InfraTerra Inc. has been awarded a contract to provide seismic vulnerability assessments and repair time estimates for San Diego County Water Authority pipelines.

A unanimous SDCWA board vote, Jan. 23, authorized the award of a $724,939 contract for InfraTerra to perform the work. The study is expected to be complete during summer 2021.

The CWA has five large-diameter pipelines with prestressed concrete cylinder, reinforced concrete and welded steel pipe. The most recent major seismic vulnerability study on the CWA pipelines was performed in 1993 and provided an estimate of the number of pipe breaks and repair time needed to restore water service in the event of a significant earthquake.
