Ozone, advanced oxidation and membrane bioreactors are increasingly used for micropollutant removal. Capacity expansion in biologics and vaccine production boosts demand for validated, automated water systems with continuous monitoring.

• Microelectronics: Microelectronics holds 4% of the water market but has the highest purity requirements of any application. Semiconductor fabs need ultrapure water with very low ionic, organic and particle content, produced through multi-stage reverse osmosis, ion exchange, degasification and ultraviolet oxidation. Large fabs consume enormous volumes of water, which pushes operators toward aggressive recycling and reclaim of rinse water. Wastewater from etching and polishing contains fluoride, copper and ammonia that need specialized treatment. New fab construction in the United States, Taiwan, South Korea and Japan is lifting investment in this segment.

• Other: Other applications account for 4% of the water market and include commercial buildings, hospitality, data centers, textiles, chemicals, steel and agriculture-related processing. Cooling tower treatment in data centers and commercial properties is a notable growth area, as operators seek to control scaling, corrosion and legionella while reducing makeup water. Textile and metal finishing facilities require color, heavy metal and chemical oxygen demand removal. Packaged plants and point-of-use systems serve decentralized users, and water-as-a-service contracts help smaller customers access advanced treatment without heavy upfront capital.

MARKET DYNAMICS

Driving Factor

Rising water scarcity and stricter discharge regulation

Water scarcity and tighter regulation are the strongest forces behind the water market. Around 2.2 billion people still lack safely managed drinking water, and many regions face groundwater depletion, saline intrusion and drought. Governments are responding with tougher standards for emerging contaminants, nutrient discharge and industrial effluent, which compels utilities and factories to upgrade treatment capacity. Population growth, urbanization and industrial expansion add pressure on limited freshwater sources. Corporate water stewardship targets further motivate investment in recycling, efficiency and monitoring technologies, creating sustained demand for membranes, disinfection, biological treatment and digital management tools.

Drivers impact analysis*

Restraining Factor

High capital and operating costs of advanced treatment

Advanced treatment systems require significant upfront investment and continuing spending on energy, chemicals, membranes and skilled labor. Small municipalities and emerging economies often lack the financing and tariff structures to fund plant upgrades, which delays projects. Reverse osmosis and thermal desalination consume large amounts of electricity, and rising power prices can erode project economics. Membrane replacement, sludge disposal and brine handling add recurring costs that buyers must plan for over the asset life. Lengthy permitting and procurement cycles also slow deployment, leading some buyers to postpone modernization or choose lower-cost conventional processes.

Restraints impact analysis*

Expansion of water reuse and zero liquid discharge

Opportunity

Water reuse is opening major opportunities as cities and industries look for drought-resistant supply. Treated wastewater can serve irrigation, cooling, industrial processes and, with advanced purification, drinking water. Technology providers can offer membrane bioreactors, reverse osmosis, advanced oxidation and ultraviolet disinfection as integrated reuse packages. Zero liquid discharge systems for refining, power, mining and chemicals are gaining ground as regulators restrict effluent release. Data centers and semiconductor fabs are emerging as new reuse customers because of heavy cooling and rinse water needs. Build-own-operate and water-as-a-service models lower upfront spending and create recurring income for suppliers.

Aging infrastructure and persistent contaminants

Challenge

Aging pipes, pumps and treatment plants remain a serious challenge for the water market. Leakage, main breaks and intermittent supply waste treated water and undermine service quality, while replacement programs require large and prolonged capital commitments. Persistent contaminants such as PFAS, microplastics and pharmaceutical residues are costly to remove, and 44% of household wastewater is still not safely treated worldwide. Shortages of skilled operators complicate the running of sophisticated systems, and cybersecurity risks grow as plants adopt remote monitoring. Suppliers must therefore deliver reliable, easy-to-operate technologies with strong service support.
