What Is Covered Under Decentralized Water Treatment Market?

Decentralized water treatment involves placing water or wastewater treatment facilities closer to the water supply or demand point rather than centralizing them in distant treatment plants. This approach aims to offer more localized and efficient treatment solutions, resulting in cost reduction, enhanced flexibility, improved sustainability, and increased control over water management. The main technologies of decentralized water treatment are membrane technology, thermal technology, and others. Membrane technology refers to the use of membranes to filter and purify water at a local or smaller scale, typically for individual buildings, communities, or remote locations. Point of use (POU), point of entry (POE), and small-scale systems are used for wastewater treatment, effluent treatment, and water treatment applications by municipal and industrial end users.

What Is The Decentralized Water Treatment Market Growth Forecast?

The decentralized water treatment market size is expected to see rapid growth in the next few years. It will grow to $37.8 billion in 2030 at a compound annual growth rate (CAGR) of 13.8%. The growth in the forecast period can be attributed to increasing demand for decentralized water treatment in urban and rural areas, advancements in membrane and electrochemical technologies, integration of ai and iot for smart water management, emphasis on sustainable and energy-efficient treatment methods, expansion of industrial and commercial water treatment applications. Major trends in the forecast period include increasing adoption of membrane-based filtration systems, deployment of compact point-of-use (pou) treatment units, integration of smart sensors for real-time water quality monitoring, growing implementation of small-scale, modular treatment plants, rising use of advanced thermal and biological treatment technologies.

What Is The Driver Of The Decentralized Water Treatment Market?

The rising demand for freshwater is expected to propel the growth of the decentralized water treatment market going forward. The demand for freshwater is increasing due to growing populations, urbanization, industrialization, agricultural expansion, climate change, environmental degradation, and inefficient water use. Decentralized water treatment helps freshwater by providing localized purification solutions, reducing strain on centralized systems, and improving access to clean water in remote or underserved areas. For instance, in March 2023, according to the World Economic Forum (WEF), a Switzerland-based non-governmental organization, in 2030, global freshwater demand is projected to outstrip supply by 40%. Therefore, the rising demand for freshwater is driving the growth of the decentralized water treatment industry.

Global Decentralized Water Treatment Market Trends and Insights

Major companies operating in the decentralized water treatment market are developing innovative technologies, such as mobile water treatment units, to enhance wastewater reuse at a lower cost. A mobile water treatment unit is a portable system designed to purify and treat water on-site, making it suitable for drinking, industrial use, or environmental applications in remote or emergency situations. For instance, in May 2024, Nijhuis Saur Industries, a Netherlands-based water technology company, launched the Grey Water Treatment 2.0 solution, an innovative decentralized water management system that enables industries and municipalities to locally treat grey water such as rainwater, surface water, and shower water for reuse in applications such as toilet flushing and irrigation. This system promotes circular water management by transforming typically wasted water into a valuable resource. Designed for efficiency, the unit can operate in a single shift, providing quick access to treated water while significantly reducing the demand for freshwater by at least 30%.

What Are Latest Mergers And Acquisitions In The Decentralized Water Treatment Market?

In January 2024, Saur, a France-based company specializing in water and leisure management, acquired Natural Systems Utilities (NSU) for an undisclosed amount. The acquisition is aimed at leveraging the strengths of both companies to foster new synergies and support the commercial and residential building markets in the Americas and Europe.
