Phoenix Plant Rehabilitation Earns Arizona Project of the Year Honors

Why It Matters

The award spotlights how strategic infrastructure rehab can safeguard water delivery in arid markets, reinforcing utility resilience amid tightening water supplies. It signals growing investor and regulator focus on modernizing aging treatment assets.

Key Takeaways

• PCL and Carollo rehabilitated Phoenix's 24th Street plant
• Project serves ~400,000 residents in northern Phoenix
• Award highlights resilience amid Colorado River drought
• Construction manager at risk model met timeline despite supply chain issues
• Recognizes growing role of rehab projects in arid regions

Pulse Analysis

The Arizona Water Association’s Project of the Year honor underscores a shifting priority for utilities in the Southwest: securing water supply through targeted infrastructure upgrades. As climate change intensifies drought conditions and Colorado River allocations shrink, municipalities are forced to rethink legacy treatment plants. Recognizing projects that blend technical innovation with operational continuity, the award validates a model where public‑private collaboration can accelerate resilience without sacrificing service reliability.

The 24th Street plant rehabilitation exemplifies a construction‑manager‑at‑risk approach that mitigated pandemic‑era supply chain disruptions. By aligning PCL’s procurement expertise with Carollo Engineers’ design acumen, the team delivered critical upgrades—such as advanced filtration modules and redundant pump stations—on schedule. Maintaining uninterrupted water flow to 400,000 residents required phased construction and real‑time monitoring, illustrating how meticulous planning can overcome material shortages while preserving public health.

Beyond Phoenix, the project signals a broader industry trend: utilities are increasingly investing in rehabilitation rather than new builds to extend asset life and improve flexibility. This strategy reduces capital outlays, shortens permitting timelines, and leverages existing rights‑of‑way, making it attractive to regulators and investors alike. As water scarcity intensifies across the western United States, similar projects are likely to become benchmarks for resilient, cost‑effective water infrastructure modernization.
