Rainwater harvesting is the process of collecting and storing rainwater for later use. Rain falls onto a roof, flows through gutters and downspouts, and is directed through filters to remove leaves and debris. The filtered water is then stored in a tank, where it can be used for drinking, bath/shower, landscaping and more! This simple process helps conserve the gift of rainwater, reduce runoff, and make better use of a valuable natural resource.

On average a 35,000-gallon rainwater water tank will last a family of four 2.5 to 4 months.
A 2,000-square-foot roof catches about 37,400 gallons of water from 30 inches of annual rainfall.
