WATER SUPPLIER
Hassayampa Ranch
Maricopa County
The project would likely partner with Global Water Resources, the public service water provider for the area, though the tenant could instead drill its own wells or build on-site storage/recycling; the site is within the Phoenix Active Management Area subject to Arizona's groundwater management law. Maricopa County itself explicitly does not supply water, fire or sewer service to unincorporated sites.
Key data: "would likely partner with Global Water Resources"; Phoenix AMA; "Maricopa County does not supply water, fire or sewer services"
CORROBORATEDLimitation: No executed water service agreement and no ADWR assured/adequate water supply determination located. County non-provision language is from https://www.maricopa.gov/AgendaCenter/ViewFile/Item/10227?fileID=100092
