The global water treatment market size was valued at USD 65.1 billion in 2023 and is projected to reach USD 119.8 billion by 2032, registering a CAGR of 7.0% during the forecast period (2024-2032). The need to reduce contamination and the demand for virus-free products are driving the water treatment market growth. Water treatment enhances water quality to make it suitable for specific uses such as drinking, industrial processes, irrigation, and environmental applications. Water treatment removes contaminants and impurities from raw water or wastewater to meet quality standards and regulatory requirements.
The growing awareness of waterborne diseases such as diarrhoea, cholera, typhoid, amoebiasis, and hepatitis fuels the growth of the water treatment market. Furthermore, increased water use in various industrial sectors such as oil and gas, pharmaceuticals, and chemicals drives market growth. Industries are increasingly recognizing the importance of treating and managing water resources responsibly to meet regulatory standards and minimize environmental harm, driving demand for water treatment solutions and services.
However, water treatment unit installation and maintenance costs limit the market's growth. On the other hand, advances in water treatment technology, such as low-salt-rejection reverse osmosis (LSRRO), which have the potential to provide affordable and energy-efficient desalination of highly saline water, are expected to create numerous growth opportunities for the market in the future.
Growing global population and urbanization, combined with climate change effects such as droughts and decreased precipitation, exacerbate water scarcity. For example, The United Nations predicts that the world's population will reach 9.7 billion by 2050. Rapid urbanization, particularly in developing countries, drives up water demand for municipal, industrial, and agricultural purposes. This emphasizes the importance of efficient water treatment technologies for effectively utilizing limited water resources.
Additionally, access to clean and safe water is our world's "great connector" and critical to promoting peace, according to the 2024 United Nations World Water Development Report released on World Water Day. According to the report, 2.2 billion people worldwide still lack safe drinking water, while 3.5 billion lack safe sanitation. As of 2022, roughly half of the world's population faced at least temporary severe water scarcity. By 2024, 1.8 billion people will live in regions or countries with absolute water scarcity, defined as less than 500 cubic meters per person per year.
Moreover, water scarcity increases the demand for advanced water treatment technologies such as desalination, membrane filtration, and water reuse systems. Companies invest in technologies that improve water efficiency, reduce energy consumption, and treat wastewater for reuse. Furthermore, governments enact stricter regulations to manage water resources sustainably, encouraging investment in water treatment infrastructure and technologies.
High capital costs refer to the significant initial investments to plan, build, and equip water treatment facilities with advanced technologies. These costs include infrastructure development, treatment equipment procurement, system installation, and initial operational setup.
Additionally, industrial water treatment is a complex set of technologies and systems that serve a variety of industries and applications. Regarding industrial water treatment systems, lower flow rates mean lower capital costs. While this rule applies to most systems, the flow rate can be more critical for certain technologies than others. For most industrial applications, a 150,000 GPD WWTS would cost between USD 500,000 and USD 1.5 million, which includes all design, engineering, equipment, installation, and startup. More complex streams, higher flow rates, and higher effluent quality standards will all increase the system cost.
Furthermore, a raw water treatment system with a 200-1000 gallons capacity per minute (GPM) can range from USD 975,000 to USD 3 million, depending on water quality and flow rate. A 100 GPM cooling tower water treatment system can cost between USD 50,000 and USD 250,000, with additional costs for softening and desilication. Continued innovation in water treatment technologies, cost-effective solutions, and financing mechanisms are critical for breaking through capital cost barriers.
Smart water management combines IoT (Internet of Things), AI (Artificial Intelligence), and data analytics to improve water treatment and distribution systems' efficiency, dependability, and sustainability. This method enables real-time monitoring, predictive maintenance, and optimization of water resources, thereby increasing operational efficiency and lowering costs. Schneider Electric engineers, for example, used smart water management to reduce water consumption by 57% in a plant, improve waste optimization by 64%, and reduce CO2 emissions by 61%.
Additionally, ABB announced the acquisition of Canadian company Real Tech, a leading supplier of innovative optical sensor technology for real-time water monitoring and testing. ABB will expand its strong presence in the water segment and add optical technology, which is critical for smart water management, to its product portfolio through the acquisition. Unlike traditional water quality measurement, which can be time-consuming, Real Tech's product portfolio delivers critical measurements in real time. This improves process control and ensures continuous water quality assurance. Real Tech's patented solutions encompass the entire digital water value chain for water quality monitoring, focusing on data generation and analytics.
Hence, continued investment in IoT, AI, and data analytics solutions will be critical for utilities, municipalities, and industries seeking to optimize water resources, improve service delivery, and effectively mitigate water-related risks. Embracing smart water management solutions can have long-term benefits for communities worldwide, such as increased resilience to climate impacts and improved water security.
