EBMUD replaced the South Reservoir, located at the north end of Gail Drive near Grove Way in Castro Valley, with a 9-million-gallon water storage tank within the footprint of the existing reservoir basin in January 2020. The reservoir replacement project improves water quality and increases reliability in the distribution system. The new reservoir was designed to meet current seismic design standards. No significant change was made to the views of the reservoir from surrounding residences as a result of this project, and most of the existing embankment slopes remained in place. Additional landscape screening was planted along the western and southeast edges of the reservoir site perimeter to enhance the existing screening of views of the new tank for residents along Grove Way and Gail Drive.
