Document Description
The Weymouth Plant Finished Water Reservoir has three inlet gates, three bypass gates and three outlet gates. All nine gates were originally installed in 1964. Properly functioning gates are required to isolate the reservoir when it is removed from service for maintenance. During routine inspection, the Metropolitan Water District of Southern California detected corrosion of both the gate and its guide at Inlet Gate #2. Metropolitan is proposing to remove Inlet Gate #2 and its operator assembly during a planned Weymouth Plant shutdown and installing a steel drop gate at the same location. Metropolitan is also proposing the in-place inspection of the other eight normally submerged gates during the upcoming Plant shutdown. Based on this inspection, Metropolitan will determine the need for refurbishment or replacement of the remaining gates.
