Release Date: May 11, 2022

AZ Water Awards 2022

PHOENIX – Carollo Engineers, its clients, and project partners have been honored by the AZ Water Association (AZ Water) with Project of the Year awards in two categories. The 2022 awards were presented at the AZ Water 95th Annual Conference & Exhibition in Phoenix, Arizona, on Wednesday, April 13.

The Project of the Year Awards recognize outstanding engineering excellence and achievement. Each of the award-winning projects received high marks for their innovative application of new or existing techniques, meaningful social and/or economic benefits, successful execution despite significant project complexity, and meeting or exceeding the owner’s budget and schedule goals.

Carollo, with their clients and partners, won the following awards:

  • Water Treatment Project of the Year: Val Vista Water Treatment Plant (VVWTP) Rehabilitation ProjectThis project included significant facility rehabilitation efforts at the Val Vista Water Treatment Plant, while working within very tight shutdown windows to maintain plant production requirements. A comprehensive condition assessment was performed at the initiation of the project to confirm the scope. The subsequent design and construction included replacement of the East Inlet 5kV Switchgear housed in a new building, replacement of ferric chloride storage and feed equipment, replacement of final sedimentation sludge collectors and launders, and conversion of filters to granular activated carbon (GAC) filter adsorbers. As a result of the strategic asset replacements and upgrades, the VVWTP produces more reliable and higher-quality drinking water for its customers.Carollo was recognized alongside the City of Phoenix, the City of Mesa, Sundt Construction, EIC Engineers, and Wilson Electric.
  • Water System Project of the Year: North Avondale Water Supply ProjectThe North Avondale Water Supply Project was honored for helping the City of Avondale, one of the fastest growing communities in the West Valley, augment its surface water supply. The project, initiated as a result of the Carollo-led 2018 Integrated Utility Master Plan (IUMP), resulted in a new interconnect turnout facility, which provided a cost-effective approach to bring a new surface water supply to the City and significantly increase the operational flexibility of the water system. It includes more than 7,000 feet of conveyance water mains and a new granular activated carbon treatment system to improve water quality. The project was successfully completed using the collaborative Construction Management at Risk (CMAR) delivery method.Carollo was recognized alongside the City of Avondale EIC Engineers, and PCL Construction.

“Arizona’s visionary approach to water is creating new opportunities for civic and economic growth throughout the state,” says Jessica Dresang, Carollo’s Business Development Manager for the Southwest Region. “Through careful planning, operational efficiency, and creative solutions, Arizona’s municipalities and businesses are developing a strategic roadmap for the future of water – and the possibilities that come with it – in the state.”
