With a significant compounded annual growth rate of 6.4% from 2025-2035, global water treatment systems market is poised to be valued at USD 26.8 Billion in 2035. The construction arrangements in the global water treatment systems market have their roots in various driving force factors such as high industrial wastewater discharge regulations and huge demands for potable water supply in urban areas. For example, Veolia Water Technologies in the year 2024 partnered with ArcelorMittal for the implementation of advanced zero liquid discharge (ZLD) systems for steel plants in Europe, thus, addressing stricter EU wastewater compliance.

In June 2025, Pentair plc launched its new Everpure H2Optimo Series, a smart commercial water filtration system designed for foodservice and hospitality sectors. The system integrates IoT-enabled monitoring for real-time water quality and predictive maintenance. John L. Stauch, President and CEO of Pentair, emphasized the move as part of their strategy to deliver “smarter, more sustainable water solutions” to meet evolving customer needs globally. This innovation enhances operational efficiency and expands Pentair’s footprint in the commercial water treatment segment.
Moreover, Pentair launched a new series of smart residential water filtration solutions in March 2025 in view of the rise in demand for clean drinking water from urban households across North America. These are some of the triggering forces that have accelerated global adoption of industrial and residential water treatment systems.
The enormous opportunities in global water treatment systems include smart water metering solutions, industrial sludge management technologies, and advanced membrane manufacturing. These further aid water utilities and industries with efficiency, regulatory compliance, and system integration. These neighboring markets promote synergistic growth as a whole that adds significant value to the water treatment solutions around the world.


Key players in the global water treatment systems market include prominent companies such Veolia Environment, SUEZ, Xylem Inc., Ecolab Inc., Pentair plc, and Other Key Players.
The water treatment systems market is moderately consolidated, with a handful of Tier 1 players that include Veolia, SUEZ, and Danaher Corporation, who lead through comprehensive portfolios and infrastructure projects of global scale. Tier 2 and 3 players, including Lenntech and Pure Aqua, meet local or specialized needs. Buyer concentration is moderate, spanning the industrial, municipal, and residential sectors. Supplier concentration is high because of reliance on advanced filtration technology, membrane components, and chemical formulations compliant with regulatory standards from a limited number of specialized manufacturers.
