SCADA Systems Technologist, Wastewater

JOB SUMMARY

The Wastewater Treatment Branch manages the operation and maintenance of the major City wastewater treatment facility and various communal treatment systems, provides technical expertise for wastewater treatment process technologies, and is responsible to protect public health by ensuring all environmental compliances and preventive and corrective maintenance are performed as required.  The Wastewater Collection Branch is responsible for the operation and maintenance of the City’s Wastewater Collection infrastructure and systems including communal wastewater treatment facilities and wastewater system, and oversees the Sewer Use Program.    

You are responsible for technical support for the day-to-day delivery of the Supervisory Control and Data Acquisition (SCADA)* system for Wastewater Services, which enables the monitoring, operation and control of all City-wide wastewater collection and treatment processes, and related equipment, linear assets, remote facilities and plant.

This includes responsibility for: designing, developing and implementing complete SCADA systems in Wastewater Services; maintaining the SCADA infrastructure to enable the monitoring, operation and control of all City-wide wastewater collection and treatment processes; administering and ensuring security of the SCADA systems/infrastructure; troubleshooting, diagnosing, and resolving SCADA system malfunctions; and acting as a SCADA technical expert. 

*The SCADA system and its entire infrastructure are totally independent of City IT operations since it is a unique industrial system, comprising both legacy and “smart” hardware and software.  The SCADA system includes several components: the  human–machine interfaces (HMI’s), which are the terminals/screens which present process data to human operators, so they can monitor and control the processes; the computer control systems, which gather (acquire) data on the processes, continuously update databases, and send commands (control) to the processes; programmable logic controllers  (PLCs) which connect to sensors in the numerous processes (in the hundreds of sewage pipes, pumping stations, tanks etc. throughout the City), convert sensor signals to digital data, and send digital data to the supervisory system; the communication infrastructure (entire network) which connects the hundreds of PLCs to the computer control systems (comprising servers, WAN, LAN, fibre optics/telecom/satellite and other connections, with switches, routers, firewalls etc.); and  various process and analytical instrumentation.

EDUCATION AND EXPERIENCE

Completion of 3 year community college diploma in Electronics Engineering, Electrical Engineering, Control Systems or a related field
