WCWC launched a new remote monitoring system. Geordie Gauld, Technician, tells us more about how the new system will assist with pilot testing projects to support water system owners, operators and operating authorities.
What exactly is the new remote monitoring system? How does it work?
Essentially, this is a small-scale Supervisory Control and Data Acquisition (SCADA) system with cellular connectivity. It operates on many of the same principles as the monitoring and control system at a full-scale water treatment facility. A simple programmable logic controller (PLC) will take in process signals from the pilot plant, including parameters like water pressure, flow, turbidity, pH, etc. Using these inputs, we can observe system statuses, compile datasets, and generate historical trends from right here at WCWC.
How will this benefit pilot testing projects?
It can be challenging to gather complete data from our pilot testing communities. Many are in remote regions and we cannot stay onsite for weeks to manually gather data. Operators are also very busy running their own facilities and don’t have the time to manually sample and collect the data we need and get it into our hands. This system will allow us to collect complete datasets with little to no input from operators. Complete data will lead to a more effective pilot testing process and allow WCWC and the facility owner to make more informed decisions regarding the direction of the pilot testing project, no matter where the owner’s plant is located.
Being able to view the status of the system in real-time will also allow us to confirm things are running as they should be. An undetected failure in the pilot plant can render large sets of data incomplete or inaccurate and delay the overall progress of the pilot testing project.
How is one monitoring system going to be effective for multiple pilot testing projects that may have many different requirements?
By reviewing the configurations of previous pilot testing projects, we were able to compile a list of modular hardware requirements we felt would be most useful. This allowed us to wire and pre-program the unit for common configurations with the ability to use or omit certain features as desired. This approach will allow us a great deal of flexibility working with different treatment strategies and arrangements. In our hardware selection we also allowed for several “spare” inputs which will allow us to expand our capabilities in the future.

The Walkerton Clean Water Centre (WCWC) recently completed a pilot testing project with the Township of Tay to address seasonal taste and odour events.
The community has been experiencing seasonal taste and odour events, such as geosmin and methyl-isoborneol (MIB) in the raw and treated water. The community’s ultrafilter effluent was used to test an advanced oxidation process (AOP) (high UV dose + hydrogen peroxide) and granular activated carbon (GAC) to reduce taste and odour compounds. WCWC confirmed that both AOP and GAC removed the taste and odour compounds to below the odour threshold; however, additional chlorine was needed after the AOP process. The township and engineering consultant will use the results to select the appropriate treatment for their system upgrades.
WCWC conducts pilot tests for clients to enhance their understanding of source water characteristics and the performance of treatment processes and alternative treatment options. Bench or pilot scale projects can be undertaken at a client’s location or at the Technology Demonstration Facility in Walkerton.
WCWC has years of pilot testing experience in areas such as natural organic matter, disinfection by-products, iron and manganese treatment, arsenic, and coagulation. Pilot testing reports are available on WCWC’s Drinking Water Resource Library at www.DrinkingWaterResourceLibrary.ca, which is a free online portal that assists drinking water professionals find information on various topics.
