—Earlier this year, the South African city of Cape Town was told that it would make history by April 16. On that date, dubbed Day Zero, it was expected to become the world’s first major city to run out of water because of an extended drought. More than 1 million households would face extreme rationing or no water at all as reservoirs went dry.
But then something happened. The date was pushed back to June 4. And this week, Day Zero was set for July 9.
It was not rain that helped delay the threatened cutoff. Rather, the people of Cape Town have cut their water consumption. In fact, over the past three years, water use has fallen by more than half in a collective effort to share a valuable resource. The residents’ regard for each other went up, and with it, the amount of available water.The city still has far to go to adjust its supply and demand of water. Yet its ability so far to manage the crisis might serve as a model for other drought-stricken regions.
In California, for example, the state’s Water Resources Control Board plans to permanently reinstate some watering bans and conservation programs as a result of a new drought. In 2015 and 2016, during the last drought, Californians cut consumption by more than 20 percent. But many people have resumed heavy usage after the drought emergency ended a year ago. The state wants people to think longer-term on their water use.Worldwide, the availability of water is in decline as populations rise and people move to cities. This is forcing a new focus on ingenuity and cooperation to ensure supplies. The physical solutions are obvious: stricter water use standards, more efficient uses, long-haul pipelines, grey water capture, desalination, and other ways to change people’s relationship with water. But the hard part is achieving a change of thinking that brings people together to recognize a common problem that requires shared solutions. A mental flexibility must match the fluidity of water.
