Rain Barrels

What are Rain Barrels?

Rain barrels are containers used to collect a portion of the rainwater that flows from your rooftop and stores it for uses such as watering your lawn and garden. By capturing water from downspouts that would otherwise discharge onto a paved surface, rain barrels can reduce the amount of polluted stormwater runoff reaching local streams.  You can build your own rain barrel or purchase a pre-assembled rain barrel and install it yourself. Rain barrels are sold at most major hardware stores, garden centers and online vendors. A range of materials, designs, and colors are available.
