The water treatment plant was built in the 1980s to supply safe drinking water to the City of Fort McMurray in the Regional Municipality of Wood Buffalo in northern Alberta. With various upgrades to plant production, capacity has increased from 52 ML/d to 104 ML/d. From 2011 to 2013, upgrades were completed including the expansion of the pre-treatment, filtration, and primary disinfection areas as well as an expansion of the on-site treated water storage. The raw water intake station draws water from the Athabasca River into the intake ponds to settle the solids. From each pond, which is hydraulically connected to the transfer station, the raw water is transferred to the dual cross clarifier, followed by the Actiflo high rate clarifier, and then onto eight (8) media filters. The filtered water is pumped to the UV disinfection system and then onto the clear well, which feeds the high lift station for distribution to the Municipality.
Eramosa partnered with the City to address the monitoring and reporting requirements of its water systems. Originally the plant utilized a Microsoft Excel macro to meet their regulatory reporting requirements to Alberta Environment and Parks. The plant used a Proficy historian to gather data for historical data monitoring and retrieval. The collected data was then translated to the Excel reporting system.
The City chose the Eramosa Reporting and Information System (e.RIS) to replace the current system and utilized Eramosa’s industry knowledge to create a cost-effective implementation. Moving to the e.RIS system included hardware and software changes. Under the recent plant upgrades, installation of two (2) SCADA servers that acts as the primary and secondary database, one (1) terminal server, and one (1) historian server with Microsoft SQL Server was deployed. The e.RIS server was installed in 2015 for the reporting needs of the Municipality.
As a result of the plant upgrade and expansion, many new reports have been generated such as the daily operational report, daily and monthly flows, contact time hourly and monthly compliance, annual raw and distributed water volume, filtered and treated water turbidity, monthly ultraviolet reactor, high lift discharge pressure, ultraviolet transmittance, chemical consumption, chemical suppliers, and the annual report which includes various process data calculations and manipulations within the plant.
The benefits of having e.RIS are the capacity to manage and analyze various data and its accessibility. The plant operator or administrator can open e.RIS on every SCADA node across the plant. Each SCADA node is using terminal server technology, via the remote desktop protocol, to access a web browser to log into e.RIS. The e.RIS capability to store iFIX alarms and have it embedded into the plant’s iFIX HMI is useful to easily navigate and filter alarms. The alarm patterns are also used to track chemical dosage alarms.
The contact time compliance report is vital for the plant process operation. Making sure the contact time value is compliant is an important part of calculating disinfectant dosages when chlorinating drinking water to achieve the desired removal of microorganisms. With the contact time reports, the Contact Time Performance Ratio can be evaluated and analyzed with respect to the chlorine residual.
The reporting tool has been a significant resource for process analysis, process optimization, and further decision making to meet regulatory requirements. The Municipality recognizes the tremendous benefits and future opportunities that e.RIS provides.
