Detention basin definition
Detention basin means a type of storage practice used to detain or slow storm water run-off and then release it through a positive outlet.
Detention basin means an excavation into soils hav- ing low permeability or installed with a liner having low perme- ability, not having a permanent pool of water, designed and con- structed to temporarily hold storm water to reduce peak discharges of storm water for flood control and to allow for the physical settling of pollutants.
Detention basin means a stormwater management facility which temporarily impounds and discharges runoff through an outlet to a downstream channel. Infiltration is negligible when compared to the outlet structure discharge rates. The facility is normally dry during periods of no rainfall.
Examples of Detention basin in a sentence
Detention basin and related facilities for water quality and storm water purposes are included with the Association Open Space and Common Areas.
Detention basin discharges into the diversion channel must be reduced (<3000 cfs) to provide a minimum of 1 foot of freeboard under the East Yosemite Avenue and Olive Avenue bridges.
Detention basin release structures shall be inspected on a monthly basis and maintained in a condition that freely allows the release of runoff as designed.
More Definitions of Detention basin
Detention basin means an area designed to detain peak flows from storm water runoff and to regulate release rates of that water into the storm drainage system, also allowing debris to settle out. Detention basin outlets may also be connected to downstream storm drains. Flows entering detention basins are released via outlet piping.
Detention basin or "detention facility" means a human-made impoundment area made by constructing an embankment, or excavating a pit, or both, for the purpose of temporarily storing stormwater.
Detention basin means a reservoir, which temporarily contains storm water runoff and releases it gradually into a watercourse or storm water facility.
Detention basin means a stormwater management facility designed to protect against flooding and, in some cases, downstream erosion by storing water for a limited period of a time. Detention basins do not retain a significant permanent pool of water between runoff events.
Detention basin means a facility constructed to restrict the flow of stormwater to a prescribed maximum rate, and to detain concurrently the excess waters that accumulate behind the controlling outlet.
Detention basin means a temporary storage facility for excess storm runoff designed in accordance with the Engineering Standards and containing at a minimum an inlet and outlet and designed for the purpose of (1) attenuating and detaining excess storm runoff, and (2) regulating the flow of such excess storm runoff so as to reduce stormwater-related damage downstream, and (3) enhancing the water quality of such excess storm runoff by providing filtration, sedimentation, and oil-removing apparatus.
Detention basin means a facility designed to temporarily store runoff from rainfall or snow melt, releasing the stored water at a controlled rate until the basin is empty. The outlet or control structure is located at the bottom of the facility so that the basin is dry after the runoff event. (See also Detention Pond, Retention Basin and Retention Pond).
