RISA - Rainwater InfraStructure Adaptation of Hamburg

RISA - RegenInfraStrukturAnpassung

The aim of the project is to implement a sustainable rainwater management in Hamburg that is adjusted to the heavy rainfalls caused by the global climate change. The project involves the analysis of pilot projects and the development of the city's rainwater structure plan 2030 (Strukturplan Regenwasser 2030) (Reference 1) that will serve as a basis for the Integrated RainWater Management (IRWM) in Hamburg (Reference 5).
