How to get fresh water in Malta
Down the centuries, the Maltese have developed a clever system of underground tunnels, called galleries, to extract the water for human consumption.
About 97m (320ft) beneath the surface of the island lie the Ta' Kandja galleries. Reached by a lift, the tunnels stretch out for several kilometres like the spokes of a wheel, all half-filled with water that is pumped up to the surface and then to homes and farms around the island.
The water in the tunnels is fresh. But just 10m below, it is salty. And thanks to climate change the brackish water is rising.
