Document Description
Metropolitan has performed electromagnetic inspections of the Box Springs Feeder, a 96-inch diameter prestressed concrete cylinder pipe (PCCP), originally installed in 1975. The electromagnetic inspections have revealed anomalous readings at 14 locations. The extent of damage, if any, at these locations could not be interpreted by the electromagnetic inspections due to the presence of internal steel bands within the pipeline. Metropolitan has authorized a study to determine the condition of the anomalous sections. Metropolitan will excavate pipe sections at three locations to determine if radial cracks are present in the exterior of the pipe, and remove the steel bands for inspection.
