The San Diego County Water Authority’s Pipeline Relining program takes a proactive approach to pipeline maintenance. This 30-year program focuses on pipelines showing signs of deterioration and joint damage during internal pipeline inspections.
The projects listed below consisted of the manufacture of 57,000 ft of 67 inch & 69 inch diameter welded steel liner inside pre-stressed concrete cylinder pipe.
- Pipeline 3 Sweetwater To Lower Otay Relining-32,000 Ft
- Pipeline 3 San Marcos To Twin Oak Relining-28,000 Ft
ON-SITE provided fabrication inspection, Welding Engineering support during installation and Phased Array Program Oversight support during the installation of the steel liners. ON-SITE also assisted in the development of Phased Array Advanced Ultrasonic testing program, forensic analysis and root cause determination of material failure of steel during manufacturing processes.
