The majority of rainwater harvesting systems use the rooftop collection method to then store it in a water tank for use later. The surface area of the roof can be determined along with the average monthly rainfall to then estimate how much water your system can produce. There are many factors that can effect these calculations including what material your roof is made of, the slope of the area and the gutter system being used to then route it to your water storage tank.
