Finally! A bioswale that works.
The above swale is still pulling its weight after five years!
The bioswale was installed in February 2010. The total cost was $74,000. Five years later, it continues to pay off. The bioswale has successfully stopped floods from occurring year after year, and also continues to reduce pollutants from stormwater runoff by at least 69% as shown below. Testing for pollutants was conducted five years after installation, on March 23, 2015. See the results below. Click Here to view the case study on this site. 2016 Update now available. Was determined it was time to change out the EarthLite™ Stormwater Filter Media.
