Summary
The Region of Waterloo is reducing its environment footprint with a project intended to decrease electrical costs at its three largest wastewater treatment plants.
While the complications created by the global pandemic have set the construction timetable back by four to six months, a $24.1-million project to install cogeneration units at the Kitchener, Galt, and Waterloo plants is now in its final stages, with commissioning expected in the next few months.
Jacobs Engineering Group is the consultant overseeing the design and construction of the systems and W.A. Stephenson Mechanical Contractors Ltd. is the general contractor.
Comprised of pre-fabricated combined heat and power (CHP) engines, air, gas, and selective catalytic reduction systems, switchgear, and other components supplied by European and American manufacturers, the units will be fueled by biogas, a waste product expelled during the treatment process, says the region’s manager of engineering and wastewater programs, Trevor Brown.
The gas conditioning systems will remove compounds from the biogas, like moisture and chemicals, to help prevent premature wear and tear on the engines, he says.
Although some connections are still required, an 800 kilowatt engine has been installed in Kitchener, which is the Region’s largest wastewater treatment plant, with 600 kilowatt engines each at Galt and Waterloo. The engines and supporting equipment are housed within noise-dampening containers, while onsite assembly was required for the gas conditioning systems.
