Conventional geothermal systems can post certain challenges with respect to installation costs, space constraints and availability of labor. Water-based systems only need a sink and source and that could come from unconventional sources. This session highlights projects and the potential to cost effectively reclaim energy from waste water. Speakers exchange first-hand experiences to reclaim energy from black and grey water, abandoned mines, reclaimed municipal water and retention pond with treated wastewater.
