How much water can I collect?

Water consumption can vary widely due to different factors such as water usage for washing or bathing. This calculator will help you gauge how much water you can collect off your roof.

Annual Rainwater Volume Calculator

Annual rainfall (in inches) x 0.623 for collectable gallons x Roof area available for rainwater collection (in ft2) = Gallons collected annually.

Example: 1” x 1,000ft2 = 623 gallons

Please note that this is a rough guide only and is not an indication of how much water you will use.
