The Challenge: Public water supplies in the United States come from a variety of sources (such as groundwater and surface water), but factors like population growth and extended droughts are stressing these supplies in some regions.  Consequently, new strategies are needed to help meet future water demands and develop more sustainable water supplies.  One such strategy is DPR, in which treated wastewater is used to augment public water supplies. 


How the Environmental Community Fits In: The environmental community supports the development of safe, reliable, and cost-effective water supply projects; however, they need more information to better understand DPR’s role as a potential sustainable source of water supply and to support the implementation of DPR projects.  At present, few resources exist that are designed to specifically address the environmental community’s interest in sustainable communities and their role in advancing DPR.  


This workshop will help bridge the gap between the scientific community (academic researchers), the engineering community (water treatment and supply agencies), the environmental community (nonprofit organizations), and policymakers (state regulators, etc.).
