This section provides an overview for detention basins as well as their applications and principles. Also, please take a look at the list of 4 detention basin manufacturers and their company rankings.
A detention basin is a disaster prevention facility that compensates for the water retention function of the ground that has been impaired by land development. If no regulating reservoirs are in place, the water retention function of the land is temporarily impaired by development in urban areas. As the water retention function of the land decreases, rainwater overflowing from the land flows into rivers and underground facilities in urban areas, causing human casualties and property damage. Therefore, an underground detention basin is constructed to temporarily store rainwater and control the amount of rainwater runoff.
In addition to an detention basin, there are detention and control basins that control the flow of rivers.
Recreational reservoirs and regulating reservoirs control river levels by allowing river water to flow in through overflow embankments when the river level rises. Overflow levees are constructed one level lower than the land surrounding the reservoir. These facilities differ in the method of maintenance of the facilities.
In the past, forests and fields were abundant and the water retention capacity of the land was sufficient. Recently, however, as land has been converted to residential land, rainwater no longer soaks into the ground. The rain that does fall flows directly into rivers through gutters and rainwater trunk lines. Then, when large amounts of rain fall, rivers overflow and rainwater overflows from gutters.
To solve these problems, rivers and rainwater channels have been covered with concrete, but the rivers, which are the inflow points for rainwater, have a fixed amount of rainwater they can accept. However, the rivers that receive rainwater have to be widened in order to accommodate more rainwater. In urban areas, however, this is not practical because the width of rivers is limited.
Detention basins can be constructed even in urban areas, and facilities such as baseball fields can be built on top of the detention basins. Since the purpose of detention basins are to prevent damage from flooding, they are also known as flood control basins.
There are three general types of detention basins: the moated type, the underground box type, and the underground tunnel type.
Other types of regulating reservoirs, such as dam-type and pool-type reservoirs, are often constructed in mountainous areas.
