Welcome, dear water enthusiasts! Ever wondered how to calculate water harvesting? Well, you’re about to get enlightened, and it’s as exciting as watching a cactus in a thunderstorm! (No cactuses were harmed in the making of this joke).
Water Harvesting Calculation Formula
The primary formula used for calculating water harvesting is represented as follows:
Water_Harvested = Rainfall (inches) x Area (square feet) x 0.623
