Document Description
The Metropolitan Water District of Southern California (Metropolitan) proposes to rehabilitate 18 expansion joints at the Hinds Pumping Pumping. The 18 expansion and contraction of the Plant's discharge pipelines, as a result of temperature changes. All of the expansion joints have been in continuous service for over 50 years. In order to maintain reliable Colorador River Aqueduct (CRA) deliveries, the joints need to be rehabilitated. Due to the time required for curing of the specialized coatings and the constrained shutdown window for the CRA, repair of the joints has been staged to take place over two shutdown seasons. The Stage 1 repairs will address the nine expansion joints located on there 6-foot diameter pipelines during a February 2012 shutdown. The remaining nine expansion joints on three 10-foot diameter discharge lines are planned to be repaired during the next CRA shutdown in 2013.
