The combined U.S. market for advanced drinking water technologies — made up of membrane filtration, ozone disinfection, UV irradiation, and novel oxidation processes — is estimated at nearly $1.9 billion in 2011 and is growing at a compound annual growth rate (CAGR) of 8.2 percent through 2016, according to a report by CompaniesAndMarkets.com. Membrane technology for municipal drinking water is valued at $1.4 billion in 2011, with a predicted compound annual growth rate (CAGR) of 8 percent throughout the forecast period to reach $2 billion in 2016. The market value of advanced disinfection systems, lead by chloramines, is estimated at $478.5 million in 2011 and is growing at a compound annual growth rate (CAGR) of 8.9 percent to reach $734 million in 2016.

According to the United Nations” Third World Water Development Report (2009), up to $148 billion will need to be invested worldwide in water supplies and wastewater services annually to 2025. That figure reflects chronic underinvestment in water infrastructure. This problem is manifest not only in the developing world, but also in advanced economies, which will need to make considerable investments in the coming years just to maintain services, according to CompaniesAndMarkets.com.
CompaniesAndMarkets.com says the majority of expenditures for water treatment are for conventional water equipment and chemicals; however, an ever growing percentage relates to advanced treatment technologies, including membrane filtration, ultraviolet irradiation, ozone disinfection, and some novel disinfectant systems.

This report examines the market for four categories of advanced municipal water treatment: membrane filtration, ultraviolet irradiation, ozone disinfection, and some novel advanced oxidation processes. Five-year projections are provided for market activity and value. Industry structure, technological trends, pricing considerations, R&D, government regulations, company profiles, and competitive technologies are included in the study.
