Responsibilities included engineering design for a 2.1 MG storage reservoir, a booster pump station, and provisions for an on-site well and an arsenic removal system for Buckeye, Arizona. DARcor is currently working on the design of the arsenic removal system. The project also included two off-site wells (Wells No.1 & 3) that delivered water to the water campus. Offsite wells were monitored and controlled by PLCs and fiber-optic infrastructure based on the water level in the storage reservoir. The water level in the reservoir was monitored using ultrasonic and submersible-type level transmitters and backup level probes for alarms.
VFD-driven booster pumps delivered water into the distribution system based on pressure demand. System pressure was monitored by two pressure transmitters with pressure switches for alarms. Two bulk storage sodium hypochlorite (NaOCl) systems were designed for disinfection.
The initial phase of the water campus included only one diesel-driven standby generator to provide backup power. However, provisions were designed to parallel up to four generators at this facility for ultimate build-out. Each offsite well included an automatic transfer switch and a diesel-driven generator.
The water campus and well sites each contain a City of Buckeye standard RTU cabinet. The RTU at the water campus was designed to be the local master RTU for the Floreo water system. A personal computer (PC) workstation was provided with AVEVA (an HMI software program) to monitor the status and alarms of the entire water system and to adjust system operating parameters.
The project is now in the construction phase, and completion is expected to occur at the end of 2026. Construction administration services will include coordination, meetings, review of submittals/shop drawings, review of O&M manuals, site inspections, I/O loop testing, and startup testing. Record drawings will also be completed at the end of construction.
