Landscape design service and B&B. ZonaGardens advocates complete rainwater harvesting design solutions that incorporate desert-adapted plants into designs that store rainwater in the ground and/or in above-ground storage tanks.
A rainwater collection and storage system is investigated, focusing on water quality at various points: from roof runoff to an underground concrete cistern. A prototype sand filtration system (designed to improve water quality) is built and then tested. The result is complete removal of suspended solids.
The rainwater harvesting system at Zilker Botanical Gardens will benefit not only garden plants, but will help homeowners understand whether or not a rainwater harvesting system is right for them, and which features and types of materials they prefer.
