Our groundwater expert Jan Kürstein explains how cities can learn from Cape Town that was dramatically close to a ‘Day Zero’ shutdown of the public water utility in 2018.
Avoiding Day Zero in Cape Town
Responsible use of natural resources 21 March 2022 Jan Kürstein
South Africa’s water supply depends largely on surface water, raising the risk of low water supplies after periods of drought. Ramboll aims to show how Danish approaches to managing ground water can help ensure a more sustainable water supply.
Responsible use of natural resources
Making the most of our natural resources and protecting them for future generations
This year, for UN World Water Day, we celebrate groundwater. Modern life as we know it would simply not be possible without this precious resource. It’s worth reminding ourselves about the importance of managing groundwater in the most sustainable way possible.
In California, groundwater is a critical source for farms and communities, and on average groundwater provide 40% of their water supply. Due to climate changes, California suffers from an increasing number of droughts, leaving the Californian communities even more dependent on groundwater.
Areas like California experience longer and more severe droughts due to climate change. To avoid water scarcity, they need to increase the share of groundwater in the water supply. Geophysicists from Ramboll help map groundwater resources around the world by using advanced scanning technology. Listen to Ramboll’s podcast about ideas that help solve global problems.
