ROCKVILLE, Md., September 9, 2026 — The Industrial Water Treatment Market is projected to grow from USD 50.5 billion in 2026 to USD 84.6 billion by 2036 at a 5.3% CAGR, according to Fact.MR analysis, as tighter discharge requirements and new industrial water-efficiency initiatives increase demand for treatment and recycling systems.

The timing is significant for industrial operators. In February 2026, the U.S. Environmental Protection Agency finalized a rule adding approximately 200 PFAS compounds to the Toxics Release Inventory, increasing reporting requirements for industrial facilities. In the same period, Ecolab integrated its acquired Ovivo Electronics ultrapure water business to target semiconductor and data center demand, while Veolia and Suez secured major water contracts in India.

Regulation and Water Reuse Push Demand

Industrial facilities are facing a more complex water management requirement. Fact.MR identifies increasing industrial water consumption, stricter wastewater discharge regulations, and rising demand for water reuse and recycling as core market drivers.

The market was valued at USD 50.5 billion in 2025 and is estimated at the same USD 50.5 billion in 2026, before reaching USD 84.6 billion by 2036. That represents USD 34.1 billion in absolute dollar growth between 2026 and 2036.

Technology is also changing the spending mix. Fact.MR describes the Industrial Water Treatment Market as a mature, compliance-anchored segment in which advanced systems with real-time monitoring, recycling, and zero-liquid-discharge capabilities are gaining attention.

In January 2026, Ecolab launched its Water Use Efficiency Index, following its December 2025 acquisition of Ovivo Electronics’ ultrapure water business. The move targets semiconductor and data center applications, where ultrapure water requirements are becoming a larger part of industrial water planning.

Industrial Water Treatment Market Favors Chemical Treatment

Chemical treatment is expected to account for 28% of the market in 2026, according to Fact.MR. The technology is used for coagulation, flocculation, disinfection, and pH adjustment across industrial applications.

Chemical treatment remains widely used because it can address different water-treatment requirements and can be less expensive than some advanced options, including reverse osmosis and UV treatment.

The chemical industry is also projected to hold a 28% market share in 2026. Water-intensive operations such as cooling, heating, washing, and dissolving create continued treatment requirements, while effluent regulations increase the need for controlled wastewater management.

The Industrial Water Treatment Market covered in this report includes technologies and services used to clean, condition, and manage water in industrial processes. The scope includes physical, chemical, biological, membrane, advanced oxidation, and sludge treatment technologies.

India Leads Country Growth

India is projected to record the fastest growth among the countries assessed, with a 7.3% CAGR through 2036. Fact.MR attributes this growth to rapid industrialization, rising water usage, water scarcity concerns, and increasing regulatory pressure on industrial wastewater.

China follows at 6.7% CAGR, supported by its large manufacturing base and environmental initiatives. Brazil is projected to grow at 5.6%, while Germany and the USA are expected to record CAGRs of 4.6% and 4.4%, respectively.

Major Industry Moves Add Pressure

Recent developments show how regulation and investment are influencing industrial water management.

The U.S. Environmental Protection Agency finalized its PFAS reporting rule in February 2026. The development adds approximately 200 PFAS compounds to the TRI and affects industrial sectors including chemicals, plastics, and synthetic fibers.

Ecolab’s acquisition of Ovivo Electronics’ ultrapure water business also points toward growing water requirements in advanced manufacturing. The transaction closed in December 2025, with integration completed by February 2026.

India has emerged as another focal point. In February 2026, Veolia secured 15-year contracts for Mumbai’s Bhandup and Panjrapur plants, covering a combined 2,910 MLD, while Suez secured a 25-year, €456 million contract for Salem, Tamil Nadu.

Those projects incorporate digital platforms and zero-liquid-discharge technologies for industrial clusters.

Industry Leaders Focus on Water Efficiency

The competitive landscape includes Veolia Environnement S.A., Ecolab Inc., Xylem Inc., Pentair plc, Kurita Water Industries Ltd., Solenis LLC, SWA Water Australia Pty Ltd., WOG Group, Kemira Oyj, and Feralco AB.

These companies compete across chemical treatment, filtration, membranes, wastewater management, and specialized industrial water services.

Inge Delobelle, Executive Vice President and Divisional CEO, Industry division, at Grundfos, said:

“In a world where it is more critical than ever that we treat, reduce and reuse water with great care, building a strong water treatment business is pivotal.”

Fact.MR Principal Consultant Shambhu Nath Jha said:

“The Industrial Water Treatment Market continues to evolve with rising environmental and regulatory pressures. As industries face challenges related to water conservation, the demand for advanced and sustainable water treatment solutions is expected to rise significantly.”

Jha added that chemical treatments and membrane technologies are expected to remain core components, while more energy-efficient and cost-effective solutions represent an area for future development.
