This project includes rehabilitation and seismic work on Sutro reservoir. Under this project the reservoir will be upgraded to meet current seismic standards and conform to all State Health requirements. Reservoir circulation problems will be corrected with the construction of separate inlet and outlet structures. The results of physical modeling studies will be used to orient the inlet and outlet pipelines and structures. Other work to be carried out will include: embankment and erosion work; inlet piping; concrete repair on the interior soffit, beams, columns, cleaning the reservoir, disposal of sediment and final cleaning; repairing the liner; seal cold joints, coat and repair the roof concrete, new inlet structures with buried concrete vaults and automated valves; new expansion joints; block off perimeter vents; installing a new access hatch; new perimeter security fencing; liner repair; new locking systems on reservoir doors; sampling and disinfection facilities; tree removal; perimeter path repaving; hazardous soil management; and seismic upgrade.
