Construction Begins on Two-Phase Deer Valley Water Treatment Plant Rehabilitation Project

The Water Services team with McCarthy Building Companies Inc. recently began construction on the City of Phoenix Deer Valley Water Treatment Plant, located in north central Phoenix. The two-phase $37.2 million rehabilitation project focuses on updating the solids treatment portion of the plant, which intakes and filters water from the Arizona Canal, to increase plant efficiencies. The project also includes the addition of a new electrical building at the site.

The Deer Valley Water Treatment Plant rehabilitation project addresses aging water infrastructure issues by replacing the existing conveyors and making improvements to the dewatering building with updated equipment to increase efficiency. Additionally, the project includes the construction of a new east electrical building that will contain electrical distribution equipment to service existing buildings on the eastern portion of the plant’s site.   


“The rehabilitation program allows for maintaining the integrity of the water treatment facilities to provide safe and reliable drinking water to our residents. Water Services has full confidence in the successful completion of the Deer Valley Water Treatment Plant Rehabilitation project,” said Jorge Navarro, City of Phoenix project manager.


Phase one of the project, marked for completion in late 2025, includes:

  • Removal and replacement of 15 existing solids classifying conveyors

  • Lowering the second-floor mezzanine of the dewatering building by two feet to better allow for unit maintenance

  • Conversion of an existing dumpster bay and modification to a truck bay with weigh scales


Phase two, marked for completion in late 2027, includes:

  • Construction of the new east electrical building, to supply 5kV of power, feeding into four on-site buildings


Originally built in 1964, the plant processes an average daily flow of 100 million gallons per day (MGD) and will remain operational throughout construction, ensuring current and ongoing community water needs are met. This rehabilitation will further the plant’s efficiency in alignment with Phoenix’s goal to deliver the highest quality water for residential and commercial use in central Phoenix. McCarthy previously constructed the plant’s east basins in 2010, which now serve as the plant’s primary system.


“Having previously worked at the Deer Valley Water Treatment Plant, we are in a position to ensure the safe and effective updating of the plant’s aging equipment while the facility continues to deliver high volumes of water to Phoenix residents,” said Pat Payne, vice president of operations for McCarthy Building Companies. “As the Valley continues to experience growth, we are proud to support the City of Phoenix in addressing the current and future needs of the community and delivering clean water.”


McCarthy is serving as construction manager at-risk on the project and Wilson Engineers Inc. is the engineer of record. The project’s trade partners include Industrial Power Solutions, S&H Steel, MLM Conveying Systems, Progressive Roofing, Stone Cold Masonry, PPS Coatings and Tempe Mechanical.
