Market Overview and Growth Outlook

The water treatment technology market is likely to reach USD 270 billion by 2028, compared with an estimated USD 176 billion in 2021. Market expansion is occurring as water treatment becomes increasingly important for improving quality and safety across drinking, industrial, irrigation, and environmental-discharge requirements while freshwater scarcity adds pressure to available water supplies.

The water treatment technology market is expected to grow at a CAGR of 4.9% during 2022-2028. Population growth and industrialization are increasing demand for chemically treated water, while shortages of freshwater resources are encouraging governments in developed and emerging economies to concentrate more closely on technologies that can provide clean and usable water.

From a competitive and technology perspective, water treatment technology market share dynamics include an established position for Reverse Osmosis within Membrane System Type. The category held the largest share in 2021, primarily because reverse osmosis technology was widely used in emerging markets such as China and India.
