A rain barrel collects and stores rainwater from rooftops to use later for lawn and garden watering. Water collected in a rain barrel would normally pour off your roof directly or flow through roof gutter downspouts and become stormwater runoff. Stormwater runoff is the leading type of residential non-point source pollution. Depending on your yard, this runoff can travel onto paved surfaces and eventually into a storm drain.
Residential water use increases 40 to 50% during summer months due to outdoor water use, so use the water you collect in your rain barrel in the spring to water your plants.
