Tetra Tech Digital Systems modernized the City of Fresno’s SCADA, network, and reporting platforms to improve cybersecurity, accelerate operations, and streamline required water production reporting.
The City of Fresno Water Division needed to address pending loss of product support and reporting system pain points while maintaining cybersecurity, SCADA functionality, and required water production reporting. The division operates a drinking water system serving approximately 142,000 residential, commercial, and industrial customers across 114 square miles. End users of the legacy reporting software requested a more effective way to maintain, update, and publish reports.
We performed systemwide platform upgrades, updated the network architecture, and overhauled reporting infrastructure. We also upgraded the SCADA system to the newest version, retained key functionality, added tools, and addressed operator issues with the legacy system. The upgrades accelerated weekly tag and equipment updates and reduced AVEVA Plant SCADA startup time by more than 66 percent.
Our team implemented network segmentation across 17 networks using local area networks (LAN) and firewalls, enabling selective, controlled communication and prioritizing critical programmable logic controller (PLC) traffic. We replaced the legacy reporting system with AVEVA Reports for Operations and SQL Server Reporting Services (SSRS) to automate report generation, sending, and organization. We also set up AVEVA Tier 1 and Tier 2 Historian to consolidate data from current and future plants, providing customized reporting options that narrow priority objects and show status at a glance.
Benefits
- Reduced AVEVA Plant SCADA startup time by more than 66 percent
- Segmented 17 networks using LANs and firewalls
