2/1/18 - 50 Liter/Day Water Limit For Cape Town Kicks In; 4/12 - Municipal Water System Shuts Off

El Nino has since moved on and the La Nina months are here. But the blistering drought remains. Stuck in a self reinforcing cycle of heat and lack of rainfall. After such a long period of such abnormal punishment, the reservoirs that feed Cape Town are on the brink of running out.

With supplies dwindling, residents of this major city and tourist destination have been slapped with serious water restrictions. Each has been asked to use just 87 liters of water per day. That’s about 1/4 the average use for an American. One that provides precious little for washing dishes, taking showers, flushing the toilet, doing the laundry, preparing food, and drinking. But only about half of Cape Town’s residents are complying with the restriction.

In the Cape Town region, crushing drought continues unabated. And as a result of the combined lack of compliance with rationing and lack of rain, the reservoirs are swiftly falling. By February 1, Cape Town will ask residents to adhere to a draconian 50 liter water restriction. And if that doesn’t work, if the rains don’t somehow miraculously come, then Cape Town will effectively run out of enough water to fill pipes. Under this very difficult scenario, water pipes to everything but essential services like hospitals would be cut off. Residents would be forced to make daily treks to one of 200 outlet pipes to fill up water bottles. If this happens, then Cape Town will be the first major city in the world to be forced to fully cut off its municipal water supply.

The day on which this historic and ominous presage of climate change related water difficulties is predicted to happen is a moving target. And lately the target has been moving closer. Ignominiously called Day Zero, the water cut-off date for Cape Town as of last week was April 21 of 2018. This week, due to failure to adhere to water restrictions and due to unrelenting drought, that date has jumped to April 12.
