Water Treatment Systems Market size was over USD 43.06 billion in 2024 and is projected to reach USD 115.71 billion by 2037, growing at around 7.9% CAGR during the forecast period i.e., between 2025-2037. In the year 2025, the industry size of water treatment systems is assessed at USD 45.78 billion..
The water treatment systems market is predicted to grow due to the growing demand to reduce water contamination. Many people around the world were alarmed by rising levels of water contamination. By mixing dangerous chemical compounds and microbes, more industrial activity is polluting the surface water. These dangerous substances are of immediate danger to human health. According to a report by World Health Organization (WHO), at least 1.7 billion people worldwide will be using feces-contaminated drinking water in 2022. The biggest threat to the safety of drinking water is microbiological contamination brought on by feces. Installation of water treatment devices in individual dwellings or buildings is encouraged by the lack of water treatment infrastructure at municipal water plants in several countries. Therefore, this factor is impacting the growth of the water treatment systems market.

Installation (Point-of-Use (PoU), Point-of-Entry (PoE))
In water treatment systems market, point-of-use segment is projected to account for revenue share of around 58% by 2037. The segment growth is propelled by the increase in water contamination. PoUs are essential for the treatment of drinking water in underdeveloped areas because they are easy to use, affordable, require little maintenance, and are grid-independent.
According to a 2023 UNESCO report, 3.6 billion people (46%) do not have access to securely managed sanitation, and 2 billion people (26%) do not have access to safe drinking water globally. These systems are of great use in health care settings, especially for the treatment of patients who have an impaired immune system. The segment for point-of-use water treatment systems is expected to increase significantly over the forecast period, as a result of various factors such as population growth, increased awareness about the benefits of water treatment, and technological advances in this area.
Technology Type (Reverse Osmosis, Distillation Systems, Disinfection Methods, Filtration Methods, Water Softeners)
By the end of 2037, reverse osmosis segment is anticipated to dominate water treatment systems market share of around 35%. To remove 99% of water impurities while offering the same quality as drinking water, RO systems are using innovative membrane filter technology. Therefore, water purification is frequently performed by such systems. They're considered to be the most efficient way of treating hard water. The reverse osmosis system is typically connected to a mechanical and activated carbon filter.
RO water purifiers are available in a variety of sizes and shapes, including wall-mounted, tabletop, under-sink, and under-the-counter models. To support the growth of this sector, reverse osmosis technology has a higher efficiency, a higher capacity, and a lower economic cost compared to other technologies.
According to a National Institutes of Health report, the groundwater in NCP has sufficiently high removal or rejection efficiency (91–98%) for important elements including TDS, hardness, alkalinity, silica, and significant ions (Ca2+, Mg2+, Na+, Cl−, and SO42−) for the RO stations now in operation.

APAC Market Statistics
Asia Pacific industry is likely to dominate majority revenue share of 36% by 2037. The region's rising levels of water contamination are to blame for the expansion. Also, it is expected that the region's limited access to a clean drinking water supply will contribute to the increased use of water treatment technology. Furthermore, the nation's point-of-use systems have become increasingly popular at home due to inadequate treatment infrastructure at municipal treatment facilities.
The water treatment systems market is poised to grow at a rapid rate in China led by the growing installment of water treatment systems in residential and commercial. Reverse osmosis, disinfection, and distillation systems are examples of water treatment systems that are predicted to see an increase in demand across a range of end-use industries due to the rapid expansion of industrial activity and rising levels of water pollution. For instance, about 70% of the nation's rivers and lakes are unsuitable for human use due to toxic human and industrial waste dumping, which has contaminated up to 90% of the groundwater in the nation.
In Korea, the water treatment systems market is projected to grow substantially during the forecast timeline. The market is growing in the nation owing to the several initiatives taken by the government to support water treatment and filtration processes. For instance, in 2023, South Korea declared the beginning of a new project to design wastewater treatment facilities that will automate management and operation through the use of artificial intelligence (AI) technologies.
The demand for water purifiers in both the household and commercial sectors is being driven by environmental concerns about single-use plastics and the carbon footprint of water purifying procedures. These factors are responsible for the market's rise in Japan.
North America Market Analysis
By 2037, water treatment systems market size for North America region is anticipated to cross USD 17 billion and will hold the second position owing to the high uptake of water treatment systems among consumers. Moreover, the expansion of the water treatment systems market is driven by the presence of large-scale commercial producers and their well-established distribution networks. The industrial share of water treatment systems (point of use) and water filter use are further driven by the strong growth of regional commercial sectors including banking, telecom, and IT.
The water treatment systems market is growing in the United States due to the growing adoption of various water treatment systems in the residential sector to treat wastewater. According to a recent report by the US Environmental Protection Agency, septic systems in the US provide service to over 60 million people. Septic or other decentralized treatment systems service about one-third of all new construction.
In Canada, the water treatment systems market is slated to grow significantly influenced by the growing population and surge in construction projects. For instance, Canada, which has more than 40 million citizens as of 2024, is ranked 37th in the globe in terms of population. It makes up around 0.5% of all countries worldwide.
