Rainwater harvesting is the accumulating and storing of rainwater for reuse before it reaches the aquifer. It has been used to provide drinking water, water for livestock, water for irrigation, as well as other typical uses. Rainwater collected from the roofs of houses and local institutions can make an important contribution to the availability of drinking water. Rainwater Harvesting conserves water by making use of a sustainable renewable resource. Every gallon of rainwater used for irrigation is one less gallon of municipal or well water used.

Rainwater harvesting can ensure an independent water supply during water restrictions, despite climate change forecast. It produces beneficial effects by reducing peak storm water runoff and processing costs. Rainwater harvesting systems are simple to install and operate. They provide water at the point of consumption. Other advantages?
