Schomberg Water Treatment Plant Emergency Filter Rehabilitation Project

In May 2017, the Schomberg water Treatment Plant lost filtration capacity due to unexpected failure of one of three pressure filter trains and the plant struggled to maintain system demands.  The Region replaced the filter media and retested the filters, however flows were reduced due to the limitations of the filter process to less than 50% capacity. While system demands were now satisfied, the Region considered the security of the water supply for the community to be at risk.  There was a need to increase capacity and redundancy to allow for greater optimization and ongoing maintenance. 

Temporary mobile filtration trailers were commissioned to provide the needed capacity, redundancy and water quality to complete the necessary upgrades including: replacement of  the filer media, reconfiguring the filter underdrains, replacement and optimization of the oxidation system, replacement and modification of the valves and piping, updating the instrumentation, and reprogramming of the water treatment plant process control logic.  Over the next several months, the temporary filters were carefully monitored, the existing plant filters removed from service, and upgrading and restoration of the original treatment plant began.  All upgrades were implemented in 2018 and 2019 including rigorous commissioning and site acceptance testing for more than three months. After final testing and commissioning, the plant filters were officially put back in to service in November 2019 and the temporary filters phased out by March 2020.  Eramosa provided SCADA programming services for the water treatment plant process control logic and assisted in the commissioning and testing of the upgrades.

We are very pleased to share that the Region of York’s Schomberg Water Treatment Plant Emergency Filter Rehabilitation Project has been selected as the Ontario Public Works Association’s (OPWA) 2020 Project of the Year for Emergency Construction between $2-$10 Million.  See the presentation here.

Alloa Reservoir & Pumping Station

The Alloa Reservoir and Pumping Station is located north of Mayfield Road and west of Creditview Road in the Town of Caledon. The Alloa facility will be the final reservoir and pumping station on the western transmission system, fed by the Lorne Park Water Treatment Plant, and is needed to meet imminent municipal water demands for development growth in the City of Brampton, Northwest Development Area. The Region of Peel retained Burnside for the planning, detailed design and contract administration of the Alloa Reservoir and Pumping Station project.

This facility was designed to provide an ultimate capacity of 165 ML/d. The project includes the design and construction of a 35ML, two celled reservoir with design provisions for a future expansion of the reservoir storage to 70ML; a pumping station servicing Peel Zone 6W and Zone 7W; electrical supply included twinned 750kVA transformers, 5kV switchgear, 4160V feeds to pump starters and 4160V-600/347V transformers to feed 600V MCC; 1250 kW diesel generator; provision for top-up chlorination; and a dedicated administration area with a boardroom and offices. Eramosa provided electrical, instrumentation & control and SCADA services as a sub consultant to RJ Burnside.

We are very pleased to share that the Region of Peel’s Alloa Reservoir and Pumping Station Project has been selected as the Ontario Public Works Association’s (OPWA) 2020 Project of the Year for Environmental Projects between $10-$50 Million.

CIOReview commends Eramosa’s work empowering utilities with e.RIS

As a leading magazine in the field of technology, CIOReview seeks to assist organizations in filtering through the myriad solutions in the cluttered innovation landscape. As a platform that highlights groundbreaking new methods, e.RIS is a natural fit. CIOReview selected Eramosa as one 2019’s twenty most promising utility technology solution providers. They spoke with Tim Sutherns, Eramosa’s board chair, to get his take on what makes e.RIS different and how it can spur the adoption of machine learning.

When faced with the data storm so many utilities encounter, Eramosa found a solution.

Instead of data islands, e.RIS integrates all organization data, from as many sources as necessary, into one platform. Sutherns says, “…we bridge [the] gap and bring a solution to the market to help make effective decisions.”  

Armed with the power of unified data, utilities can confidently implement cutting edge artificial intelligence tools. Working smarter, not harder, is the key to the efficient, thriving organization.

CEO Award of Merit

The 2018 Ontario Consulting Engineering Awards Award of Merit in the category of Industry, Energy + Resources was awarded to Eramosa Engineering Inc. for their collaborative work with the London Health Sciences Centre power plant and energy systems data management and visualization project.  The primary goal of the project was to re-establish integrity of the data being utilized for the energy procurement, reporting and management tasks.   Secondary goals were to automate manual data processing and house all data in one system instead of having to manually extract data from multiple systems as well as to have a near real-time reporting and data visualization tool established to allow LHSC to make better operational decisions.  LHSC retained Eramosa to develop a solution to achieve these goals.  Eramosa was presented with the award at the 16th Annual Ontario Consulting Engineering Awards Gala held on April 21, 2018.

Inductive Automation – Firebrand Award

At Inductive Automation’s Ignition Community Conference (ICC) 2017 Eramosa was presented the Gold Firebrand Award for Transformative Projects. The winning project was completed for Canadian Solar Solutions and connected numerous systems for a brighter solar future. This project involved working with Canadian Solar to create CSEye — a custom hybrid asset performance monitoring and computerized maintenance management system (CMMS) application for the solar photovoltaic (PV) operations & maintenance sector of the renewable power-generating market. CSEye is a comprehensive tool providing value to stakeholders at all levels of the Canadian Solar operations & maintenance group. Ignition provided a customizable application development environment providing full access to critical operational data from various existing SCADA architectures while allowing the project to scale as needs arose. By using Ignition Eramosa was able to solve the problem of disjointed legacy systems, providing a single application environment. The application has several benefits to the project Owner including cost-effective licensing that scales, reliable historical data feeds for near real-time analysis, modern communication protocols such as OPC-UA, Modbus, EthernetIP , Siemens Ethernet, and RESTful web services as well as standardized charting tools, UDT structures and Python scripting for database queries.

Eramosa project highlighted in magazine

A notable project that highlighted real ingenuity was recently featured in a magazine for the Ontario engineering community. The three-page article details how Eramosa partnered with the Region of Waterloo to upgrade an older SCADA system at a rural water treatment plant that is controlled remotely.

The complexities of the project were chronicled in the November/December issue of the Ontario Technologist, the Ontario Association of Certified Engineering Technicians and Technologists (OACETT) member magazine. The article was authored by Alan Couch and Franklyn Smith from the Region of Waterloo, and Jon Watson of Eramosa.
