Global Water Seeks 20% Boost in Assured Supply for Phoenix Growth Corridor
Event summary
- Global Water's GW-Santa Cruz subsidiary seeks to increase assured water supply by 20% (to 27,466 acre-feet) via DAWS application.
- Proposed expansion would support population growth from 78,000 to ~177,000 in Maricopa service area.
- GW-Ocotillo files separate DAWS application for 1,128 acre-feet supply in Pima County.
- Applications leverage recycled water and Ag-to-Urban Groundwater Savings Credits.
- ADWR decisions expected by Q4 2027.
The big picture
This filing reflects Arizona's push to balance rapid urbanization with groundwater sustainability. Global Water's Total Water Management approach positions it uniquely in this transition, though success depends on regulatory cooperation and credit program execution. The combined service areas represent over 70,000 connections—scale that matters in water-scarce growth corridors.
