Rain Water Harvesting

What is rainwater harvesting?

Rainwater harvesting is a centuries old technology and is basically the collection of rainwater which is used at a later time for different applications. The simplest and most common approach is to capture rain water from your roof, which is channeled through your eaves-trough and into a rain barrel.  The rain water is used for irrigation purposes instead of using municipally treated water.  The size of the rain barrel is dependant of the amount of water required, the size of your roof (also known as Catchment Area) and the rainfall patterns in your area.

Some Rainwater harvesting systems are more complex and capture significant amounts of water which can then be used not only for irrigation but for washing of clothes, bathing and in some areas possibly for drinking and food preparation.  Please be aware, however, that each country and municipality has different regulations on where and when rainwater can or cannot be used within the home or office. Please contact your local regulatory officials if you are considering a rainwater system to make sure you adhere to the necessary codes.    

Where is Rainwater Harvesting used?
