Cape Town, South Africa’s 2nds largest city of 4 million people is struggling with lack of water. Day Zero was to be the day the water was turned off if people couldn’t stick to a daily limit of 50-litres. They would have to queue at standpipes. That day has arrived and the taps are still flowing. The city leaders say water-saving efforts mean Day Zero is now pushed back to August the 27th. South African Environmental advisor Dr Anthony Turton joins us once more with the latest.
