Patong-Phuket desalination and reuse capacity
~24,000-25,000 m3/day
Thailand's installed seawater-desalination capacity totals roughly 24,000 m3/day per academic and industry compilations, with the Patong (Phuket) BOOT concession standing out: a 25,000 m3/day reverse-osmosis wastewater-reclamation project signed in 2012, completed in 2014. Phuket annually consumes ~70 million m3 of water against ~56 million m3 of natural supply, creating a structural deficit that drives tourism-industry demand for desalination and water reuse. Patong's RO reclamation feeds back into the municipal supply via dedicated pipeline. As climate variability and tourism growth tighten the deficit, additional desalination and reuse capacity is in the EEC and Andaman coast planning pipeline.

What this tells you
Thailand's installed seawater-desalination capacity totals roughly 24,000 m3/day per academic and industry compilations, with the Patong (Phuket) BOOT concession standing out: a 25,000 m3/day reverse-osmosis wastewater-reclamation project signed in 2012, completed in 2014. Phuket annually consumes ~70 million m3 of water against ~56 million m3 of natural supply, creating a structural deficit that drives tourism-industry demand for desalination and water reuse. Patong's RO reclamation feeds back into the municipal supply via dedicated pipeline. As climate variability and tourism growth tighten the deficit, additional desalination and reuse capacity is in the EEC and Andaman coast planning pipeline.
What not to do with it
Patong figure is the largest single RO reuse plant in Thailand. Total Thai desalination capacity small relative to GCC peers; reuse and groundwater dominate the tight-supply playbook.
