RISA: Published Rainwater Action Plan

The increasing urbanization and effects of climate change are creating tremendous challenges for managing the waters of Hamburg. The Department of Environment and Energy together with HAMBURG WATER have opted for the RISA project concepts and solutions for a sustainable use of rainwater management.

The RISA project was launched in 2009 and successfully completed in 2015 in order to respond to the increasing conflict between urban development and water resources management. The results of the extensive work are summarized in the "RISA: Rainwater Action Plan 2030".
