By Feedwater Source

Seawater accounted for a share of 72.4% in 2025, reflecting its extensive availability as a feedwater source for large-scale desalination plants in water-stressed coastal regions. Seawater desalination provides an alternative source where freshwater resources are limited.

Brackish water is projected to undergo growth at a CAGR of 8.0% during the forecast period, as treatment facilities use moderately saline groundwater and other brackish sources to supplement freshwater supplies. Its lower salt concentration than seawater can also reduce treatment requirements in suitable locations.

By Capacity

Large-scale desalination plants led the capacity segment with a share of 51.2% in 2025, supported by their ability to process substantial volumes of water for municipal networks and other large users.

Small-scale desalination is anticipated to record a growth rate of 9.6% during the forecast period, driven by the need for decentralized water treatment in remote communities, islands, and locations with limited infrastructure.

By End Use

By end use, municipal applications accounted for a share of 57.6% in 2025, owing to the use of desalinated water in public water supply systems and urban drinking-water networks.

The industrial applications segment is expected to grow at a CAGR of 9.5% during the forecast period, as manufacturing plants, power facilities, and other industrial operations require reliable water sources for processing and operational use.
