A rain garden primarily serves for small-scale water management (e.g. storage, infiltration, pollution removal). They are often established within the built environment and collect water runoff from roofs, roads and other sealed surfaces. Water is temporarily stored in the raingarden and then infiltrates through the soil or flows into the sewer system. Raingardens are not restricted to certain climate zones, however the selected vegetation should be adapted to the local environmental and climate conditions.

Conditions for Implementation
  • Space needed
  • Selection of well-adapted plant species
  • Semi-regular maintenance
