How it Works

A man-made or constructed wetland or water garden is a large, planted area between dry land and a stream that's covered in shallow water. Plants that thrive in wet conditions filter out the pollution carried in stormwater runoff that enters this area.

Best Location

  • Low-lying land that's wet year-round
  • A lot of sunlight to support the plants
  • Good for open space near a stream, creek, or river


  • One of the most effective ways to manage stormwater
  • Improves water quality 
  • Creates a healthy ecosystem 
  • Helps store rainwater
