Market Overview
The Data Center Water Consumption Market in Malaysia examines how much water is required for cooling, humidification, and operational maintenance in data centers operating across the country. As Malaysia advances its digital transformation strategy with growing demand for cloud services, hyperscale facilities, and edge computing, understanding water use is vital in regions with tropical humidity and growing environmental awareness.

In Malaysia’s equatorial climate, data centers frequently rely on water-intensive cooling technologies such as evaporative cooling towers and chillers. As these facilities proliferate, especially across Cyberjaya, Penang, Johor Bahru, and Sabah’s Kota Kinabalu, the total water draw from municipal and industrial sources becomes significant. Managing water consumption effectively is essential for sustainability, regulatory compliance, and operational resilience in an environment where water scarcity is not widespread, but environmental stewardship and utility management are increasingly emphasized.

Meaning
This study refers to the usage of water in maintaining optimal operating temperatures and environmental conditions in data centers. Key areas include:

• Evaporative Cooling (make-up water for cooling towers)

• Chiller Systems (condensate and maintenance water)

• Humidification Systems (particularly in drier indoor conditions)

• Facility Maintenance (cleaning generators, HVAC coils, etc.)

Understanding and optimizing these water flows is critical, especially as Malaysia embraces renewable energy and moves toward net-zero commitments. Efficient water use ensures long-term economic sustainability and reduces environmental impact.

Executive Summary
Malaysia’s data center footprint is expanding rapidly, with racks and megawatts increasing demand for both energy and water. It is estimated that Malaysian data centers consume several million cubic meters of water annually through cooling-related operations, with volumes expected to grow alongside digital infrastructure expansion by 8–10% per year through 2030.

Unlike arid regions, Malaysia benefits from abundant water but still confronts importance of conservation—particularly in urban areas and during seasonal dry spells. Leading operators are piloting hybrid cooling, rear-door heat exchangers, greywater reuse, and smart monitoring to reduce dependence on freshwater. Regulators and sustainability frameworks are beginning to recognize water as a critical resource in data center certification standards.
