Rainwater Harvesting

Saves you and the environment some green

Rainwater harvesting is “the process of intercepting storm-water runoff and putting it to beneficial use.” Pretty simple concept. Oddly enough, it is illegal in some states. The Colorado legislature, in its 2009 session, legalized rainwater harvesting for residents with private wells. Other states and municipalities are in the process of changing their laws. You’ll need to do a little research to determine what is lawful in your state. Whatever the case, I don’t think the police are going to show up at your door if you choose to harvest rainwater.

Why would I want to harvest rainwater anyway?

According to the EPA, a homeowner can save 1,300 gallons of water a month. That will help with your water bills or reduce stress on your well. You can use the water in your evaporative coolers, to water plants, your lawn, your pets or livestock. It reduces your carbon footprint by saving on electricity to pump water and then deliver it to your home. Besides, it simply makes good sense to have water stored to guard against times of drought or emergency.

You can begin by designing your home, buildings, and surrounding landscape to maximize the amount of rainwater catchment. You can do it like Jerry Brock of Monte Sereno, California and use four gravity-fed 5,000 gallon tanks. Or, there are companies like Rain Harvesting Systems (RHS) that specialize in elaborate and wonderful systems for your home or commercial building.

You can do it like people have been doing it for thousands of years—with some type of cistern. Cisterns, now, aren’t some Biblical clay container thing , but are usually some type of composite plastic. Here are some links to places you can buy one and also some “do it yourself” harvesting systems.

Bottom line: it can be as simple as putting a big bucket out under your rain gutter and using the water for dry spots on your lawn. Get an elaborate rainwater harvesting system or get a container with a cover (keeps mosquitoes from breeding and slows evaporation) and do your part to help your budget and your planet.
