U.S. Water and Wastewater Treatment Technologies Market by Treatment Technologies Type (Membrane Separation & Filtration, Sludge Management Technology, Activated Sludge, Clarification) and Application - Forecast to 2035
Market Overview
The U.S. water and wastewater treatment technologies market was valued at $22.4 billion in 2024. This market is expected to grow at a CAGR of 6.4% during the forecast period to reach USD 43.8 billion by 2035 from an estimated USD 23.5 billion in 2025.
The growth of the U.S. water and wastewater treatment technologies market is driven by strict environmental regulations that require better treatment capabilities. There are also large federal and state infrastructure investment programs, expanding industrial sectors with specific water needs, and rising water scarcity that boosts demand for reuse technologies.
Moreover, the increasing use of membrane technologies and energy-efficient treatment systems is likely to create significant growth opportunities for companies in the U.S. water and wastewater treatment technologies market. However, high capital costs and complex regulatory compliance can limit market growth to some degree. The need to manage treatment waste and upgrade old infrastructure also poses ongoing challenges for the companies operating in this market.

Growing Advancements in Wastewater Treatment Technologies
The U.S. water and wastewater treatment industry is growing rapidly due to changing regulations, industrial growth, and new technologies. Federal infrastructure investments of over USD 50 billion by 2032 are helping speed up the use of modern treatment technologies in both municipal and industrial areas.
The implementation of stringent PFAS (per- and polyfluoroalkyl substances) regulations are greatly affecting more than 5,000 water systems in the country. The EPA's regulations introduced in 2024 set strict limits for several PFAS compounds. Compliance deadlines will stretch into 2031. This is creating a strong demand for treatment technologies that can effectively remove these long-lasting pollutants.
Simultaneously, growth in industries like semiconductors, pharmaceuticals, and energy is increasing the need for specialized wastewater treatment solutions. These solutions must address specific contaminants and operational needs. This situation benefits companies that provide integrated solutions for meeting regulations and improving efficiency.
Key Findings of the Study:
The Membrane Separation Technology Segment to Maintain Market Dominance Through 2035
The membrane separation technology segment is expected to maintain the largest share of the overall water and wastewater treatment technologies market in the U.S. This is primarily attributed to stringent regulatory requirements for emerging contaminants removal, growing semiconductor and data center applications requiring ultrapure water, and technological advances reducing energy consumption and improving membrane lifespan.
The Industrial Segment Positioned for Exceptional Growth
The industrial segment is expected to register the highest CAGR during the forecast period of 2025 to 2035. The growth of this segment is attributed to the rapid expansion of the semiconductor industry driven by CHIPS Act funding, explosive growth in AI data center cooling requirements, battery manufacturing expansion for electric vehicles, and increasing focus on water recycling and zero liquid discharge systems.
Competitive Landscape
The dynamics of the U.S. water and wastewater treatment technologies market have changed significantly over the past five years, especially due to major mergers among leading companies.
In May 2023, Xylem completed its acquisition of Evoqua Water Technologies in a stock deal worth about $7.5 billion. This merger formed the largest pure-play water technology company in the world, with a combined revenue of approximately $7.3 billion and over 22,000 employees globally. The merged portfolio provides complete treatment solutions across industrial, municipal, and specialty areas.
Strategic Developments and Market Positioning
-
Technology Leadership and Innovation Focus
In January 2025, DuPont decided not to spin off its Water Solutions division, keeping the unit that generates about $1.5 billion in revenue. The company leads in reverse osmosis and ion exchange technologies, focusing on tackling PFAS treatment issues and increasing demand for membrane technology.
- PFAS Litigation and Technology Shift: In 2024, 3M reached a settlement with U.S. public water suppliers to resolve PFAS contamination. The company plans to stop PFAS manufacturing by the end of 2025 and is investing more than $1 billion in new PFAS treatment technologies and filtration solutions, shifting its focus to remediation technologies.
Venture Investment and Emerging Players
In 2024, Xylem grew its corporate venture capital fund to $50 million, concentrating on innovations that address water scarcity, quality, and decarbonization.
Notable emerging companies attracting significant investment include:
- Oxyle, which raised $16 million for PFAS destruction technology
- StormHarvester, securing about €9.7 million for AI-driven wastewater management
- ZwitterCo obtained $58.4 million to expand advanced membrane technologies for industrial use.
