Description: WATERCOS displays the boundaries of water providers in Eastern Pima County and southern Pinal County, with the exception of Tucson Water. Contact Tucson Water for information regarding its service area or see the WATER_TW layer.
A water provider may be a private company, a municipal utility, or an entity financed by a special taxing district. Each year, water providers in Active Management Areas are required to provide ADWR with a description of their service area boundaries. ADWR can ask the provider to update these boundaries.
The franchise series of layers (F_*) also contain water companies.
Known Errors/Qualifications: This layer was originally provided by ADWR. Pima County has no specific information on how these boundaries were determined. ADWR is replacing older boundary definitions with new boundaries that reflect a 660 foot buffer around a water provider's network of transmission mains. Some providers perform the 660 foot buffer themselves, while others leave this step to ADWR. The 660 foot buffer is a critical distinction used to determine whether a well is inside or outside a service area. It is similar to the PAG product WATERSYS, containing overlapping polygons and new areas.
As a result of the ADWR changes, Pima County ITD GIS now maintains this layer.
Additionally, by filtering on DESIGNATED = "Y" this watercos layer can be displayed as "Assured Water Supply - Designated Service Provider"
