- Eastern Water Resources Development and Management Public Company Limited (EASTW-R.BK) develops and manages water distribution pipeline systems in Thailand's Eastern Seaboard region, encompassing Chachoengsao, Chonburi, and Rayong provinces; supplies raw water and industrial water to industrial estates, factories, and other consumers; produces and supplies tap water through its subsidiary Universal Utilities 1992 Co., Ltd.; provides operation and maintenance management for waterworks; offers wastewater treatment, waterworks management, and engineering services; delivers waste treatment and reclaimed water services; installs wastewater treatment systems tailored to specific businesses with quality control using modern technology; and rents office buildings. The company operates an extensive 553-kilometer water transmission network, the longest and most integrated in the Eastern Economic Corridor (EEC), linking government-owned reservoirs, rivers, and private reservoirs to serve industrial, governmental, and residential customers across eastern Thailand. Founded in 1992 and headquartered at East Water Building in Bangkok's Chatuchak district, Eastern Water targets primarily the industrial sector, which accounts for a significant portion of its raw water sales, alongside consumer and municipal segments in the EEC and select provincial areas like Nakhon Sawan and Phitsanulok.
In recent developments, the company issued Thailand's first blue bond in August 2025, raising 620 million Thai baht with participation from the International Finance Corporation (IFC) and other investors to maintain and enhance its pipeline infrastructure and support water security initiatives. Through its joint venture Eastwater Stecon Utilities Co., Ltd. (EWS) with Stecon Power Co., Ltd., Eastern Water signed a 10-year industrial water supply agreement in October 2025 with Bridge Data Centres (Thailand) Co., Ltd., a Bain Capital-backed entity, to provide sustainable water for a new hyperscale data center campus in Chonburi's EEC, commencing May 2026 and underscoring expansion into data center utilities. These moves align with capacity expansions, such as prior additions like the Nongkho 2 and Tabma reservoirs, boosting raw water supply potential, and position the company as a key enabler of industrial growth in Thailand's EEC amid rising demand from emerging sectors.
