Design, Operation, and Maintenance for Sustainable Underground Storage Facilities Cover

With rising water demand, declining groundwater levels, and environmental concerns, achieving a sustainable drinking water supply has become a global priority. Managed aquifer recharge has emerged as a cost-effective solution, supported by advances in geochemistry, microbiology, and hydraulics. This project aimed to identify key factors for the successful design, operation, and maintenance of sustainable underground storage (SUS) facilities by studying both successful and failed sites. The final report highlights lessons learned, explores recharge methods, and provides practical strategies to help water utilities improve system reliability and reduce service disruptions. Additionally, case studies offer insights into how different water systems have approached underground storage to address water supply challenges.
