Bioswales are channels designed to concentrate and convey stormwater runoff while removing debris and pollution. Bioswales can also be beneficial in recharging groundwater. Bioswales are typically vegetated, mulched, or xeriscaped. [1] .

A Bioswale or biofiltration swale is a narrow strip of a vegetated area that redirects and filters stormwater. A typical bioswale is long, linear and shallow and is used to collect runoff water from non-porous surfaces such as roads, parking lots, rooftops etc.

A bioswale is typically a vegetated channel with a parabolic or trapezoidal cross-section that can be used in place of a ditch to transport stormwater runoff from streets, parking lots and roofs. Bioswales are categorized by the type of vegetation used: Grassed swales are planted with turfgrass that is mowed.

In bioswale systems, the water running off from roofs and roads does not flow into the sewers but instead is led into the bioswale via above-ground gutters and/or ditches. Bioswales can be incorporated into the green infrastructure and can help enhance biodiversity and quality of life.

Sep 27, 2022 · A bioswale is a landscaping feature that removes silt and pollution from runoff stormwater. Bioswales are commonly used in urban areas to reduce the amount of stormwater runoff. They help filter water by trapping sediments and pollutants, which run off roads, parking lots, or other paved surfaces.

Bioswales are the most effective type of green infrastructure facility in slowing runoff velocity and cleansing water while recharging the underlying groundwater table. They have flexible siting requirements, allowing them to be integrated with medians, cul-de-sacs, bulb outs, and other public space or traffic calming strategies.

Jul 11, 2023 · For the curious and environmentally conscious homeowner, consider this your guide to bioswales: what they are, how to spot them, and how you can build one for your own home. What Is a Bioswale? Much like rain gardens, bioswales are meant to absorb water runoff.

Apr 26, 2024 · A bioswale is a vegetated ditch that allows for the collection of stormwater runoff. Bioswales are designed and engineered specifically to collect water. They are typically filled with vegetation and permeable materials like mulch.

Jul 23, 2023 · A bioswale is meticulously designed to concentrate and remove pollution and silt from surface runoff water, ultimately helping to protect our waterways. Each bioswale is characterized by a swaled drainage course, meaning it features a shallow, linear depression that guides water flow.

What is a Bioswale? Bioswales are linear, vegetated ditches which allow for the collection, conveyance , filtration and infiltration of stormwater. The can also be referred to as "grass swales," "vegetated swales," or "filter strips."
