Dry pond on brook to reducing 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.
A stormwater detention vault is an underground structure designed to manage excess stormwater runoff on a developed site, often in an urban setting. This type of best management practice may be selected when there is insufficient space on the site to infiltrate the runoff or build a surface facility such as a detention basin or retention basin .
It is distinguished from a detention basin, sometimes called a "dry pond", which temporarily stores water after a storm, but eventually empties out at a controlled rate to a downstream water body. It also differs from an infiltration basin which is designed to direct stormwater to groundwater through permeable soils.
The system may consist of a single pond or several ponds in a series, each pond playing a different role in the removal of pollutants. After treatment, the effluent may be returned to surface water or reused as irrigation water (or reclaimed water ) if the effluent meets the required effluent standards (e.g. sufficiently low levels of pathogens ).
Recently completed infiltration basin for stormwater collection. An infiltration basin (or recharge basin) is a form of engineered sump [1] or percolation pond [2] that is used to manage stormwater runoff, prevent flooding and downstream erosion, and improve water quality in an adjacent river, stream, lake or bay.
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 ...
