Digital Thirst: Batam's Data Centres and the Looming Water Crisis

The cries of "Water! Water!" echoing through Batam, Indonesia, are not a plea for rain, but a raw testament to a direct conflict: the island’s residents battling drying taps while vast data centres churn through resources. Approximately 300 residents from areas like Bakau Serip stormed a data centre compound in Nongsa Digital Park, armed with empty bottles and jerry cans, furious that their water supply had ceased for three months. This isn't merely an inconvenience; it's a stark illustration of escalating resource competition in the pursuit of digital economic transformation.

Dewi Susanti, a protester, highlighted the dire situation, stating their village's taps had been consistently dry since the data centres' arrival, forcing reliance on tanker trucks dispensing "dirty, cloudy and smelly" water. While Batam's water utility aims to improve supply, it remained silent on a direct link to data centre demand. BP Batam, the agency overseeing trade and industry, attributed the shortages to a prolonged dry spell, denying allegations of water diversion to the digital infrastructure. Yet, locals increasingly voice concerns about competing with servers for fundamental resources.

This isn't an isolated incident. The island, striving to become a digital hub, has witnessed similar protests in August and September. These public outcries compelled authorities to mandate that new data centre firms in Batam must construct their own desalination plants, shifting away from reliance on existing freshwater reservoirs. This policy pivot underscores the direct impact of citizen activism on industrial development frameworks, forcing enterprises to internalize infrastructure costs previously externalized onto the public water supply.

One of the critical challenges identified by Agus Hasan, a professor at the Norwegian University of Science and Technology, is the scarcity of reliable data on data centre water use in Indonesia, often treated as proprietary information by companies. This lack of transparency fuels public distrust and legitimate grievances. "We should build [data centres] rationally, transparently, and responsibly, and insist on seeing the numbers... [Otherwise] those kept in the dark while their taps run dry will push back, and rightly so," Hasan cautions, pointing to the inevitable backlash when basic needs are perceived to be compromised for corporate gain.

The friction in Batam is a microcosm of a broader global phenomenon. A growing backlash against data centres is evident across the US, the UK, and parts of Asia, as tech giants pour billions into AI infrastructure. Beyond the constant hum of machines and security lights, communities worldwide are increasingly concerned about the immense pressure these windowless structures place on vital water and energy resources. Engineers deploy elaborate cooling systems to prevent servers from overheating, a process that consumes significant amounts of water.

Research from the US illustrates this scale: a typical data centre can consume approximately 300,000 gallons of water daily, equivalent to the daily usage of about 1,000 US households. A larger 50MW facility could demand as much water as 2,200 households and enough electricity for 22,000 homes per day, according to Malaysia's central bank. While specific figures for Batam remain undisclosed, the island's chronic water shortages, exacerbated this year, frame the narrative: the cost of digital ambition cannot solely be borne by the populace through the deprivation of essential services. Transparency and accountable resource management are no longer optional but imperative for any nation aspiring to be a 'digital hub' without sparking an internal resource war.
