The COVID-19 pandemic had a moderate effect on the industry owing to the disruptions in the water supply network globally.

U.S. water treatment systems market size, by installation, 2020 - 2030 (USD Billion)

As a result of the water crisis, increased water pollution, and deaths from water-borne diseases, the demand for water treatment systems witnessed significant growth. Growing population, strong economic growth, rising household formations, and low mortgage rates are expected to be the key factors driving the growth in residential construction. Through the Safe Drinking Water Act of 1974, the Environment Protection Agency (EPA) has set standards for the quality of drinking water supply, and along with its partners, the agency implements numerous financial and technical programs to safeguard drinking water quality.

The Clean Water Act establishes the fundamental framework for controlling the discharge of pollutants into waters and for regulating surface water quality standards. Thus, growing emphasis on the quality of water will drive the market for water treatment systems in the U.S. The increasing levels of contamination have resulted in the rising adoption of water treatment systems, thereby boosting industry growth in the country. The EPA is still carrying out administrative orders to ensure safe drinking water through public water systems.

Moreover, the announcement of the Drinking Water & Wastewater Infrastructure Act of 2021 in May 2021 by the U.S. government with funding of USD 35 billion is also expected to create opportunities for this market. The U.S. government is undertaking several initiatives to improve its public infrastructure. For instance, in June 2021, the U.S. Department of Transportation announced a USD 905.3 million investment in infrastructure development projects in the country through the discretionary grant program Infrastructure for Rebuilding America (INFRA) Thus, growing commercial projects in the country are expected to drive the demand for water treatment systems.

Installation Insights

The point-of-use installation segment dominated the industry in 2021 and accounted for the largest share of more than 74.00% of the overall revenue. PoU systems are essential for treating water in underdeveloped areas as they are simple to use, inexpensive, require minimal maintenance, and are grid-independent. These systems are extremely useful in medical settings, particularly when dealing with patients having impaired immune systems. The market for point-of-use water treatment systems is anticipated to expand significantly over the coming years as a result of various factors including rising water contamination, growing population, increasing awareness about the advantages of water treatment, and technological advancements in the water treatment sector.

Point of Entry (PoE) systems are often huge and robust and can last for many years without needing any significant maintenance. These systems are affordable, however, to extend their operating life, regular cleaning or maintenance is needed. PoE water treatment method has been widely used for many years in individual commercial operations, such as lodges, hotels, restaurants, schools, and other public facilities. The key benefits of PoE for small communities include cheaper & quicker installation, easier implementation, and simpler maintenance & operation. For instance, to guarantee clean drinking water through public water systems, the Environmental Protection Agency of the U.S. is putting out administrative orders.

Technology Insights

The reverse osmosis systems technology segment dominated the global industry in 2021 and accounted for the largest share of more than 30.50% of the overall revenue. Reverse osmosis can get rid of numerous types of suspended or dissolved bacterial and amoebic particles present in the water. A reverse osmosis system includes carbon and sediment filtration. In the RO system, carbon filters remove chlorine, bad taste, and odor and sediment filters remove debris and dirt. The distillation systems segment also accounted for a significant revenue share in 2021. Distillation units are installed as point-of-use units at the faucet rather than being used to treat all the water entering the house because they only produce a small amount of treated water.

Point-of-use distillation units clean water, minimize the number of toxic metals, and get rid of some organic contaminants. Disinfection systems include the use of chlorine dioxide, chlorination, ozone, ultraviolet light, and chloramines. UV water disinfection technology uses ultraviolet light with a wavelength of 253.7 nanometers to disinfect bacteria, viruses, algae, and molds. This technology destroys microorganism DNA, rendering them dead or unable to multiply. Filtration is the process of removing suspended solids from a liquid by forcing the latter to move through the pores of a filter or a membrane with pores. The size and quantity of the contaminants affect the filtration procedure. 3M, Calgon Carbon Corp., Panasonic, and DuPont are some of the manufacturers of filtration methods.

End-use Insights

The residential end-use segment is estimated to register the fastest growth rate of more than 9.00% during the projected period. The product demand in the residential segment is anticipated to be driven by rising concerns about new contaminants and demand for high-quality drinking water. It is also anticipated to expand quickly due to the demand for drinking water that has been treated to remove pathogenic bacteria, biodegradable organics, unpleasant taste, odor, and discoloration. Residential applications are a large consumer group in the market for water treatment systems. Over the past years, the drinking water quality in developing regions of the world, including North America and Europe, has witnessed high levels of contamination, primarily due to lax cleaning procedures and the percolation of unhealthy constituents into the water table.

Global water treatment systems market share, by end-use, 2021 (%)

These aforementioned factors will drive product demand in the residential sector. The commercial end-use segment is projected to register the second-fastest CAGR from 2022 to 2030. The water treatment needs in malls, offices, commercial spaces, restaurants, hotels, manufacturing plants, schools, laboratories, and other organizations with high-volume consumption of high-quality water are largely met by commercial water treatment systems. Growing health consciousness among young populations and society’s upper classes can be linked to the rising adoption of water purification systems. The probability of water-borne illnesses like cholera and cryptosporidiosis, among others, is reduced by access to clean drinking water. The public's awareness of health issues and benefits of living a healthy lifestyle has increased noticeably with the advent of the information era. The adoption of water treatment technologies for preventing the spread of water-borne diseases is a major outcome of this awareness.

Regional Insights

The Asia Pacific region led the global industry in 2021 and accounted for the maximum share of more than 36.00% of the global revenue. The growth can be attributed to the increased water pollution in the region.
