Storing Water Today for Tomorrow’s Needs
Two new groundwater wells in Roseville are expanding the City’s ability to store water in wet periods and use it when conditions turn dry.
The Misty Wood and Campus Oaks wells in Central/West Roseville are part of Roseville’s Aquifer Storage and Recovery (ASR) program—an approach that strengthens water supply reliability by managing water underground.
These wells are designed to do two things: store excess surface water when it is available and pump it back out during drought conditions. By shifting when and how water is used, the system helps reduce reliance on Folsom Reservoir during dry periods while maintaining a consistent supply for the community.
Construction on both wells began in 2023, starting with drilling deep into the aquifer, which has the potential to store twice the volume of water as Folsom Reservoir. Work is continuing through 2026 to complete the above-ground facilities, connect the wells to the system, and bring them online.
Once complete, the Misty Wood and Campus Oaks wells will expand Roseville’s ASR system from seven to nine wells—part of a long-term effort to build a more flexible and reliable water supply.
This approach builds on lessons from past droughts, when water levels in Folsom Reservoir dropped significantly. In response, Roseville has continued to invest in a broader mix of water sources, including groundwater storage, to better manage changing conditions.
The ASR program allows the City to coordinate surface water and groundwater use—capturing water when it is plentiful and saving it for when it is needed most. This not only supports water reliability in Roseville and beyond, but also helps protect flows in the Lower American River during critical periods.
Together, these investments reflect a long-term strategy: use available water more efficiently, plan for variability, and build a system that can respond to both wet and dry years.
