The document summarizes Cape Town, South Africa's experience with a severe drought from 2015-2017 that brought the city close to "Day Zero," when water supplies would have been shut off. It discusses how water demand was reduced by 55% through conservation efforts to avoid Day Zero. The city has developed a long-term water strategy through 2040 to build resilience against droughts and transition to sustainable water use, including commitments around access, conservation, developing diverse water sources, and establishing a new relationship with water. The strategy will take 10 years to become water resilient and 20 years to transition Cape Town to a water sensitive city.

- 2. In 2018, the city approached Day Zero, the day when water would have to be shut off. We were experiencing the worst drought on record, and at the height of this crisis, dams were down to just 9.8% of their usable storage capacity. We narrowly avoided Day Zero, but to reduce the risk of this occurring, we have to face the reality of less predictable rainfall patterns. 9.8% usablecapacity One-in-590 year drought (2015 – 2017) DAY ZERO
