Arizona water and wastewater utilities depend on SCADA and PLC systems to run treatment, pumping, distribution, and collection around the clock. Canfield Engineering & Integration is an Arizona-based EI&C firm that designs, programs, commissions, and supports those control systems — so operators get reliable automation and clear visibility into every site.

Why Arizona utilities need a specialized controls integrator

Water systems here span long distances, remote well fields, and booster and lift stations that have to run unattended. Many are still operating on aging RTUs or unsupported PLC platforms, and federal requirements under America’s Water Infrastructure Act (AWIA) have raised the bar on OT cybersecurity and resilience. A controls partner who understands both the process and the plant floor keeps those systems safe, current, and maintainable.
