The worst drought in 30 years could see thousands of South Africans without water if the rains do not come soon.

The El Niño climate phenomenon has run reservoirs and dams dry, forcing the national government and municipalities to institute stringent restrictions to save the little water the country has left.

But who are the biggest water wasters in the three largest metros?

Johannesburg

Jo’burg phased in water restrictions last year. Households using more than 20 000 litres a month now face penalties.

The biggest household water users live in Waterval in Midrand, where each property laps up 159 000 litres a month, trailed by Witpoort at 111 000 litres and Westcliff, where homes use 96 000 litres a month.
