Properly designed “rain gardens” can effectively trap and retain up to 99 percent of common pollutants in urban storm runoff, potentially improving water quality and promoting the conversion of some pollutants into less harmful compounds. This is according to new research scheduled for publication in the February 15, 2006 issue of the American Chemical Society journal, “Environmental Science and Technology”. The affordable, easy-to-design gardens could help solve one of the nation’s most pressing pollution problems.
Rainwater Capture: Design
This Water Environment Research Foundation report by LK Lampe, entitled “Post-project monitoring of BMPs/SUDS to determine performance and whole-life costs”, states that, over the past 20 years, the use of Best Management Practices (BMPs) in the United States has been instrumental in reducing both the detrimental impacts to receiving water quality and the exacerbated flooding caused by urbanization and storm water drainage. More recently, Sustainable Urban Drainage Systems (SUDS) have started to be used in the United Kingdom.
Capturing rainwater where if falls offers appealing technical alternatives to stormwater runoff capture than conventional end-of-pipe measures.
