Berlin is a sponge city

In order to minimise the risk of flooding, store rainwater and prevent the formation of heat islands, Berlin is relying on the needs-based planting of areas, roofs and façades as well as the use of AI to make the best possible use of its own water potential. In addition to intelligent rainwater irrigation management, grey water systems are increasingly being used in the private, industrial and commercial sectors to save precious drinking water. Legal framework conditions for water reuse mitigate the effects of water scarcity due to climate change.
