Drought in China dried up parts of the Yangtze river last year - but the largest water transfer apparatus ever built still drew from it to supply Beijing's needs.

More than a billion cubic meters flowed through the colossal South-to-North Water Diversion Project in 2022. It traveled from a reservoir in central China to millions of households in the capital 1,200 kilometers away. The journey, via underground tunnels and canals that cross the Yellow River, roughly equaled the distance between Amsterdam and Rome.
