South Africa’s second most populous city, Cape Town, implemented a raft of water use restrictions in early 2018 that enabled it to avoid "day zero"—a complete loss of drinking water.
As a result, the city now is implementing a disaster management plan to avert a possible future day zero if dam levels drop again. The plan includes construction of desalination plants, a groundwater augmentation scheme and a water recycling plant, with a combined daily water supply capacity of 144 million liters.
