Retention pond vs detention basin.

Description. Retention and infi ltration basins are open, usually fl at, areas of grass that are normally dry. In heavy rainfall they are used to store water for a short time and so they fi ll with water. They are often multi use; for example, they can double as play areas. Retention basins can have local areas of wetland depending on the design.Two issues that will be discussed in this Chapter are minimum spillway capacity, as spillway design will affect the duration of detention and therefore stormwater quantity and quality control, and pond forebay areas and capacity.
