How much water do I collect?
The formula below let's you calculate the storm water run off from our roof in the first 1.25 inch of rain fall.
Volume of water in cubic feet = Area of rainfall in square feet x rainfall in inches x 1/12 inches to feet conversion x 7.48052 cubic feet to gallon conversion |
For example:
1300 sqft roof
1.25 inches of rain
1300 x 1.25 x 1/12 x 7.48052 = 1012 Gallons |
How much water ends up in my rain barrel?
If you have four downspouts at your house each downspout gets about 250 gallons. Our diverter collects roughly 80% of the water. Which means that you barrel will fill up pretty quick. We recommend at least 2 barrels
per home. Our impact calculation gives you more details about your yearly savings under the assumption you use the rain barrel frequently. |
