The Thailand Federation of Thai Industries (FTI) has issued a stark warning: the nation's booming data centre sector could intensify existing water shortages, placing communities and agriculture in direct competition with a tech industry already worth over 320 billion baht in initial investments. With more than 70 data centre projects either planned or under construction—primarily concentrated in the Eastern Economic Corridor (EEC)—the clash between digital expansion and resource constraints has become one of 2026's most pressing infrastructure debates.
Why This Matters:
• Water consumption from data centres is expected to hit 11.28 billion liters in 2026, climbing to 15.62 billion liters by 2030.
• A single hyperscale facility can use up to 1.5 million liters daily, equivalent to the water needs of 15,000 people.
• Thailand faces a dual water crisis in 2026 due to predicted El Niño conditions, which could bring severe drought and erratic rainfall across non-irrigated regions.
• The Thai Cabinet has approved a new oversight committee to regulate data centre operations, introduce zoning, and enforce sustainability standards for new projects.
The Scale of Thailand's Data Centre Boom
Thailand's data centre industry is on track to expand by nearly 14 times between 2023 and 2028, fueled by surging global demand for artificial intelligence infrastructure and cloud computing. By April 2026, 40 data centres were operational nationwide, with 20 under active construction and 10 in the planning phase. The Thailand Board of Investment (BOI) has greenlit 46 data centre and cloud service projects valued at nearly 168 billion baht, while first-quarter applications alone exceeded 1 trillion baht.
Amazon, Google, TikTok, and Microsoft are among the multinational tech giants funneling billions into facilities clustered in Chonburi and Rayong provinces, where industrial infrastructure is already well-established. Yet the concentration of projects in the EEC—a region already serving as Thailand's manufacturing heartland—has raised alarm bells among conservationists, farmers, and local officials who fear the industrial corridor is nearing its ecological limits.
Water Demand Collides with Climate Reality
Data centres rely on enormous volumes of water to cool servers that generate intense heat, particularly as AI workloads push electricity and thermal outputs to unprecedented levels. One planned hyperscale facility alone is projected to consume 3.3 million cubic meters of water annually, roughly equivalent to the total usage of 37,000 residents. With water consumption across Thailand's data centre sector estimated to reach 10.68 billion liters in 2025 and 15.62 billion liters by 2030, the industry's footprint is expanding faster than water infrastructure can adapt.
The timing could not be worse. The Thai Meteorological Department has forecast an El Niño event stretching from May through July, with predictions of above-normal temperatures and below-normal rainfall throughout 2026. Climate experts warn that the phenomenon could intensify into a "super El Niño" by October, bringing severe drought, extreme heat, and unpredictable storm patterns that may trigger flash floods in some areas while parching others. Reservoir levels in Chonburi have already begun declining, and farmers in the EEC fear that further industrial water allocations will leave them without sufficient supplies for irrigation and daily needs.
Adding to the complexity, some data centre investors have signed overlapping water reservation agreements, a practice that has made accurate resource planning nearly impossible for government agencies tasked with balancing competing demands.
Pollution Concerns and Ecosystem Threats
Beyond sheer volume, water pollution is emerging as a parallel concern. Cooling systems in data centres often circulate water mixed with chemical additives, and the discharge of wastewater—if inadequately treated—can harm rivers, fisheries, and local ecosystems. Fishers in coastal provinces have voiced fears that runoff from industrial facilities could contaminate breeding grounds and reduce catch yields, compounding economic pressure on communities already grappling with irregular weather patterns.
Environmental groups have also criticized the lack of transparency surrounding environmental impact assessments for some data centre projects, arguing that approvals have been fast-tracked without sufficient public consultation or ecological review.
Government Moves to Impose Regulatory Framework
In response to mounting pressure, the Thai government is drafting a comprehensive regulatory framework to manage the sector's impact on national resources. A new committee, chaired by a deputy prime minister and including ministers from the Digital Economy and Society, Interior, and Energy portfolios, has been approved by the Cabinet to oversee approvals, monitor water and power consumption, and assess environmental risks.
