From AI Factory Construction Begins in Central Java Amid Water Supply Concerns

How could the AI Factory development in Central Java affect Batang?

Possible What happens if… A possibility worth considering, not a forecast.

AI factory's massive water demand may strain Batang's local water supply The construction of the Zankore AI Factory in Batang, Central Java, requires large volumes of water for cooling its servers. The first phase, with a capacity of 200 megawatts, could evaporate between 4.8 and 9.1 million liters of water daily. This demand is significant because the local raw-water infrastructure in the Batang industrial zone has a daily capacity of 24.5 million liters. If the factory relies on this source, its operation could consume more than 30% of the infrastructure’s daily capacity, potentially deepening water insecurity in an area already struggling with drought and land subsidence.

How it reaches Batang

Reported by news outlets

Advanced AI infrastructure generates heat that cooling systems must continuously remove, often by evaporating water through cooling towers. Based on projections, Zankore’s 200-MW first phase could evaporate between 4.8 and 9.1 million liters of water per day.

Why it matters

The development of Zankore represents a massive investment of about US$4.59 billion, positioning Indonesia as a regional AI hub. However, this economic benefit carries a risk of a negative externality, where profits accrue to shareholders while the environmental cost, particularly water consumption, falls on the local community in Batang.

This concern is heightened by the existing environmental fragility of Central Java. The region recently declared a drought alert, affecting 2.34 million people, and the northern coast is already struggling with land subsidence, making water management critical for community survival.

What we don't know yet

Will Zankore use alternative cooling systems, such as seawater-based cooling, to reduce freshwater consumption?
What specific rules will authorities establish for allocating water between industrial users and local communities in Batang?

What would change this answer

Zankore publicly discloses its cooling technology and water sourcesThis would clarify the exact resource demands and allow local authorities to better plan for water allocation and contingency during droughts.

The government establishes clear rules for water allocationThis would mitigate the risk of the AI factory deepening water insecurity for the local population.
