The island where locals say data centres are taking their water

BBC (opens in a new tab) · Fact-check by @factdesk

Residents on Batam say the taps ran dry while data centres at Nongsa Digital Park kept water for their machines.

It's unclear how much water or electricity the data centres in Batam are consuming.

These water figures are comparisons, not Batam measurements

The BBC attributes both comparisons, and the next sentence says it is unclear how much water or electricity the Batam centres use. The 300,000-gallon figure restates an Environmental and Energy Study Institute estimate that a medium-sized US data centre can use up to about 110 million gallons a year, roughly the annual use of 1,000 households. That is a ceiling for one size class, not a measurement of a typical centre or of Batam. The 50MW comparison is Bank Negara Malaysia's illustration: about 22,000 households of electricity and 2,200 of water per day, using assumed household use and a water-usage effectiveness of 2.2. It is not a meter reading from the island.

A medium-sized data center can consume up to roughly 110 million gallons of water per year for cooling purposes, equivalent to the annual water usage of approximately 1,000 households.

For instance, a 50MW data centre would consume approximately the equivalent power and water usage for ~22,000 and ~2,200 households per day, respectively.

A typical data centre uses 300,000 gallons a day, so Batam’s centres are taking the island’s water.
