A stormwater basin is a vegetated depression designed to slow runoff, remove pollutants and store stormwater as a permanent pool that would otherwise cause flooding and erosion.

A stormwater basin is a vegetated depression designed to collect and store runoff as a permanent pool of water that removes pollutants through settling and biological uptake. A detention basin slows the flow before releasing it into a smaller outlet. An infiltration basin operates much like a detention basin, but it is designed to infiltrate runoff into permeable soil. While basins have traditionally been mowed systems with concrete channels, newer designs incorporate native vegetation that allow for greater filtration and improved water quality.
