Canadian artist Serge Belo has created what he says is the world's largest water mosaic, to raise awareness about the shortage of clean water globally.

The result is a mosaic spanning 334 sq m, using 15,000 litres of coloured rainwater.

He used 66,000 cups of water to simulate the impurities found in water all over the planet.
