Across South Africa, recent heavy rains have not done much to ease the shortages. The IOL.co.za news portal says that levels at the Vaal Dam, which supplies water to Johannesburg, have risen for the 11th week in a row but the situation is still "dire". In Cape Town, officials say that residents and businesses are still using 7m litres (1.5m gallons) too much each day, and have warned people against waste. Gardeners, have been told they may only use one bucketful of water at a time, and then only on Tuesdays and Saturdays.
