The bioswale is a sophisticated filter that handles stormwater runoff. Using intricate landscaping techniques, swales and basins are able to remove impurities, debris, and pollution from rainwater.
To do this they require a combination of factors including proper soil media, and a commitment to best practices. The well-designed basin or swale may consist of carefully orchestrated slopes, as well as vegetation, and soil that blends clay and sand to filter out impurities.
