Storm water is typically channeled to a retention basin through a system of street and/or parking lot storm drains, and a network of drain channels or underground pipes.. The basins are designed to allow relatively large flows of water to enter, but discharges to receiving waters are limited by outlet structures that function only during very large storm eve
Dry pond on brook to reduce floods, near Děčín, Czech Republic. A detention basin or retarding basin is an excavated area installed on, or adjacent to, tributaries of rivers, streams, lakes or bays to protect against flooding and, in some cases, downstream erosion by storing water for a limited period of time.
It is distinguished from a detention basin, sometimes called a dry pond, which is designed to discharge to a downstream water body (although it may incidentally infiltrate some of its volume to groundwater); and from a retention basin, which is designed to include a permanent pool of water.
The outlet is generally a restricted-flow drain from the detention vessel, with a weir for containing detritus. [3] Detention vessels delay water's delivery downstream, and possibly creates a later water level peak post-rainfall. It is important to consider timing of water release and the types of reservoirs feeding a waterway. [7]
The problem began in 2023 when a flood revealed that the land beneath four homes in the neighborhood — including Sturgon's — was originally a retention pond designed to protect the community ...
A sediment basin is a temporary pond built on a construction site to capture eroded or disturbed soil that is washed off during rain storms, and protect the water quality of a nearby stream, river, lake, or bay. The sediment-laden soil settles in the pond before the runoff is discharged.
Jul. 25—After some heated discussion about placing a storm water retention pond near the city pool parking lot in the Albert Lea City Council's work session Monday, the council voted 6-1 during ...
A small agricultural retention pond in Swarzynice, Poland. In agriculture practices, treatment ponds can be created to reduce nutrient runoff from reaching local streams or groundwater storages. Pollutants that enter ponds can often be mitigated by natural sedimentation and other biological and chemical activities within the water.
