The situation is dire. Cape Town’s more than 4m residents have been told to cut their daily limits from 87 litres to 50 litres per person.

That’s the equivalent of a six-minute shower with a low-flow showerhead in a city where they already line up with containers at outdoor springs, leave toilets unflushed — and where the province’s top local politician calls unwashed hair a status symbol.

Should the water stop, Cape Town — ironically first settled permanently by the Dutch in 1652 because it was considered climatically ideal for a supply station to underpin the south-east Asian trade of their fleet — will become the world’s first major city in which the taps literally run dry.

There is no precedent to draw upon, but it is clear that this would have an enormous impact in a politically

volatile and economically straitened country.

The shortage is the result of a three-year drought that emptied the city’s dams. But the manner in which this

potentially disastrous state has been reached has sobering lessons for an international political order in which catastrophic climatic events are more frequent and long-term planning less so.

Government officials, scientists, and politicians, especially in the more arid southern hemisphere, are watching

intently, aware that one of their own major cities might be next.

It is a measure of the levels of anxiety, as well as a lack of confidence in the capacity of state structures to cope, that even the politicians seem to be relying on a miracle.

Last November, a popular cowboy-hatted lay preacher, Angus Buchan, was invited to lead a pray-for-rain gathering in this nominally secular country’s parliament.

Buchan, who arrived fresh, he claimed, from raising a woman from the dead, reassured his anxious congregants that the dams would be full by March.

Whatever the timing, it promises to be a cliffhanger.

Cape Town’s winter rainy season runs from May to August. Experts initially calculated ‘Day Zero’, the date upon which there is insufficient water in the Western Cape Water Supply System to push through the pipes to the suburbs and sprawling informal settlements that encircle the city, to be around April 16.

It has since been pushed back to mid-May. With domestic consumption accounting for the bulk of water usage, officials are hoping their latest desperate cuts can stave off Day Zero until the rains begin.

Agriculture, especially the wine estates that along with the scenic splendour of the region are a major draw for the 1.5m foreigners who visited the city last year, uses about a third of the water.

Irrigation usage has declined over the past five years, although there have been criticisms of the Department of Water and Sanitation for not cutting the agricultural allocation when the prospects of an extended drought became more apparent. Instead, they increased it.

It is this kind of blundering that lies at the nub of the unfolding natural disaster. For Day Zero is not primarily driven by climatic change, although climatologists agree that phenomenon plays an as yet scientifically undetermined role.

“Simply blaming climate change is a cop-out,” says Graham Jewitt, the Umgeni Water Chair of Water Resources Management at the University of KwaZulu-Natal and director of its Centre for Water Resources Research. “It has become just another scapegoat for the blame game of the politicians.”

The core problem is that the city of Cape Town and its home province, the Western Cape, are governed by the

liberal Democratic Alliance.

That makes the Western Cape the only provincial government not run by the ruling African National Congress (ANC), which has dominated national politics since winning the country’s first post-apartheid elections in 1994.

Despite almost 25 years in power, the party of Nelson Mandela is still struggling to make the transition from being a liberation organisation steeped in Marxist-Leninist notions of being the sole authentic voice of the people — the widely despised president, Jacob Zuma, often boasts the ANC will rule until “Jesus comes back” — to being just

another political contender in a modern democracy.

Internationally, this translates into a stifling lack of pragmatism. The South African government, which is strongly aligned with the Palestinian cause, has snubbed informal offers of help made by the Israeli ambassador, according to the South African Jewish Report.

Israel has substantial expertise in desalination technology, but last year the mere presence of a former Israeli ambassador on a panel to discuss water management aroused such protest that the event was cancelled.

Many ANC politicians would love to see the liberal ruling Democratic Alliance tarnished by failure in the Cape, perhaps opening the way to the ANC recapturing the province in 2019.

Accusations and insults have been flowing thick and fast between the local, provincial, and national tiers of government, each with its own legislatively determined role in the water procurement process.

Water and Sanitation has blamed the other two for not reacting vigorously enough when it became apparent, years ago, that densification — the city’s population has increased by 50% in the past decade — was going to strain water supplies.

They, in turn, have accused the national government of dragging its feet on capital funding for infrastructure and maintenance, as well as withholding emergency disaster relief funds.

While it is true that all the parties have made blunders, city officials probably shouldn’t be blamed for lack of long-term planning. Cape dams were overflowing as recently as 2014; the statistical chance of a three-year drought was said to be 0.1%.

Given those odds, local authorities did not want to take the political risk of diverting funds sorely needed for social development.

But happen the drought did, and it has exposed the operational dysfunction in the national ministry. Just six weeks ago, Water and Sanitation released its draft national water masterplan for comment.

Driven by what it calls a “sense of urgency”, it admits that “the current water crisis serves as a stark reminder of the impact of delayed action” in the augmentation of the Western Cape Water Supply.

Belated attempts are now being made to bring aquifer water to the surface, as well as an emergency desalination plant. In the long term, most crucially, residents have to get used to using water more sparingly, says Jewitt.

The immediate catastrophe of Day Zero can still be averted. With the direct intervention last week of Zuma’s likely successor, deputy president Cyril Ramaphosa, and Western Cape prime minister Helen Zille, the muddled responses of competing bureaucracies are at last being pulled together.

At the most basic level, cutting consumption to the 50-litre maximum could move Day Zero along the calendar into the traditional rainy season.

Of course, whether precipitation then actually materialises remains in the lap of the gods.
