The plant is designed to meet the Arizona Department of Environmental Quality Class A+ reclaimed water quality standards and Class B solids for land application or disposal. While expanding the treatment capacities, this project also enhanced operations of the plant, including replacement, repair, and rehabilitation of aging equipment. Carollo Engineers and Brown and Caldwell served as the design engineers. Major subcontractors included Pipe Line Services dba Aims, Progressive Roofing, Harris Rebar, K&F Electric, Inc., and Schuff Steel Company, all of Phoenix, along with Prime Controls, Tempe, and Matrix Service, Tulsa, Oklahoma.

Favorite job task: I enjoy being a part of a capable, dedicated, committed, high-performing project team and encouraging my teammates to turn difficult challenges into opportunities. Toughest job task: Managing the human element of a project and ensuring no one is injured, which is also my top priority. Most memorable day at work: Bringing the Phase 3 aeration basins at Greenfield Water Reclamation Facility online for the City of Mesa in 2019. It required a complete team effort, and that was an awesome feeling! Favorite off-job task: Spending time with my family, traveling abroad (when we aren’t in a pandemic!), and woodworking. arizcc.com
