"There's no need to panic. We just all need to be prudent," she said. "I implore you all to use water sparingly." South Africa's government says the country is one of the world's 30 driest nations. The city of Cape Town last year faced the prospect of "Day Zero," or the date when most taps would have to be cut off because of a long drought. Strict water rationing in the city of 4 million people managed to avert that disaster.
Now the country's commercial hub, Johannesburg, and the capital, Pretoria, are among parts of the country most at risk. The Vaal Dam that supplies the province encompassing both cities has dropped below 50% capacity, authorities say.
In a speech earlier this year, Sisulu laid out the stark problems that South Africa faces as its water needs grow. More than 60% of the country's water supplies go to agriculture, leaving only 27% for personal use, she said.
Aging water infrastructure and "huge financial mismanagement" pose a challenge. At least one-third of the country's 144 municipalities are considered by dysfunctional by water authorities, Sisulu said: "Our water management is poor."
In 1994, after the end of South Africa's harsh racial segregation known as apartheid, the new government saw widespread inequality in access to water and declared water access to be a basic human right, the minister said, adding that the country has not made much progress since then.
"This is a shameful situation of a right we had declared so long ago," she said.
