Water Harvesting Ordinances
Commercial Rainwater Harvesting
City of Tucson ordinance mandating that commercial developments provide at least 50% of their irrigation needs with harvested rainwater.
Residential Greywater Stub-Outs
City of Tucson ordinance mandating that all new home construction includes gray water stub-outs at time of building.
