Rainwater Harvesting
By: Mark Brown – President, Rain Catchers, LLC.
In this relatively new industry of rainwater harvesting I find myself constantly bombarded with questions from people trying to understand exactly what rainwater harvesting is, how it works, and why they should spend the money to do it. As time passes there are several questions that seem to be recurring, so I would like to take this opportunity to answer these questions and explain what rainwater harvesting is all about.
Rainwater harvesting is a viable solution to help solve our water crisis and storm water runoff problems here in Atlanta. A big part of my job is to continually educate people on the benefits of rainwater harvesting and the proper methods of installing the systems. We should all remember every rain drop is important to us, therefore we should be stewards of each drop.
For every 1000 square feet of roof space approximately 620 gallons of water can be collected. This means on a 2000 square foot roof 1240 gallons of water can be collected from a 1” rain event. During the extreme drought of 2007 this one home would have produced 37,200 gallons of free unrestricted water.
