We are a 501(c) 3 Research Foundation started in 1989 to address
research needs of the wastewater industry. We fund and manage
research projects to produce actionable results for our subscribers.
Need
Drinking water and wastewater systems account for approximately 3 percent of energy use in the United States; however, for municipal governments, drinking water and wastewater plants are typically the largest energy consumers, accounting for 30 percent of total energy consumed.

Energy – Production and Efficiency

Objective:
Provide research to develop new approaches that
will allow wastewater treatment plants to be energy
neutral, and thus able to operate solely on the
energy embedded in the water and wastes they
treat.

Energy Reduction and Production Opportunities, Case Studies of Energy-Neutral Wastewater Facilities and Triple Bottom Line Planning. This is a 2-year project co-funded by the New York State Energy Research and Development Authority (NYSERDA). Low Energy Treatment Alternatives to Activated Sludge Processes. This is a collaboration with the WateReuse Research Foundation for a series of four initial concept studies investigating emerging technologies for wastewater treatment that have the potential to be low energy alternatives to activated sludge processes. Anaerobic Membrane Bioreactors for Sustainable Wastewater Treatment-LCC/LCA Evaluation. A 2-year project to determine the potential for anaerobia membrane bioreactors to provide a sustainable low-energy treatment alternative at low (15 C) operating temperatures. Green Energy Life Cycle Assessment Tool (GELCAT): Version 2. A cooperative project leave by the Water Research Foundation. WERF’s GELCAT tool (developed in 2011) will be expanded to add micro-hydro energy and thermal energy recovery applications to the original solar, wind and hydro power applications.
