Note: Review Per Lead
LADWP proposes to implement the De Soto Trunk Line Replacement Project to increase the safety, capacity, and reliability of the city of Los Angeles potable water supply in the western San Fernando Valley area. The proposed project would replace portions of the existing De Soto Trunk Line, Roscoe Trunk Line, Canoga Topham Trunk Line, and Ventura Trunk Line that are aging, deteriorating, and nearing the end of their service life. The existing pipelines range from 30 in to 52 in in diameter and will be replaced with 54-in and 42-in diameter welded steel pipe. The proposed project would also include installation of maintenance/access holes, isolation valves, blow-offs, air/vacuum valves, and flowmeters that are required for the operation, monitoring, and maintenance of the trunk lines.
