Stormwater Management

Becomes an important issue. Until 2020 another 1 billion people will live in cities (UN/ DESA 2003). The increase of urban areas forces to give high priority to decentralized measures of rainwater retention and new strategies in water supply and wastewater management. Although in the natural landscape most precipitation is evaporated or transpired, in urban areas, evapotranspiration is greatly decreased and rainwater is instead swiftly directed into the sewer system and to receiving water bodies. The Institute of Physics Building is not connected to rainwater sewers, as one main goal of the decentralized rainwater harvesting is a retention of rainwater in order to reduce storm water flows into sewer systems.
