Water Treatment Systems Sector: Growth Drivers and Challenges
Growth Drivers
- Growing implementation of laws and regulations - Fresh water makes up only three percent of the water on Earth and just 1.2% of that can be consumed as drinking water. Therefore, the increasing implementation of various laws and legislation to ensure the supply of safe drinking water to the masses is fueling water treatment system market growth.
For instance, The United States' drinking water quality is safeguarded under the Safe Drinking Water Act (SDWA). In addition to this, by 2024, every household in rural India is expected to have access to sufficient and clean drinking water via individual tap connections due to the Jal Jeevan Mission.
- Increasing demand for advanced water treatment solutions - Global sales of water treatment systems have surged due to the introduction of novel technologies and their integration into various systems, including RO+UV systems.
For instance, by introducing a line of fashionable, distinctive, and high-end goods, Blue Star Limited, the top air conditioning and commercial refrigeration firm in India, has announced its debut in the home water purifier market. The company's initial product offering will be household water purifiers; over time, it will expand to include commercial water filtration devices.
- Increased integration of IoT in water supply systems - The entire infrastructure for the supply and distribution of water is monitored by the Internet of Water. Because it offers residents of rural and remote locations a reliable water supply during these water-scarce times, the Internet of Things is a disruptive force for water treatment utilities.
For instance, the introduction of the "O&M Support Digital Solution" was announced by Hitachi, Ltd. By using digital technologies like artificial intelligence (AI) and the Internet of Things (IoT) to collect and analyze a variety of data about the operations of the water supply and sewerage business, this service will help ensure stable operations of plants. Future developments in water treatment systems market are anticipated to increase the rate at which potable water is produced, making it easier to supply the expanding population.
Challenges
- Increased operational and maintenance costs - In addition to their original capital expenses, water treatment systems often incur continuing operating and maintenance costs for things like energy usage, chemical treatment, membrane replacement, and system monitoring. The total cost of ownership (TCO) of water treatment systems can build up over time for large-scale installations. Therefore, this factor may act as a barrier to the growth of the water treatment systems market.
Growing concern regarding aging infrastructure - The majority of wealthy nations struggle with the issue of aging infrastructure. These nations still employ antiquated water treatment infrastructure that was constructed decades ago. To upgrade and reinstall these outdated infrastructures, significant financial outlays are required. Therefore, this factor may hinder the growth of the water treatment system market.

Water Treatment Systems Segmentation
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.
