DEFINITION: The collection and storage of roof rainwater for on-site reuse. The water makes its way through rainwater systems and fine mesh filters, into a tank, usually underground, and then is pumped from that tank to be used in a number of non-potable applications. This can reduce the demand on the potable water supply provided by the water companies significantly and reduce water costs.
