The Global Water Treatment Equipment Market was valued at USD 72.5 billion in 2025 and is estimated to grow at a CAGR of 6.2% to reach USD 131.7 billion by 2035.
The market is experiencing expansion driven by rising concerns over water scarcity, tightening global regulations on water quality, and growing demand for efficient purification systems across industrial applications. Increasing pressure on industries to ensure safe and reusable process water is further strengthening the adoption of advanced treatment solutions. Consolidation within the industry through mergers and acquisitions is also accelerating technological progress, particularly in membrane-based filtration and separation technologies. These developments are enabling companies to expand their presence across multiple end-use sectors, including chemicals, food and beverage production, pharmaceuticals, and municipal water systems. At the same time, traditional treatment approaches are being replaced by smart systems that integrate sensors, automation, and digital monitoring capabilities. These modern solutions improve operational efficiency, enhance water quality control, and support energy-efficient treatment processes. Rapid urban development, increasing adoption of water recycling initiatives in developed regions, and growing infrastructure investments in emerging economies are further reinforcing demand for advanced water treatment equipment globally.
The membrane systems segment reached USD 18.7 billion in 2025 and is projected to grow to USD 35.8 billion by 2035. This segment is gaining strong traction due to its high separation efficiency and ability to deliver superior water purification results. Its capability to eliminate dissolved impurities makes it highly suitable for advanced water reuse applications as well as desalination processes, strengthening its role in modern water treatment systems.
The reverse osmosis segment accounted for 31% share in 2025 and is expected to rise to 32.4% by 2035. Growth in this segment is supported by its strong performance in desalination, industrial water reuse, and high-purity water production applications. Its ability to effectively remove a wide range of contaminants makes it a preferred technology for both municipal and industrial water treatment systems.
United States Water Treatment Equipment Market held a 76% share in 2025, supported by stringent water quality regulations enforced by environmental authorities at both the federal and state levels. Increasing implementation of industrial water recycling programs and expansion of advanced manufacturing activities are further driving demand in the country. Growing investments in smart water infrastructure and digital monitoring systems are also enhancing the adoption of automated treatment technologies and advanced membrane solutions.
Key companies operating in the Global Water Treatment Equipment Market include Pentair, Veolia Water Tech, Xylem Inc., Suez, Grundfos, ITT Inc., DuPont Water, Ovivo Inc., AO Smith, Culligan, Ecowater, Kurita Europe, Pall (Danaher), Parkson, SAMCO Technologies, Smith & Loveless, and Trojan (Veralto). Companies in the Water Treatment Equipment Market are focusing on strengthening their competitive position through continuous technological advancement and system innovation. Many players are investing heavily in smart water solutions that integrate automation, IoT-enabled sensors, and real-time monitoring capabilities to enhance operational efficiency. Expansion of membrane-based technologies and advanced filtration systems remains a key strategic priority, enabling improved treatment performance and broader application coverage. Strategic mergers and acquisitions are also being used to expand geographic reach and strengthen technological capabilities. Firms are increasingly targeting industrial water reuse and sustainability-focused solutions to meet tightening environmental regulations.
