The South African city of Cape Town is instructing people to severely restrict water use because of the area’s worst drought in more than a century. The city, a major international tourist destination, said it is experiencing the impact of climate change and predicts little rain in the next three weeks.
It wants daily water usage to be reduced to 100 litres (26 gallons) per person and recommends taking two-minute showers and flushing the toilet only when necessary. Residents worried about sediment from dams with low water levels are starting to boil tap water, said Justin Friedman, founder of For Love of Water , a non-profit group that promotes conservation.
Some people are worried that the city might turn off the taps at some point, he added. The city of nearly four million people is in its low tourist season. Tour operators hope eventual rains will improve the situation before the high season towards the end of the year.
Drought-stricken Western Cape, which includes Cape Town, was declared a disaster zone on Monday by provincial premier Helen Zille. The designation gives more power to authorities to direct resources to the water crisis.
The levels of dams that supply Cape Town are at 20.7%, down by 0.7 points from a week ago, the city said.
It noted that the last 10% of a dam’s water is mostly unusable because of mud, weeds and debris. Municipal repair crews are also struggling to attend to hundreds of leaks and faults that cause water loss.
As dam levels drop, the city said in a statement, authorities will “start to implement a lifeline supply which entails reducing the water pressure to a very low level across” the region.
