The first-ever analysis of resource recovery by U.S. water utilities shows significant progress in using biosolids and generating energy, but large growth opportunities in water reuse and nutrient capture.
Led by the Water Environment Federation, the ReNEW Water Project utilizes data from national and state databases, publications, and a utility survey, which represents about 25 percent of municipal wastewater flow and about 20 percent of biosolids produced in the U.S.
“With each passing year, more water utilities are engaging in resource recovery both for the environmental benefits and the economic opportunities that emerge,” said Eileen O’Neill, Executive Director of WEF. “Establishing metrics on resource recovery is crucial to moving into a more circular economy that ensures sustainability for future generations. WEF is proud to launch the ReNEW Water Project to monitor and accelerate the rate of water reuse, nutrient capture, and energy generation by facilities.”
The data showed the following levels of recovery of available resources:
WEF launched the ReNEW Water Project to create a bold, aspirational, and public call to action to accelerate resource recovery. The NEW stands for nutrients, energy, and water. The first step was establishing the baseline for current resource recovery practices. Later this fall, WEF will announce goals for water utilities to increase resource recovery from baseline levels. New data will be collected on a biannual basis and expanded to Canadian water facilities.
Aging infrastructure, population pressures, climate change, and funding limitations strain water resources and call for sustainable management solutions. Wastewater treatment plants cannot operate merely as disposal facilities any longer. Instead, resource recovery must become a cornerstone of facility operation, producing water for reuse, recovering nutrients, and reducing fossil fuel consumption by using the energy in wastewater. To help guide utilities and sector decisionmakers, WEF offers Resource Recovery Roadmaps.
Supporting organizations for the ReNEW Water Project include the Association of Clean Water Administrators (ACWA), National Association of Clean Water Agencies (NACWA), The Water Research Foundation (WRF), and WateReuse Association, as well as Réseau Environnement in Quebec.
The Water Environment Federation (WEF) is a not-for-profit technical and educational organization of 35,000 individual members and 75 affiliated Member Associations representing water quality professionals around the world. Since 1928, WEF and its members have protected public health and the environment. As a global water sector leader, our mission is to connect water professionals, enrich the expertise of water professionals, increase the awareness of the importance of water, and provide a platform for water sector innovation.
