Description

A rain garden is a kind of garden that primarily serves as area for water control on a small-scale, especially in urban areas. Rain gardens are established in artificial surroundings and catch water runoff from roofs, roads and other sealed surfaces. Storm water runoff is drained into rain gardens, where it is stored for a certain period, and infiltrates either into the ground soil or flows into the sewage system.
