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.
