Rain gardens are gardens with native perennials and shrubs planted in a depressed area of land and are designed to soak in and store stormwater runoff from roofs, driveways, lawns, etc.
Rain gardens are an attractive way to reduce storm water pollution and improve water quality. They help keep polluted water out of our sewers that would need to be treated at a wastewater plant, or would overflow to a water body. Storm water becomes polluted when it flows over pavement and comes into contact with automotive fluids, sediment, trash, pet waste, etc. Pollutants can be absorbed by the deep plant roots instead of contaminating our rivers, lakes and streams.
