Data Centres' Use of Fresh Water Supply

Ms Elysa Chen asked the Minister for Sustainability and the Environment (a) what percentage of our freshwater supply was used by data centres in the past year; and (b) where such figures are unavailable, whether the Ministry can provide the latest estimates in (i) absolute volume and (ii) proportion to the national freshwater supply.

Most of the water supplied to data centres is met through the supply of NEWater instead of freshwater sources.
