With the need to provide cost-effective distribution and remote facility monitoring, the Ontario Clean Water Agency (OCWA) has invested in sophisticated Telemetry, Control, and Data Acquisition systems. OCWA's first water service zone to undergo a complete instrumentation upgrade is the Lake Huron Water Supply System. The service area extends over twenty-five hundred square kilometers, including an 85 MGD (320,000 m3/day) water treatment plant and several small sewage treatment facilities, pumping stations, reservoirs, and valve chambers. The initial attempt at the upgrade resulted in a system that failed to address the needs of the facility. After reexamining these needs, OCWA hired a systems integrator to address the deficiencies. The system provides real time control, data acquisition, and operating statistics for the previous five years (by way of a client-server based historian). The historian will record on-line information, laboratory results, maintenance reports, etc. This information is automatically tabulated into various electronic reports, reducing the number of paper reports generated. Commissioning for the control portion of the revised system was completed in early 1995. This paper focuses on the difficulty experienced during development of the control system, and how limitations have been overcome. Also presented are the benefits derived from the control system.
