How Do You Calculate Rainfall For Harvesting?
Harvesting rainwater is an easy way for gardeners to supplement, or even replace, water requirements for their gardens. It’s free, it’s clean, and it helps conserve a resource. And every time it rains, there are thousands of gallons being wasted. It rolls off roofs and other structures, onto the ground, into ditches and storm drains. Instead of wasting it, people are collecting it. But in order to have the right-sized containers or catchment systems, it’s important to know how much water is coming off the roof. Follow these simple directions to arrive at the correct volume of water. The first thing to do is to figure the area of the structure. Begin by using the measuring tape, and measure your roof from one eave to the next. You can do this on the ground because it doesn’t matter whether your roof is flat or sloped. So let’s say the measurement is 30 feet X 50 feet. Write this down. You now have the measurements necessary to find the square footage of your roof.Multiply 30 feet times
