Rain Barrels

ABOUT

What is a Rain Barrel?

A rain barrel is a system that collects and stores rainwater from the rooftop that would otherwise be lost to runoff and be diverted to streams and storm drains. Runoff can contribute to flooding in developed areas with a lot of impervious surface like roofs, sidewalks, parking lots and other surfaces that donít allow rain water to drain. Runoff carries pollutants that contribute to poor water quality that can affect the health of local waterways and even drinking water.

 

Because plants thrive on natural rainwater, which contains no chlorine, ammonia, fluoride or other chemicals from municipal water systems, the rainwater collected and stored in rain barrels is ideal for watering lawns and gardens.

 

Residential water use increases 40 to 50% during summer months ñ mostly due to outdoor water use.

 

A formula to remember: 1î of rain on a 1,000 SF roof yields 623 gallons of water. Calculate the yield of a roof by multiplying the square footage of the roof by 623 and divide by 1,000. Depending on the roof area, a rain barrel will fill up when there has been as little as 1/10th inch of rain.

 

Tennesseeís average rainfall is 54′ annually.
