Document Description
DWR San Joaquin Field Division performs yearly maintenance to the SWP. This requires that specific portions of the California Aqueduct (CAAQ) coastal branch be shut down and emptied of all water, so that SJFD personnel can safely perform the various maintenance activities (electrical, mechanical, corrosion protection, inspection). This work, known as the 2018 Coastal Outage, will require the dewatering of the Polonio Pass Pumping Plant forebay, Vault 26.99, and Vault 27.47. Water from all 3 sites will be discharged into an adjacent natural drainage. The 2018 Coastal Outage will begin on October 29, 2018 and end November 21, 2018. However, dewatering activities will begin Oct 15, 2018 and will take approx 10-14 days to complete.
