Best Management Practices in PRWD
Best Management Practices that you can find throughout the District include:
Rain gardens are vegetated shallow depressions designed to capture and absorb rainwater. The soil in rain gardens naturally removes pollutants like phosphorus, nitrogen, and heavy metals from the water. This helps prevent pollutants form entering nearby lakes and streams where they can cause unwanted algae growth and degrade water quality. Rain gardens contain plants with long roots that should soak up all water within 48 hours of an average rainfall.
Bioretention basins are shallow impoundments designed to capture and absorb rainwater, similar to rain gardens. Some basins also use underground drains to increase the amount of rainwater they can capture.
Underground Infiltration Systems
Underground Infiltration Systems are designed to capture and store rainwater inside underground pipes and rock beds. Eventually, the stored water soaks into surrounding soils through perforations in the pipes and spaces between rocks and into the surrounding soil.
