Ensuring water supply has become a pressing challenge for Indonesia’s rapidly growing data center sector. Key hubs such as Jakarta and Batam Island in the Riau Islands are located in hot and humid climates, where operators rely heavily on conventional mechanical cooling systems—driving up water consumption.
Experts warn that limited disclosure of water usage data is hindering effective oversight, calling on the government to tighten regulations and require regular reporting of water efficiency.
Unlock the full article to explore three key takeaways:
- Hyperscale data centers consume 1–5 million liters of water daily; Indonesia's climate makes cooling far more water-intensive.
- Most legacy facilities rely on water-cooled towers; some operators use air-cooled chillers and rainwater recycling.
- Researchers call for water assessments in permitting and mandate public disclosure of water efficiency metrics.
