Bioswales: Not your grandmother’s storm sewer

A bioswale can be used in place of a traditional storm sewer. Planted with deep-rooted native grasses, flowers, and shrubs, bioswales beautify while helping water filter and infiltrate. Bioswales work best when they are placed in existing drainage areas. By design, bioswales infiltrate frequent smaller rain events and convey heavy rains in a non-erosive manner. They do not hold water on the surface for extended periods of time. In fact, bioswales can be a good solution for areas that have problems with ponding and standing water.

Bioswales are just one of many green stormwater management practices that communities can implement. Check this page for more examples, or visit the Iowa Storm Water Education Partnership’s website to learn more!
