Thailand water demand: municipal vs industrial split
Municipal ~70%
Thailand's piped-water demand splits roughly 70% municipal (MWA, PWA distribution to households and commercial premises) and 30% industrial (raw and treated water to industrial estates, manufacturing plants, power stations), per BOI and Hydro-Informatics Institute (HII) sector tracking. The split has been broadly stable through 2020-2024, with EEC industrial expansion gradually tilting the mix toward industrial as Rayong/Chonburi/Chachoengsao manufacturing scale. EASTW and WHAUP dominate the industrial water layer; municipal supply is overwhelmingly state-utility (MWA, PWA) plus their private concessions.

What not to do with it
Approximate share of piped-water demand by end-use. Excludes agricultural irrigation (RID-managed canal system), which is volumetrically larger but supplied free or near-free.
