The City of Reedley, California, Public Works Department is responsible for facilities that provide services for water distribution, stormwater collection, wastewater collection and treatment, and solids disposal systems throughout the City’s sphere of influence. The various systems have been operated independently with different types of SCADA hardware and software.

The primary purpose of the master plan was to determine the most economical way of consolidating, integrating, and standardizing all of the various water, stormwater, and wastewater related SCADA facilities to enable City staff to manage the system more efficiently with less burden on operations staff.

Carollo was retained to perform an evaluation of these facilities. We prepared a SCADA Master Plan that provided the necessary information to design a functional and consolidated control system for the City’s various utilities departments. The goal was to develop a control system master plan that would reduce the utilities’ current operating costs by replacing existing obsolete equipment, improving operational efficiency through utilization of
innovative technologies, improving current operations staff efficiency, reducing total chemical usage, and reducing total electrical power consumption.

The wastewater treatment plant is currently undergoing an expansion that will include a new SCADA system, which will serve as the central consolidation point as well as a foundation for the new citywide SCADA system project. Carollo is programming the new wastewater treatment
plant SCADA system, which uses a Wonderware InTouch HMI and Modicon Quantum PLCs.
