Dry detention ponds are vegetated detention basins designed for short-term temporal water storage during heavy rain occasions. Stormwater fills up the detention pond and detained water then flows into the sewer system. In periods of no heavy rainfall, the detention ponds are dry and can be used as public green areas. The natural landscape in which the detention pond is being implemented contains a heterogeneous surface with slightly elevated areas and lower parts in proximity, forming a mosaic of micro conditions. Water stays in the lower parts for some time until it infiltrates or evaporates.
Benefits
