Water and Wastewater Treatment Equipment Market: Growth, Trends, and Outlook (2025–2032)

Market Overview

The global Water and Wastewater Treatment Equipment Market was valued at USD 43.79 Billion in 2025 and is projected to reach nearly USD 71.81 Billion by 2032, expanding at a CAGR of 7.32% during the forecast period. This growth is driven by increasing concerns over water scarcity, rising industrialization, stringent environmental regulations, and the growing need for sustainable water management systems.

Wastewater treatment involves removing contaminants from used water and converting it into reusable or environmentally safe effluent. With the rapid expansion of urban populations and industrial activities, the demand for advanced treatment solutions in both municipal and industrial sectors has increased significantly. Governments and private organizations are investing heavily in modern water infrastructure to ensure safe water availability and environmental protection.

Market Dynamics

Shortage of Freshwater Resources

Global freshwater scarcity remains one of the most critical challenges impacting water management. According to international organizations, over one-fifth of the world’s population lives in water-stressed regions, while many others lack financial access to clean water sources. Countries such as India and China face increasing pressure due to high population growth and limited water availability.

These challenges have accelerated the adoption of advanced technologies such as desalination, wastewater recycling, and water reuse systems. Manufacturers are increasingly focusing on alternative water sources, which is expected to strengthen market growth in the coming years.

High Installation and Operational Costs

Despite its benefits, water treatment infrastructure requires substantial capital investment. Equipment procurement, installation, energy consumption, and maintenance costs remain high, especially for developing and underdeveloped regions. Technologies such as UV disinfection, ozonation, and desalination systems are often unaffordable for small-scale industries and low-income countries.

Additionally, treatment plants consume significant energy, increasing operational expenses. These cost-related challenges act as restraints on market expansion, particularly in economically weaker regions.

Rising Demand for Energy-Efficient Systems

Energy efficiency has become a major focus in modern water treatment solutions. With growing concerns over energy depletion and environmental impact, industries and municipalities are adopting low-energy and eco-friendly systems.

Membrane-based technologies, including reverse osmosis (RO) and membrane bioreactors (MBR), play a crucial role in promoting water and energy sustainability. These systems offer high efficiency, compact design, and flexibility, making them suitable for various applications. Ongoing innovations aimed at improving affordability and energy performance are expected to create new growth opportunities.

Aging Water Infrastructure

Many developed countries are facing challenges related to aging water treatment facilities built decades ago. These outdated systems often lack efficiency and reliability, requiring major upgrades and replacements. Large investments are being directed toward modernizing infrastructure in regions such as Europe and North America.

At the same time, several developing countries are still in the early stages of building basic water infrastructure. The need for large-scale rehabilitation and modernization projects is expected to drive long-term market demand.

Market Segment Analysis

By Type

The market is segmented into Filtration, Disinfection, Adsorption, Desalination, Testing, and Others. Among these, the desalination segment is expected to witness the fastest growth during the forecast period. Increasing dependence on seawater and saline water sources is driving the adoption of desalination technologies, particularly in water-scarce regions.

By Derivative

Based on derivative, the market is categorized into Municipal, Industrial, and Others. In 2025, the municipal segment dominated the market, accounting for nearly 66% of total revenue. Rising urbanization, increasing residential demand, and stricter wastewater disposal regulations are key factors supporting this segment’s growth.

The industrial segment, including oil & gas, chemicals, food & beverages, and pulp & paper, is also expected to witness steady expansion due to rising compliance requirements.

By Process

The market is divided into Primary, Secondary, and Tertiary Treatment. In 2025, tertiary treatment held the largest share, contributing about 43% of total revenue. This process focuses on removing nutrients such as phosphates and nitrates using advanced filtration and adsorption methods.

Primary treatment involves sedimentation and removal of large solids, while secondary treatment uses biological and oxidation processes to eliminate organic matter.

By Equipment

Based on equipment, the market includes Membrane Separation, Biological, Disinfection, Sludge Treatment, and Others. The membrane separation segment led the market in 2025, driven by high filtration efficiency and compact design.

Sludge treatment equipment is expected to grow rapidly, supported by increasing demand for effective waste management solutions and environmental safety.
