Thailand water utilities sector revenue (2020-2024)
~THB 100B+ (2024)
Thailand's combined water-utilities sector (municipal supply, industrial water, wastewater treatment) generates roughly THB 100-110 billion in annual revenue per Metropolitan Waterworks Authority (MWA), Provincial Waterworks Authority (PWA), and the SET-listed concessionaires (TTW, Eastern Water Resources Development and Management — EASTW, Bangkok Expressway and Metro — BEM water division). MWA and PWA together generate roughly THB 50-55B of state-enterprise revenue; private concessionaires and industrial water suppliers (TTW, EASTW, WHA Utilities) add another THB 45-50B. The sector profile is regulated and largely defensive, with tariff resets tied to CPI and infrastructure investment cycles.
