More and more people are investing their dollars in rain barrels. The main benefit is reducing runoff into storm drains.
Check with your city and or county for possible incentive programs to save you money.
When placing your barrel be precise, because once filled a 55 gallon drum weighs 400 pounds. Water savings amount to pennies on the dollar.
If you could catch all of the 600 gallons of runoff of an inch of rain falling over a 1,000 square foot roof, the water savings would be roughly a dollar and a quarter.
If you held Portland's annual rainfall of 37 inches, the water savings would be about fifty dollars. People using rain barrels say they feel good about helping the environment and putting runoff back into the soil.
Reducing runoff into storm drains is considered an important part of going green.
