Title

Emergency Sebastopol Road Well Activation Project

Description

The Sonoma County Water Agency (Sonoma Water) is proposing a drought emergency project to bring an existing groundwater well at the Sebastopol Road Well Station (Well Station) into operation and to increase regional and community drought resiliency. The Well Station is located along the Russian River-Cotati Intertie Aqueduct (underground pipeline). The purpose of the project is to provide supplemental water from the existing well to support agriculture and public water retailers (cities and water districts) during the drought emergency. The project will consist of installing additional piping and associated equipment from the well to the underground pipeline to ensure chlorine contact time regulatory requirements are met for potable water use. The new piping and appurtenances would be installed primarily beneath the existing graveled hardscape and disturbed areas adjacent to the Aqueduct and well. Approximately 250 feet of 36-inch-diameter pipe would be installed. In addition, a discharge pipe would be installed from two new holding tanks to a permanent connection to the existing underground recycled pipeline located approximately 15 feet from the Well Station fence line. The holding tanks are primarily used for chlorine analyzer discharge and well operations flush water, which will be de-chlorinated prior to discharge to the underground recycled pipeline. Project activities would be contained within the 0.13-acre work area and 0.12-acre staging area. All disturbed areas would be returned to pre-existing conditions. The proposed project would not change the existing capacity of the Aqueduct or impact mature trees or native vegetation.
