SCADA System Assessment
The City of Norwalk has water operations located across three different regions and, as a result, was facing challenges with cost-effective water operations. In many cases, the City had to accept external sources of water due to limitations in the existing system. To better control costs and streamline water operations, the City made improvements in their water pipeline and water SCADA system infrastructure. The first step to implementing a new City-wide SCADA system was to evaluate the existing infrastructure, identify required changes to achieve the improved automation and operation of the system, and develop a plan to integrate each site into one common SCADA system platform.
Cannon was selected to provide a SCADA Assessment for the City that targeted a system with limited existing SCADA infrastructure. We conducted site assessments; provided radio path surveys at each of the 28 site locations; and evaluated field instrumentation, control system functionality, and telemetry across the City. As part of this evaluation, Cannon objectively assessed PLC and HMI vendor solutions based on City functional needs and life-cycle costs. Additionally, we evaluated multiple telemetry solutions and provided a recommendation for the best telemetry solution heading into the future.
