Resilient Energy for Wastewater Infrastructure Grant Program
The Resilient Energy for Wastewater Infrastructure (REWI) Grant Program funds the implementation of solar energy and battery storage at publicly owned wastewater treatment plants (WWTPs). Wastewater infrastructure is vital for maintaining public health, environmental safety, economic stability and overall community functionality. Traditionally designed for reliability, these systems encounter new stressors from hazardous weather, aging assets, cyber threats, and population changes. Investing in resilient infrastructure not only extends the life of wastewater facilities but also reduces operational costs and enhances community well-being, especially during severe weather events. Key benefits include minimizing service disruptions, managing risks more effectively, and creating more cohesive system-wide planning strategies.
The REWI Grant Program is funded by the U.S. Department of Energy (USDOE) State Energy Program (SEP) from supplemental appropriations authorized under the Infrastructure Investment and Jobs Act (IIJA).
