Data Center Water & Wastewater Treatment Equipment Market

The data center water and wastewater treatment equipment market is expected to expand from USD 3.30 billion in 2026 to USD 5.90 billion by 2031, with a CAGR of 12.3% during 2026-2031. The market is experiencing rapid growth due to the rising number of data center deployments, increased use of water for cooling, and a growing emphasis on sustainable water management practices. Data centers need advanced water treatment solutions to efficiently handle cooling water, prevent corrosion and scaling, supply high-purity water, and recycle wastewater. The market encompasses various products, including treatment chemicals, conditioners (for high purity water), filtration, disinfection systems, and other specialized equipment for different data center types—such as hyperscale, colocation, enterprise, and edge facilities. The adoption of liquid cooling technology and tightening environmental regulations worldwide—aimed at sustainability and corporate responsibility—are also fueling investments in technologies that enable wastewater reuse, recovery, and efficient treatment.

Veolia (France), Ecolab Inc. (US), Xylem (US), Solenis (US), Saltworks Technologies Inc. (Canada), Aquatech International LLC (US), Kurita America Inc. (US), Gradiant (US), Lenntech B.V. (Netherlands), IDE (Israel) are the key players operating in the market. Leading companies are focused on technological innovation, portfolio expansion, strategic partnerships, and sustainability-driven solutions to strengthen their market position. These players are developing advanced membrane systems, high-purity water treatment technologies, digital monitoring platforms, and water reuse solutions to meet increasing data center water-efficiency requirements. Companies are also expanding their presence through collaborations with data center operators, engineering firms, and cooling technology providers to integrate customized treatment solutions. Additionally, manufacturers are investing in research and development for energy-efficient, low-chemical, and zero-liquid-discharge technologies to meet regulatory and environmental goals. Geographic expansion, acquisitions, and development of integrated water management platforms are further supporting long-term growth and competitive differentiation.
