Rainwater Harvesting is, by way of a simple explanation, the collection and holding of rainwater for a later use. Approximately one-half of municipal water is used on outdoor landscaping during the hot summer months. Think of how much money can be saved by using harvested rainwater instead of tap water. As an additional bonus, rainwater does not contain the added chemicals that are common in our city water supply.
Rainwater Harvesting systems can be as uncomplicated as a barrel at the bottom of a downspout, collecting rainwater to be used on plants. Some of the more elaborate systems utilize large cisterns, complicated networks of pipes, pumps, and reverse osmosis filtration systems. The size and complexity of the system is based on the quantity of rainwater to be stored and how it will be used.
A roof is the most common collection surface for household rainwater harvesting systems. As a rule of thumb, the smoother the collection surface, the better. The biggest obstacle would be roofing material whose chemicals cause problems with potable water. Tar-and-gravel as well as treated wood shingles are the most common offenders.
The storage tank used in rainwater harvesting can be as simple as a plastic barrel to as fanciful as a stone cistern. The size of the tank is based on how much water is to be used and how much rainfall is averaged where the system is located.
Gutters and pipes are necessary to move the rainwater from the collection surface to the storage tank. Adding pumps to larger tanks make accessing the water easier and a filtration system should be installed if the rainwater is to be used for cooking, drinking, bathing, etc.
Treatment of rainwater ensures that the water will be safe to use. See us when you need help with Rainwater Harvesting.
