Apache Junction Water System Expansion: Planning for Growth at Scale
As development accelerates around Apache Junction, the need for reliable, long-term water infrastructure becomes critical. This regional master planning effort focused on expanding the existing water system to support approximately 8,000 acres of development, accommodating up to 10,000 new homes along with future commercial uses.
The challenge was not just meeting immediate demand, but building a system that can grow with the community while maintaining reliability and flexibility over time.
Designing a System Built for Capacity and Redundancy
Our team developed a comprehensive hydraulic model to guide system planning and identify future needs, including storage, pumping, and connections to both existing and planned water treatment facilities. Redundant groundwater supply options were incorporated to strengthen system resilience and ensure consistent service.
Key infrastructure includes a 3.4 million-gallon potable water storage tank, a high-capacity booster pump station, and new well facilities. Transmission improvements along Ironwood Drive include several miles of large-diameter water mains, designed to move water efficiently across the system while navigating complex crossings such as the CAP canal and regional drainage features.
Supporting Delivery from Planning Through Construction
In addition to planning and design, our role extended into construction administration and inspection for major system components. Working within a CMAR delivery framework, our team supported submittal and RFI review, coordinated field observations and inspections, and maintained oversight of schedule, cost, and documentation.
By aligning long-range planning with active construction support, the project delivers infrastructure that not only meets current demand, but positions the region for continued growth with a reliable and adaptable water system.
