Western Canadian municipalities are turning to solar to power water and wastewater treatment plants (WWTP) as a means to decarbonize and cut costs. The trend is particularly strong in sunny Alberta and Saskatchewan, where electricity is traditionally produced by natural gas or coal. Lumsden, a Saskatchewan town with a population of 1,800, turned to solar when its outdated lagoon system near a river meant stepping up to a mechanical WWTP.
Biodigesters transform food waste into water
Food waste at CFB Esquimalt’s galleys, once scraped into green bins and hauled to the landfill, is now being decomposed on site. Two Power Knot LFC biodigesters installed at Nelles Block Galley decompose biodegradable garbage and turn it into grey water. Two more will be installed at Work Point’s Venture Galley as part of the base’s green initiative. “Anything that can protect our environment, reduce our carbon footprint and CO2 emissions, and cut costs at the same time is a great initiative,” says PO2 David Keneford, Nelles Block Galley Manager.
