4. Study Fig. 3, which shows a news excerpt on the water crisis in Cape Town. Water Crisis in Cape Town Cape Town’s water crisis got so bad in 2018 that there were competitions to see who could wash their shirts the least. Restaurants and businesses were encouraging people not to flush after going to the toilet. At the most extreme, residents were restricted to a maximum of 50 litres a day – not easy when showers alone can use up to 15 litres a minute. The city was just 90 days away from turning off the taps. However, by changing the city’s habits, Cape Town managed to prevent the worst of the water crisis. The City of Cape Town introduced increasingly strict restrictions where they limited the volumes of water used and also restricted what the water was used for. Filling swimming pools, washing cars, and fountains were all banned. Households using high volumes of water faced big fines. The city also increased tariffs and rolled out water-management devices that set a daily limit on the water supply to properties.
