BACKGROUND & HISTORY:
The Utilities Department (UD) is responsible for the operation and upkeep of a wide range of facilities that support the City of Corona's water, wastewater, and reclaimed water systems. These include 4 water treatment plants, 24 well sites, 18 booster stations, 19 water storage tanks, 46 pressure-reducing stations, 3 wastewater treatment plants, 14 sewer lift stations, and 3 reclaimed water booster stations. These facilities are vital to ensuring the efficient and continuous delivery of water and wastewater services to the City’s residents and businesses.
Motor Control Centers (MCCs) are essential components within these facilities. They serve as the nerve centers for controlling and managing the operation of key equipment such as pumps, motors, and blowers. MCCs regulate the electrical flow to these devices, enabling the proper functioning of critical processes that maintain the City's water and wastewater systems. As the central control point for equipment, MCCs ensure efficient, reliable, and safe operations.
As part of the ongoing efforts to maintain system reliability and efficiency, UD has identified the need to replace and upgrade aging MCCs that have surpassed their useful life at several key locations. These upgrades are essential for minimizing downtime, improving the operational performance of critical infrastructure, and maintaining compliance with City standards.
This Professional Services Agreement with Albert A. Webb (Webb) Associates, Inc. will provide the necessary engineering design, project management, and technical support services to complete the MCC replacements and upgrades, ensuring the continued reliability of the City's infrastructure.
