Document Description
The Project involves the rehabilitation and repair of aging mechanical equipment and appurtenant components and structures related to the outlet works at Cogswell Dam. The Project includes work at three butterfly valves and one sluice gate, including rehabilitation and repair of the valve and gate bodies and seals, hydraulic cylinder actuators, outlet conduits, and trashracks. This work would minimize leakage through the valves to reduce water conservation losses from Cogswell Reservoir and extend the service life of the outlet valves, sluice gate, and appurtenant structures to ensure the continued flood control and water conservation operations of Cogswell Dam for the benefit of downstream communities.
