Scope/Solutions
The White Rock North Water Transmission Main is a 17 mi, 84 in. dia. prestressed concrete cylinder pipeline, embedded cylinder type, which delivers approximately 200 million gallons per day of treated water. SGH was hired as a subconsultant to Halff Engineers to perform a failure investigation of the transmission main after a pipe segment ruptured.
SGH performed a failure investigation involving the following:
SGH also determined that carbonation of the mortar coating was extensive and variable around the pipe circumference and that the likely primary cause of the rupture of the pipe was carbonation of the mortar coating from acidic groundwater.
