Abstract: Abstract A storage and detention facility (pond or basin) is a low‐lying area (natural or constructed), which is designed to hold a specific amount of runoff temporarily and used to attenuate peak flow rate. Stormwater runoff is released to downstream conveyances in a controlled manner such that downstream flooding and other adverse impacts are prevented or alleviated. Detention facilities can be surface and underground storage basins, and they can be classified as wet or dry ponds. Detention storage design need consider determination of the size of pond, site selection, design of outflow structure, construction of pond, maintenance cost, and estimates of service life. The most common outlet structures for detention ponds can be of orifice‐type, weir‐type, or a combination of the two. The pond should be located where the topography of the site allows for maximum storage at minimum construction cost. Multiple ponds may be necessary to achieve the detention requirement.
