Sustainable urban drainage systems for collecting, diverting and retaining surface runoff water
Traditional surface water drainage systems are often overloaded in case of heavy rain and thus cause flooding and damages. They can be developed further to “sustainable urban drainage systems” aiming on increasing their capacity e.g. when it comes to heavy rainfall and aligning them with natural water processes. There is a large collection of structural measures that belongs to this group measures. Some of them are listed in this catalogue. The system elements have in common that they require regular cleaning and maintenance.
Synergies may exist between heavy rain risk management measures and other development goals like environmental protection, health care, and economic performance. Harnessing them requires involvement of different actors, enforcement of exchange between you and them and holistic thinking.
