How much water do I use?
The first thing you'll want to consider when choosing your perfect rain barrel is how much water you typically use on your lawn and garden. This will help you determine how much water you'll need your water barrel to store to be useful and efficient. Figuring out how much water you use in your lawn and garden is fairly easy using the following guidelines:
- 1 small watering can = 1 liter (0.26 gallons)
- 1 medium watering can = 6 liters (1.56 gallons)
- 1 large watering can = 12 liters (3.12 gallons)
- 1 sprinkler, full flow, 30 minutes = 550 liters (143 gallons)
How much water will I be able to "harvest?"
Your decision on how many rain barrels to use will affect how much water you'll be able to harvest from your roof. For example, in a perfect world, with rain barrels under all of your downspouts and harvesting all of the runoff from your roof, 1 inch of rain (on a 1,000-sq.-ft. roof) can yield approximately 600 gallons of water. Since it's not a perfect world, you'll want to subtract about 20 percent of that total due to gutter leaks and other things to get a more accurate total (approx. 480 gallons). Based on those numbers, you can better predict how many plastic rain barrels you'll need to store the kind of water you'll need to supply to your lawn and garden. By doing a quick Internet search, you'll easily be able to find indices for your state's average rainfall in any given month, and by knowing the square footage of your roof, you'll be able to calculate, using the above formula, a good estimate of the amount of water you'll be able to harvest.
