Halton Region has population of 500,000 with three (3) lake-based and three (3) well-based water treatment plants. In 2012, the water treatment system produced 66,803,132 cubic meters (66.6 billion litres / 17.6 billion gallons) of treated water.
Managing every system and subsystem is a large task faced by all water utilities. In Halton Region, there are thousands of process data values recorded every minute and logged to two Wonderware Historians. Traditionally, custom programs are written to extract specific data from these historians to produce daily and yearly reports for each process. The programing used in these reports is very process specific and not easily transferable between plants.
In 2006, Halton Region partnered with Eramosa to transform its reporting from Microsoft Excel-based reports to the Eramosa Reporting and Information System (e.RIS). This centralized, web-based reporting system provides many advantages over Excel-based reporting including Active Directory user authentication, report distribution user groups, and an easy-to-use report builder. Since 2006, use of e.RIS has increased to over 100 users in Halton Region. Many of the requests for historical data that were traditionally handled by the SCADA department have been eliminated due to the accessibility of the data from the web page interface. Requests that were taking weeks are now being done in minutes by the stakeholder without requiring outside assistance. The e.RIS reporting software enables users to create and maintain their own reports. The system can be configured to automatically generate and then share these reports to specified users. Connections to many different data sources are managed by the reporting software and exposed to the reporting environment as a simple list of tags.
Critical Alarm Response
Eramosa worked with Halton Region to implement an alarm monitoring, regulatory reporting, and response tool. Critical alarms were identified and reprioritized to enable both an ordered alarm hierarchy and filtering functionality. Each of the alarms identified as critical to system operations have been linked directly to Halton Work Instructions (a repository of SOP Manuals) in the SCADA HMI using SharePoint Services. A web-based e.RIS commenting tool was also implemented to enable commenting of each critical alarm occurrence. Alarms and the associated comments are included in the reports which can then be electronically signed by operators to provide evidence of the corrective action taken.
