged as the fastest-growing region (16.3% CAGR) and membrane & high-purity water systems as the fastest-growing equipment type segment (17.0% CAGR), though high capex and integration costs remain headwinds.

Analysis

This is a better read-through on recurring aftermarket economics than on upfront equipment demand. The economic winner is whoever can monetize treatment chemicals, membranes, monitoring, and service contracts after the rack is installed; that favors ECL most cleanly, with XYL second, while VEOEY is more exposed to project execution and Europe-specific permitting friction. The market may underappreciate that data-center water spend can become sticky O&M revenue, but it is still a small slice of these companies’ enterprise value unless hyperscaler orders start appearing in backlog commentary.

The contrarian risk is that the TAM headline overstates capture rates. Hyperscalers are incentivized to reduce water intensity per MW over time, which caps unit growth and can shift spend toward design changes that lower the need for third-party treatment. In that world, the right read-through is margin mix, not revenue step-change; the winners are the vendors with installed-base pull-through and software-enabled monitoring, not the firms selling one-off hardware into a crowded spec cycle.

Time horizon matters: there is no immediate catalyst from this kind of market report, so the trade only works if it shows up in 1-3 month earnings calls, backlog, or guide raises. If ECL/XYL do not cite hyperscale wins over the next two quarters, the thesis should be treated as thematic noise rather than fundamental inflection. Europe’s stricter rules can also create delay risk, making VEOEY’s upside more uneven than the headline growth rate suggests.

Key Decisions for Investors

• Watchlist, not chase: wait for next ECL and XYL earnings calls for explicit hyperscale/data-center backlog commentary before adding exposure; if confirmed, the setup is a 6-12 month multiple-supporting growth kicker rather than a near-term re-rate.
• Relative value: long XYL / short VEOEY into the next 1-2 quarters if you want to express the theme, because XYL is better levered to installed-base treatment and monitoring, while VEOEY is more exposed to project timing and European regulatory delays.
• Preferred long: accumulate ECL on weakness only if management confirms data-center pull-through in chemicals/services; the risk/reward is asymmetric only if the theme translates into recurring revenue, not just backlog optics.
• Falsifier alert: if hyperscale customer commentary on water intensity keeps falling and there is no mention of incremental orders by the next two earnings cycles, fade the theme and reduce exposure to ECL/XYL/VEOEY.
• No options trade today unless there is a valuation reset; this is a slow-burn industrial theme, so paying up for short-dated calls is poor risk/reward absent a company-specific catalyst.
