Rain gardens are a good way for homeowners and businesses to reduce polluted rain water runoff by simply planting a specialized garden. Rain gardens are a useful infiltration technique in which water is captured in a garden that features native plantings. The rain water has a chance to slowly filter into the ground rather than run off into the storm sewer. It is a popular way to reduce nonpoint source pollution and protect our lakes and streams.
