The Balboa Boulevard Earthquake Resistant Pipeline Replacement Project will replace approximately one mile of existing 12-inch water mainline first installed in 1932 with 12-inch earthquake resistant ductile iron pipe.

In 2015, the Chatsworth Ecology Pond (Pond) was drying up and LADWP sought sustainable solutions to keep water in the Pond without using potable water

The Corbin Avenue Mainline Replacement Project is an important part of LADWP’s plan to replace aging infrastructure, in alliance with LADWP’s Water Infrastructure Plan to promote long-term efficient operation and lower the risk of disruptions due to pipeline failures.

The existing 6-inch cast-iron mainline is over 60-years old and will be replaced with a more substantial 12-inch, earthquake resilient ductile iron pipe on a one-mile stretch of De Soto Avenue from Nordhoff to Bryant.

The De Soto Reservoir was placed into service in 1941 and is a Los Angeles Department of Water and Power (LADWP) drinking water storage facility located in the Chatsworth area of the San Fernando Valley. LADWP will be replacing the aging reservoir with two new underground, pre-stressed circular concrete storage tanks and a pump station.

The 102-year old De Soto Trunk Line will be replaced with 48-inch and 54-inch earthquake resistant pipeline along Devonshire Street, Mason Avenue and Roscoe Boulevard.

The City of Los Angeles is committed to a sustainable water future that relies more on local water supplies than costly and unreliable imported water. The plan to increase local water resources includes groundwater replenishment using recycled water.

The Mason Ave and Victory Blvd Mainline Project is a part of LADWP’s plan to replace aging infrastructure in the system and expand LADWP’s seismic resiliency efforts.
