Rainwater Harvesting Calculator
The Rainwater Harvesting Calculator helps estimate the potential amount of rainwater that can be collected from your roof. By entering the dimensions of your roof and the average annual rainfall for your area, you can determine how many gallons of water can be harvested each year. This tool promotes water conservation and sustainability, enabling users to make informed decisions about using rainwater for irrigation, landscaping, or household needs. Understanding how much rainwater you can collect can aid in reducing water bills and enhancing self-sufficiency.
The formula for calculating the rainwater harvested (RWH) is: RWH = (L * W * ARF) / 12 * 7.48052. Here, RWH is the harvested rainwater in gallons, L is the roof length in feet, W is the roof width in feet, and ARF is the annual rainfall in inches. The division by 12 converts the annual rainfall from inches to feet, and the multiplication by 7.48052 converts cubic feet to gallons. This calculation helps to quantify the potential water savings available from your roof.
