Water-Wastewater Treatment Global Market Report 2026

Water-wastewater treatment refers to the process of eliminating physical, chemical, and biological contaminants from water to make it appropriate for reuse or safe release into the environment. It includes a sequence of treatment procedures that help minimize pollutants such as suspended solids, organic matter, pathogens, and hazardous chemicals. Water-wastewater treatment supports the protection of natural water resources and helps preserve environmental and public health standards.

The primary offerings of water-wastewater treatment include treatment technologies, equipment and machinery, consumables and chemicals, and aftermarket services and maintenance. Treatment technologies refer to advanced systems and methods utilized to remove contaminants and ensure safe water quality across different treatment stages. The different operations include treatment plants and operation and maintenance services and the various process types include physical treatment, chemical treatment, biological treatment, thermal treatment, and electrochemical treatment. They find applications involved are drinking water treatment, wastewater and sewage treatment, industrial effluent management, and recycled and reuse water systems, and they are utilized by end users including municipalities and utilities, industrial enterprises, agricultural facilities, and commercial establishments.

Tariffs are influencing the water-wastewater treatment market by increasing the cost of imported treatment technologies, equipment, and chemical consumables such as membrane filtration systems, pumps, and disinfection chemicals required for efficient water processing. This is slowing project execution and infrastructure upgrades, particularly in import-dependent regions such as Asia-Pacific and Latin America where municipal and industrial treatment expansion is ongoing. Equipment-intensive segments such as advanced filtration systems and membrane modules are most affected due to global supply chain dependencies. However, tariffs are also encouraging local manufacturing of treatment equipment, regional sourcing of chemicals, and increased investment in domestic water infrastructure ecosystems, thereby improving long-term supply resilience and cost optimization.

This water-wastewater treatment market research report delivers a complete perspective of everything you need, with an in-depth analysis of the current and future scenario of the industry.

The water-wastewater treatment market size has grown rapidly in recent years. It will grow from $349.6 billion in 2025 to $395.97 billion in 2026 at a compound annual growth rate (CAGR) of 13.3%. The growth in the historic period can be attributed to rising industrialization leading to higher wastewater generation, increasing urban population driving municipal water treatment demand, tightening environmental regulations on effluent discharge standards, expansion of centralized sewage treatment infrastructure, growing awareness of waterborne disease prevention and sanitation.

The water-wastewater treatment market size is expected to see rapid growth in the next few years. It will grow to $657.12 billion by 2030 at a compound annual growth rate (CAGR) of 13.5%. The growth in the forecast period can be attributed to increasing adoption of smart water management systems with ai analytics, expansion of decentralized wastewater treatment solutions in rural and remote areas, rising investments in water reuse and recycling infrastructure, integration of advanced sensor-based real-time monitoring systems, growing demand for sustainable and energy-efficient treatment technologies. Major trends in the forecast period include rising adoption of ai-enabled predictive maintenance systems in wastewater treatment plants, increasing deployment of iot-based smart water quality monitoring networks, expansion of energy-efficient membrane filtration and advanced treatment technologies, growing implementation of circular water reuse and zero-liquid-discharge systems, integration of digital twin models for real-time optimization of treatment operations.

The increasing water scarcity is expected to propel the growth of the water-wastewater treatment market going forward. Water scarcity refers to the condition in which the available freshwater resources are inadequate to meet the demands of a region or population. The growing water scarcity is driven by climate change-induced declines in rainfall, which disturb natural water availability and limit the replenishment of freshwater resources. Water-wastewater treatment helps reduce water scarcity by facilitating the recycling and reuse of treated wastewater, thereby enhancing the availability of usable water resources and decreasing reliance on freshwater sources. For instance, in November 2024, according to the United Nations Educational, Scientific, and Cultural Organization, a France-based non-profit organization, roughly half of the world's population experiences severe water scarcity for at least part of the year, and millions lack access to safely managed water resources. With 3.6 billion people currently facing water shortages, projected to exceed 5 billion by 2050. Therefore, the increasing water scarcity is driving the growth of the water-wastewater treatment market.

Leading companies operating in the water-wastewater treatment market are focusing on developing advanced solutions, such as next-generation ultrafiltration (UF) membrane technologies, to improve contaminant removal efficiency, reduce energy consumption, and enhance operational reliability in water purification systems. Next-generation ultrafiltration (UF) membrane technologies refer to advanced filtration systems designed to effectively remove suspended solids, bacteria, and macromolecules from water while improving energy efficiency, permeability, and operational performance in water and wastewater treatment. For instance, in March 2023, DuPont, a US-based science and technology company, launched DuPont Multibore PRO, a next-generation ultrafiltration (UF) membrane developed to improve filtration performance and operational efficiency in municipal and industrial water treatment applications. The solution improves fouling resistance, enhances membrane durability, and lowers lifecycle costs, enabling water utilities and industries to achieve more dependable and energy-efficient water purification and wastewater treatment results.

In May 2023, Xylem Inc., a US-based provider of water and wastewater treatment technologies and services, acquired Evoqua Water Technologies for approximately $7.5 billion.
