One of the simplest and most cost effective ways to use water wisely is to harvest rainwater. The Environmental Protection Agency of the United States reports that about 450 gallons of water runs off a typical roof each summer month. Diverting runoff into barrels or cisterns makes hundreds of gallons of water available to homeowners and decreases storm runoff.
Rain Barrels
The easiest and least expensive way to gather rainwater is to attach a rain barrel to your downspout. As rain flows down your roof and into your guttering, the rain barrel collects and stores the water. This water is perfect for irrigating lawns and gardens. Some people discard the first 10 gallons of each storm collection out of concern about roofing tile pollution. Barrels are equipped with a spigot at the bottom which can be attached to a hose. Rain barrels can be purchased at local garden stores. Many counties sell rain barrels at reduced prices. Consumers can also make a rain barrel for as little as $20 to $30; a significant savings over commercially made barrels. Instructions are easily found on the Internet and some communities hold rain barrel making workshops.
Cisterns
The idea of catching and storing rainwater is ancient. Until the turn of the 20th century, cisterns were an ordinary part of an American homeowner’s property. Underground containers gathered and stored rainwater for use in most aspects of daily life. There has been a resurgence of interest in using cisterns. They are now commonly used in Australia and the technology has made its way to other countries where water conservation is a key concern.
Harvesting and reusing rainwater makes good sense. Try out a rain barrel and save water now.
