An Ottawa city committee is looking at a proposed plan to use municipal wastewater to help heat and cool apartment buildings at the future LeBreton Flats development without the use of fossil fuels.
A report prepared for the Environment and Climate Change Committee delves into the possibility of using a "wastewater energy transfer" or WET system to extract heat generated by wastewater and convert it to energy to aid in its goal of building a net-zero carbon development.
A similar technology is in use at the Zibi site, using heat generated by the Kruger plant in Gatineau and water from the Ottawa River to provide heating and cooling.
