In this LEED platinum home, rainwater is harvested and reutilized for both irrigation and for flushing indoor toilets.
The captured rainwater from the home’s upper metal roofs are conveyed by gravity to a converted pool now water storage cistern.
The Pool-to-cistern conversion holds 18,000 gallons of captured rainwater. The irrigation reuse water is untreated other then sediment filtration for the rooftop vegetation. The reuse water entering the house receives UV purification prior to use in the toilets.
