The politics of the dry tap by Solomon Mensah

Johannesburg has discovered an unusually effective way of turning water into a political weapon, stop delivering it. For a city accustomed to the grand language of African urban ambition, the indignity is almost comically basic. The skyscrapers remain. The shopping centres glitter. The highways crawl with expensive cars. Yet behind the gates and apartment doors, residents are increasingly learning to regard the household tap with the suspicion normally reserved for a politician's promise.

More than a third of Johannesburg's water supply is reportedly disappearing through leaks and bursts, an astonishing 655m litres a day. That is not merely an engineering problem. It is a civic insult. Water is one of those services whose importance becomes apparent precisely when government fails to provide it. Electricity can be replaced, briefly, with batteries and solar panels. A rubbish collection can be postponed. Water cannot be negotiated with.

The political consequences are therefore predictable. South Africans have become veterans of infrastructure failure. Power cuts taught households to buy inverters. Now water shortages are teaching them to buy tanks, filters and boreholes. The wealthy are constructing private versions of the public utility they have stopped trusting.

This is perhaps the most dangerous feature of Johannesburg's crisis. The rich are not merely suffering less from municipal failure; they are acquiring the means to escape it. Once a household has its own borehole, storage tanks and filtration system, the condition of the municipal network becomes an abstraction. The city may be collapsing next door, but the swimming pool remains full.

That creates a vicious economic circle. Those most capable of withdrawing from the public system have the strongest incentive to do so. Those left behind are poorer residents who cannot drill their way out of a crisis. The public utility consequently becomes more concentrated among people with fewer resources, while its political and financial foundations weaken.

It is difficult to imagine a better recipe for inequality. The Johannesburg water crisis should therefore not be understood simply as a drought story, nor as another chapter in the familiar catalogue of South African infrastructure woes. It is a story about the slow privatisation of citizenship. The affluent citizen becomes a customer of private solutions; the poor citizen remains a captive of public failure.

That distinction matters electorally. Local elections are usually fought over potholes, refuse collection, housing and electricity. Water is different. A pothole damages a car. A dry tap reorganises an entire household's day. Children cannot wash. Toilets become unusable. Cooking becomes complicated. Elderly people and vulnerable residents must depend on tankers or neighbours. The inconvenience becomes intimate.

And intimacy is what turns administrative incompetence into political anger. The governing African National Congress has particular reason to worry. Its long dominance has increasingly been tested by voters who no longer regard liberation credentials as an adequate substitute for competent municipal government. Johannesburg's water failures offer opposition parties a brutally simple argument: forget ideology; look at the tap.

Yet blaming politicians alone would be too comfortable. Johannesburg inherited old pipes, rising demand, urban expansion and enormous maintenance requirements. Climate change adds another layer of difficulty. But these facts explain the problem; they do not excuse the failure to anticipate it. Infrastructure does not collapse overnight. Pipes spend decades announcing their age.

Maintenance is politically dull because successful maintenance produces nothing photogenic. There is no ribbon-cutting ceremony for a pipe that does not burst. Politicians naturally prefer visible projects. Voters, however, eventually become interested in the invisible ones when the visible city can no longer function.

Johannesburg is approaching that moment. The great irony is that the city's wealth, which should make reliable water easier to provide, may instead make collective failure easier to tolerate, for some. Private boreholes, tanks and filtration systems can conceal a public crisis long enough for it to become permanent.

That is the real warning from the dry tap. A city does not need to run completely out of water to experience a Day Zero. It merely needs enough citizens to stop believing that the
