Title: Emergency Aquifer Storage and Recovery at Sebastopol Road Well Project
Description: The Sonoma County Water Agency (Sonoma Water) is proposing a drought emergency project involving aquifer storage and recovery (ASR) at the Sebastopol Road Well Station (Well Station) to increase regional and community drought resiliency. ASR is the process of recharging the underground aquifer, when surface water is plentiful (typically during wet winter periods), for storage and use at a later time. The purpose of the project is to install ASR system components and conduct pilot testing to determine the functionality of the system to supplement water that could reduce ongoing current and future drought impacts to public water retailers (cities and water districts) and other beneficial users of groundwater within the Santa Rosa Plain Groundwater Subbasin. The project consists of installing ASR equipment at the existing Well Station, which is located along the Russian River-Cotati Intertie Aqueduct (Aqueduct), an underground pipeline. The project would retrofit an existing production well, including appurtenances and downhole well components for aquifer recharge. Surplus water from the Aqueduct would be used to test the capability of the ASR to recharge the aquifer. The proposed project would not change the designed capacity of the Well Station, Aqueduct, or impact mature trees or native vegetation.
