Rain Gardens

Every time it rains, water runs to impervious surfaces such as roofs, driveways, road and parking lots, collecting pollutants along the way.

When stormwater (water that originated during precipitation events or from snow melt) moves over pavement, it picks up and carries with it fertilizer, pathogens, toxic contaminants, sediment and other pollutants before entering storm drains. These drains lead directly to waterways which lead to Long Island Sound. Polluted runoff can harm aquatic life and make the Sound unsuitable for fishing and swimming.

By building rain gardens at your home or business, you can reduce the amount of pollutants that leave your yard.  Rain gardens are expected to provide pollutant treatment. Pollutant treatment in rain gardens has been attributed to adsorption, decomposition, ion exchange, and volatilization.

To learn more about the benefits of building a rain garden check out the University of Connecticut Nemo Rain Garden page or use their Rain Garden App.
