IT infrastructure is the heart of the control system used for automated monitoring and control of critical infrastructure, including wastewater systems. Advances in IT components and implementation approaches can be applied to provide faster, more reliable control systems with better access to integrated enterprise data to help engineering, planning, and O&M staff better understand and manage their facilities. Correct application requires thoughtful planning and regular upgrade to keep the system functional and reliable.
The City and its contract operations partner, Jacobs, are nearing completion of a major Supervisory Control and Data Acquisition (SCADA) system upgrade of the City’s two Wastewater Treatment Plants. The SCADA upgrade included complete redesign of the IT systems at the City’s Wastewater facilities, which has reduced major risk and provided significant value to the City.
The new core network and computer equipment includes virtualized servers with automated backups to reduce physical space and facilitate disaster recovery, ring networks for improved reliability, a DMZ for protected access of shared system data, updated computer hardware with current operating systems and software to accommodate supportability and reliability, and new fiber optic cable infrastructure. The project will also network-connect large Variable Frequency Drive motors for monitoring of voltage and current, and remote resetting of drive failures. The SCADA system will be linked to the computerized maintenance management system to allow work orders to be automatically triggered based on equipment alarms or runtimes from the SCADA system.
Operators can now monitor and control the entire wastewater system from workstations at either treatment plant or from any remote station. Jacobs support staff provide troubleshooting and maintenance via secure remote access, and are notified of problems in real time to provide faster response.
This presentation will include video interviews with plant staff describing what has changed, current operational practices and lessons learned.
