This session is of utmost importance as it tackles critical queries and issues related to energy resilience and sustainability in the face of climate change. It addresses the urgent matter of ensuring continuous access to essential heating, cooling, and enabling domestic hot water production, especially in situations involving grid disruptions. At this moment in time, with the increasing frequency of extreme weather events and the pressing need to reduce carbon emissions, the resilience of our energy systems is paramount. The session focuses on an inventive approach, where Wastewater Energy Transfer (WET) technology leverages existing sanitary infrastructure to provide thermal energy solutions. This session directly aligns with the conference theme of "Climate Resilience" by presenting a tangible solution that not only enhances energy efficiency but also bolsters climate resilience. It addresses the need to adapt and thrive in an era of climate uncertainty. By harnessing the sustainable potential of WET technology, we can strengthen our communities and infrastructure against the challenges posed by climate change.
