The system we use today for harvesting rainwater with a rainwater barrel is similar to the one used in the Middle East more than 4,000 years ago. Back then, cisterns were used to trap and store large amounts of rainwater in areas that would otherwise be inhabitable due to a lack of water resources. The technology is quite straightforward. Rain water falls onto the roof of your home then it enters a series of gutters and downspouts before heading down the path to the nearest storm drain or ditch. The rain water barrel efficiently captures that valuable water and stores it for your future use.
Water barrels are an inexpensive way of using our planet’s most abundant natural resource. Water harvesting is seeing a boost in popularity due to a recent surge in the use of eco friendly alternatives. Rainwater barrels can be small, simple installations. They can also be massive, complex systems that use pumps and barrels to trap and store rain water directly from the down spouts of your home.
The most important step in determining if a rain barrel system will work for your home is to find out the type of roofing material used on your home. Some roofing materials contain toxins that will contaminate the water in the barrels. Materials like cedar shakes that have been treated, asbestos shingles, and even tar or gravel can cause problems for your water barrel system.
Next, the area directly below your gutters must be prepped. You will need a flat and level surface for your barrels. This step is crucial because once a water barrel is full, it is almost impossible to relocate. Deciding on the size and type of barrel you will need is simple, this solely depends on the amount of rain in your area and how much of that rainwater you wish to harvest.
Rain barrels come in many different sizes and shapes. For best results, use plastic barrels that are clean and sturdy. Food grade barrels are perfect because they usually come with UV protection. Other types of barrels can be used but must be watertight and rust proof. Harvested water is not made for drinking but if you plan to water a vegetable garden or fruit trees, it is essential for the water to be clean and toxin free.
Rain water barrels have changed the lives of many people in areas with little rain fall or long droughts. The water barrel technology is so simple it can be easily installed and maintained. Supplies cost very little and can be found locally as well as online. Many home improvement or gardening stores have them so you can definitely shop around and compare prices. Rainwater barrels are a perfect family project where children can have a hands-on experience in how a small ingenious system can reap so many benefits and rewards.
