Asia Pacific Desalination Technology Trends

Introduction

Asia Pacific’s coastal cities are facing growing water stress, driven by erratic rainfall, salinity intrusion, and overdrawn groundwater. To meet this challenge, several countries are scaling up desalination capacity—not just for emergency backup, but as a permanent water source.

India, Australia, Vietnam, Indonesia, and Pacific island nations are investing in reverse osmosis (RO)–based systems and hybrid solar-powered units. Modular designs, containerized deployments, and public-private partnership models are expanding access in both urban and remote zones.

Desalination Is Now a Core Strategy for Coastal Cities in APAC

The Asia Pacific desalination market is projected to grow at a CAGR of 10.8% from 2026 to 2035. In India, large RO plants have been deployed in Chennai, Jamnagar, and Tuticorin, while Australia’s coastal cities have integrated desalination into their long-term water planning.

Containerized systems are growing at 9% CAGR, providing scalable solutions for islands, military zones, industrial units, and disaster response. Power optimization technologies like energy recovery turbines and solar-RO hybrids are reducing long-term OPEX.

Public-private models such as BOOT and DBO contracts are now common, particularly in India and Southeast Asia. Major suppliers include IDE, Veolia, Toray, and SUEZ, along with regional integrators.