The regulations will apply differently depending on project status. Existing operators will undergo audits focused on water use, while facilities under construction will face additional requirements to reduce potential impacts. New projects will be subject to the most stringent rules, including mandatory sustainability criteria such as power usage effectiveness (PUE) standards, renewable energy integration, water recycling mandates, and waste heat recovery systems.
The government is also exploring zoning measures to shift future data centre development away from the EEC to regions with more robust water infrastructure. Areas such as Lampang province, near the Mae Moh mine, have been floated as potential hubs, offering proximity to energy resources and less competition for water supplies. The Office of the National Water Resources (ONWR) is developing a master plan for water resource management across 22 river basins, including the EEC, with completion targeted for 2027.
What This Means for Residents
For those living in Chonburi, Rayong, and surrounding EEC provinces, the data centre boom represents both opportunity and risk. While the industry promises job creation, foreign investment, and tax revenue, residents may face increased water tariffs, periodic shortages, and stricter usage quotas as authorities attempt to balance industrial demand with household and agricultural needs.
Farmers should prepare for potential irrigation restrictions during the El Niño period, particularly in non-irrigated zones. Local governments may prioritize water allocation for domestic consumption, but prolonged drought could strain even those reserves. Community groups and agricultural cooperatives are urged to engage with provincial water management committees to ensure their voices are heard in resource allocation decisions.
For investors and businesses, the new regulatory environment will likely mean longer approval timelines, higher compliance costs, and mandatory sustainability reporting. Companies planning data centre investments should budget for advanced cooling technologies, recycled water systems, and renewable energy integration to meet forthcoming standards.
Industry Shifts Toward Greener Models
Some operators are already pivoting toward sustainable practices. Amazon Web Services (AWS) has pledged to expand its use of recycled water in data centres globally, a model that could be adapted for its Thailand operations. The Asian Development Bank (ADB) has provided a green loan to GSA Data Center 01 Company Limited to fund a highly energy-efficient facility in Samut Prakan province, targeting LEED Gold certification and a low PUE rating.
Other firms, such as Etix Everywhere, have deployed solar panels on their Bangkok data centre, aiming for 100% renewable electricity sourcing by 2025. Planet Communications Asia (PlanetComm) has integrated smart cooling systems to reduce carbon emissions and improve energy efficiency.
Conservationists are advocating for the widespread adoption of the "6Rs"—reduce, reuse, recycle, rethink, redesign, and regulation—as a framework for managing water demand. Circular water solutions, including closed-loop cooling systems, can achieve freshwater savings of 50% to 70% compared to conventional methods. Rainwater harvesting and wastewater reclamation are also gaining traction, with regional peers in Malaysia, Singapore, and the Philippines already implementing similar strategies.
Regional Context and Competitive Pressure
Thailand is not alone in grappling with the tension between digital infrastructure growth and environmental limits. Malaysia has introduced a Data Centre Standards and Certification framework, while Singapore's Sustainable Tropical Data Centre Testbed is developing cooling solutions designed to cut energy and water consumption by up to 40%. In Johor, Malaysia, authorities have halted new water-intensive data centre projects pending infrastructure upgrades.
The ASEAN Guide for Sustainable Data Centre Development provides a regional blueprint emphasizing metrics like Water Usage Effectiveness (WUE) and climate resilience. Thailand's regulatory reforms align with this broader Southeast Asian push to balance economic competitiveness with ecological sustainability.
As the government finalizes its oversight mechanisms and industry players adjust to stricter standards, the next 18 months will determine whether Thailand can sustain its position as a regional data hub without sacrificing the water security of its residents and farmers. The stakes are high—not just for the tech sector, but for the millions who depend on the same rivers, reservoirs, and aquifers that now fuel the cloud.
