Market Overview
The South Korea Study of Data Center Water Consumption Market focuses on the demand, usage, trends, and sustainability considerations related to water consumption within data centers across South Korea. This includes water used for cooling (chilled water systems, evaporative cooling, air handling units), humidification, and ancillary processes. The study covers all data center types—hyperscale facilities, enterprise-owned campus centers, colocation providers, and edge facilities. Growth is driven by exponential demand for computing power, digital services, AI acceleration, cloud adoption, and local industry reliance on low-latency infrastructure. Meanwhile, concerns around water scarcity, environmental regulation, and corporate ESG commitments are directing attention to water usage efficiency, closed-loop systems, and alternative cooling methods.

Meaning
This study examines how much water data centers consume, how it is sourced, how it is managed, and how efficiency and sustainability opportunities can be introduced. Water is critical to maintaining optimal equipment temperature to ensure reliability and performance. However, reliance on water-intensive cooling methods raises concerns in regions like South Korea, where water resources are finite and subject to seasonal stress. The study evaluates consumption patterns, benchmarking across facility types, identifying risks, and mapping opportunities for reducing usage via reuse, alternative cooling, smart metering, and regulatory alignment.

Executive Summary
The South Korea data center water consumption study reveals that emerging hyperscale and enterprise data centers collectively consume tens of millions of cubic meters of water annually, with per-megawatt usage varying based on cooling design—open-loop evaporative systems consuming significantly more than closed-loop chillers or air-cooled setups. As of 2024, water use intensity (WUI) benchmarks span roughly from X to Y liters/MWh of IT load, depending on cooling architecture and climate adaptation. Growth in AI, high-density compute, and 5G edge facilities is expected to elevate total water use by 3–5% annually through 2030 unless efficiency interventions are adopted. Positive trends include trials of air-cooled and hybrid cooling platforms, site-level water metering, and water performance KPIs embedded in data center design. Challenges revolve around regulatory oversight, infrastructure strain, and operational cost increases, while opportunities lie in closed-loop reuse, alternative coolant systems, and alignment with national water security strategy.

Key Market Insights
One pivotal insight is that newer data centers built with hybrid or air-based cooling show up to 40–60% lower WUI compared to traditional evaporative cooling plants—especially critical during drier months or drought warnings. Integrated water monitoring systems (real-time metering, alerts) are becoming standard, enabling operators to target inefficiencies and leak detection. Another insight is that corporate and hyperscale players are beginning to include water consumption disclosures in ESG reporting, creating a performance and reputational incentive. Location matters: centers in water-stressed provinces (e.g., Gyeonggi, Chungcheong) are piloting reuse schemes or sourcing reclaimed water from municipal systems. Finally, demand from edge or small-scale data centers highlights the need for modular, low-water, or air-cooled designs due to reduced economies of cooling scale.

Market Drivers

1. Rapid data center expansion, especially for AI, cloud, and 5G edge nodes, raising aggregate water demand.

4. Real-time water analytics and KPI dashboards for operators to benchmark and manage consumption actively.

5. Alignment with municipal water reuse and stormwater integration, enabling data centers to tap into sustainable sources.

Market Dynamics
Design and operational frameworks are shifting from prioritizing initial capital efficiency toward lifecycle water-cost optimization. Industry groups and hyperscale operators influence standards, while government bodies engage through sustainability forums and infrastructure planning. Purchase decisions increasingly consider total cost of ownership (capex + water-related opex). Partnerships between data center developers, utilities, and water technology firms are forming to pilot reuse loops and alternative sourcing. Deliverables now include metering contracts and water-reduction guarantees. Awareness of water constraints—especially during seasonal dry periods—is influencing site selection and cooling architecture choices.
