Partner Spotlight – Red Deer Wastewater

Background

The City of Red Deer Wastewater Treatment Plant receives sewage from the City of Red Deer, the Towns of Penhold and Springbrook, the Red Deer Airport, and Gasoline Alley on the outskirts of Red Deer. With the current upgrade complete, the plant process design capacity increased from 47,500 to 72,500 cubic metres of wastewater per day. The upgrades included two (2) Fat, Oils, Grease (FOG) stations, two (2) vendor package septage receiving stations, and two (2) vendor package dewatering system units. In addition to the plant expansion, improvements occurred to digester heating, mixing, and biogas production to generate power and heating to be utilized within the plant. Also, an equalization pump house was upgraded which is used during high flows and/or shutdown events where the excess flows are bypassed into lagoons.

Integration

Originally the plant utilized a Microsoft Excel macro to meet their regulatory reporting requirements to Alberta Environment and Parks. This was accessible at the new administrator building. 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. As part of the SCADA upgrade, the old reporting server was replaced with an e.RIS server. The upgrade involved the installation of two (2) SCADA servers that act as the primary and secondary database, one (1) terminal server, and one (1) historian server with Microsoft SQL Server with the existing historian files being migrated into it. The plant Laboratory Information Management System (LIMS) database was also integrated to further reporting capabilities.

Existing reports were kept for consistency and migrated for use in e.RIS. As a result of the plant expansion, a few reports have been added targeting the addition of two (2) primary and three (3) secondary clarifiers, one (1) fermenter, and two (2) trains bioreactor. Annual influent and effluent analysis, annual fermenter volatile fatty acid analysis, monthly influent and effluent flows, digester analysis, boiler analysis, polymer and chlorine chemical flows, bioreactor reports are column-based reports. Calculations and data manipulations were also implemented for annual effluent flows and bioreactor daily influent reports.

Innovative Collaboration

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. Operators can input manual data entry values for the draining lagoon, sludge depth, and settling. With advanced calculations and data manipulation for bioreactor influent and plant effluent, the amount of sewage being treated is monitored and controlled.

The reporting tool has been a significant resource for process analysis, process optimization, and further decision making to meet regulatory requirements. The City recognizes the tremendous benefits and future opportunities that e.RIS provides.
