For centuries, harvesting rain water has been an essential common practice for everyday life. Even today, cisterns and other rain harvesting systems are common in India, Australia, Europe, the Bahamas and countless third world countries. There are in fact many people around the world who still depend primarily on rain water as the water they need for daily living. In addition to offering a practical solution when water supplies become limited or access becomes interrupted, rain water harvesting systems not only contain storm water runoff, but these systems can store water for irrigation, alternative or emergency use for flushing toilets, pressure washing, or washing clothes and cars. Stored rain water can even be purified and used for normal water. With a variety of filtration and processing systems to choose from, there are few limits to the plethora of ways a stored rain water reserve can be used to backup your regular normal water. The near neutral PH of filtered and processed rain water makes it safe for a variety of domestic and commercial applications. Rainwater is soft water, so it is healthy for appliances. Rainwater is free and so can reduce overhead for commercial enterprises, not to mention that using rain water recycles our natural resources.
What is a Rainwater Harvesting System?
Depending on the size of the use will decide how big the program needs to be. Your rain water collection program can be as simple as one or more rain water cisterns, or rain water barrels connected to the downspouts of your home gutters. Or if you prefer, you can construct a more elaborate program piece by piece. A complete program for rain water collection could include either above ground or below ground storage tanks. While above ground tanks are easier to install, they can definitely be more expensive and less attractive.
