What is a swale?

A swale is a shallow, vegetated depression or ditch designed to manage stormwater runoff. It helps to slow down the flow of rainwater, allowing it to infiltrate into the ground more effectively and reduce erosion. Swales are commonly used in residential and commercial developments, as well as along roads and highways, to help control water pollution and flooding. They are typically planted with grasses or other vegetation to help filter out sediment and pollutants from the runoff. Swales are a cost-effective and environmentally friendly solution for managing stormwater in urban and suburban areas.
