Rain Gardens are gardens that temporarily store rainwater and runoff and cleans water of hydrocarbons,oil, heavy metals, phosphorous, fertilizers and other pollutants that would normally find their way to the sewer and perhaps our rivers and waterways.
Rainwater flow across roofs, driveways or chemically treated lawn and picks up pollutants. Then these pollutants run into the street and into the sewers that directly feed into are creek and streams. Rain Garden will intercept and naturally clean and infiltrate the water. This reduces large quantities of water and contaminants from reaching the treatment plant and in others locations it prevents stormwater from running directly into rivers and streams.
DCVA received a grant from the National Fish and Wildlife Foundation (NFWF) to support installing rain gardens in the Naylor's Run Micro-Watershed. DCVA along with Havertown's EAC Hav-A-Rain-Garden built highly visible green Stormwater Infrastructure (GSI) in an urban and suburban landscape within the Naylor's Run Watershed in Delaware County. They installed rain gardens and GSI will collect, treat, detain, and recharge stormwater runoff before it reached naylor's run.
