Data centres consume water directly to prevent information technology equipment from overheating. They also consume water indirectly from coal-powered electricity generation.

The team projected that by the end of the decade, China would have more than 11 million data centre racks, which house servers, cables and other equipment. That is nearly triple the number it had in 2020 of around 4 million.
It pointed to a preprint study – meaning it has not yet been peer-reviewed – from last year by researchers in the United States that showed the large language model GPT-3 consumed 500 millilitres (16.9 fluid ounces) of water for every 10 to 50 responses it generates. That is 20 times more than it takes to produce 50 Google searches.

The report said that if 100 million users had a conversation with ChatGPT, the chatbot “would consume 50,000 cubic metres of water – the same as 20 Olympic-sized swimming pools – whereas the equivalent in Google searches would only consume one swimming pool”.
CT Low, co-author of the report and geospatial risk lead at China Water Risk, said the accelerated development of generative AI would add pressure to the country’s already stressed water resources.
Lead author Debra Tan, director and head of China Water Risk, said improving energy and water efficiency with existing technology were simple solutions to address water risks.
“For the ICT sector, the time to tackle water risks is now – we must get on top of these before the explosion of AI,” Tan said.
She said China’s ICT giants are encouraged to become “water neutral” or “water positive” – goals their counterparts in Silicon Valley such as Meta and Google are also pursuing.
A water neutral company is one that offsets its water footprint, while a water positive one replenishes more than its water footprint, ideally after reducing water use as much as possible, according to the report.
Strategies to minimise and offset water use include watershed restoration, improving water efficiency in existing facilities, reusing waste water and collecting rainwater.
Tan added that the Chinese government was taking steps to manage rivers holistically, “from source to sea”, and could be expected to adopt tighter regulations and water usage effectiveness standards for the ICT sector.
