@begiantca: What if your home was heated by human sewage? Every time someone runs a tap, dishwasher, washing machine, or yes, even flushes the toilet we're sending heat straight down the drain, so why not use it? In Vancouver, the under- construction Sen̓áḵw development project by the Squamish Nation will tap into a nearby sewer line to provide carbon-free heating and cooling for about 6,000 residents. While the heat generated by sewage is a simple byproduct of waste, the process was anything but straightforward. It required drilling into an active, highly pressurized main, all without interrupting municipal services. Such systems are not cheap: Sen̓áḵw’s $30-million district energy system represents a substantial investment, but it’s designed to yield long-term benefits. With most of the progress happening out of the public eye, the scale of potential is easy to miss. One of Canada’s biggest wastewater energy-transfer systems, in fact, has quietly taken shape beneath University Health Network’s (UHN) Toronto Western Hospital. Even though the upfront costs of waste and sewage heat recovery remain substantial, the potential for cheaper energy once installed – and zero-carbon energy at that – could be well worth it. 🚽🚿🚰 #cleanenergy #SustainableEnergy #Sustainability
