Body
SUMMARY:
On April 15, 2016, the Board held a special meeting to discuss a major pipeline failure on a section of the Santa Clara Conduit that had occurred in August 2015. The failure of the section of the Santa Clara Conduit highlighted durability issues inherent in the use of the Pre-Stressed Concrete Cylinder Pipe (PCCP). The potential of this type pipe to experience failure has become increasingly acute. Based on analysis of the problem, Staff provided the following recommendations:
* increase frequency of inspections to identify structurally-distressed pipe sections;
* undertake proactive monitoring of PCCP; and
* promptly repair severely distressed pipe sections discovered during previous inspections.
Approximately 77 miles of the 145 miles of pipelines and tunnels managed by the District, are PCCP. The District first began using specialized electromagnetic inspection technology in 2002 and has assessed the baseline structural integrity of approximately 62 miles District-managed PCCP since that time. The assessment efforts from 2002 through 2010 utilized a competitive procurement process between two vendors, Pure Technologies and Pressure Pipe Inspection Company (PPIC). ...
