Rain Barrels

What is a rain barrel?

A rain barrel or cistern is a rainwater collection system that stores rooftop runoff to be used later for activities such as lawn and garden watering, car washing, and even window cleaning (see photo on left).

Why use a rain barrel?

Residential irrigation can account for 40% of domestic water consumption in a given area. This can be a problem particularly in summer, when the majority of outdoor water use occurs, and also the time when there is likely to be a water shortage. Collecting rainwater from your roof during storms by using a rain barrel can not only lower your water bills, but also help to decrease water demand during the hot summer months.  Rainwater collection and reuse is beneficial to the environment because the stored water would otherwise run off into the storm sewers or road side ditch, bringing pollutants such as oil and grease, bacteria, and nutrients with it. Once water gets into a storm sewer or road side ditch, it eventually ends up in our streams and rivers. Also, the more rainwater that is reused, the less need there is for chlorinated or chemically treated tap water.

Where can I get one?

Call your local garden center to see if they carry them or can order a rain barrel for you.  You can also order them from suppliers on the internet. Or, if you are feeling especially creative, you can make your own rain barrel using a large trash can, agricultural supply container, or other large container (see Urban Rain Barrel Assembly Instructions). Barrel sizes range from 50 to 250 gallons, and prices range from $50 to $325. You can also contact your local County Soil and Water Conservation District for more rain barrel information.

How do I install a rain barrel?

Most rain barrels are easy to install; however, actual installation methods may vary depending on the individual brand of rain barrel.  Installation of a typical barrel will involve disconnecting your downspout, cutting off a portion of the downspout and redirecting it into the top of the barrel. Most rain barrels have an overflow pipe that redirects the rainwater back into the downspout or onto your lawn or other surface in the event the barrel becomes full. Other features may include safety features, spigots, connector barrels, mosquito proofing, and even water filters. Always be sure to empty your barrel before winter comes so you don't end up with a barrel full of ice!
