Body
SUMMARY:
This memorandum provides information regarding the Santa Clara Valley Water District's (District) 10-Year Pipeline Inspection and Rehabilitation Program (Program). The Program implements pipeline inspection and rehabilitation projects for 136 miles of raw (untreated) and treated water pipelines and tunnels, which range in diameter from 20 inches (Campbell Distributary) to 156 inches (Pacheco Tunnel).
The Program budget ranges from $5 to $20M per year to perform pipeline inspection and rehabilitation projects. The budgeted amount covers an average of one to three projects per year, each covering a major segment of pipeline, as well as the development of a dynamic risk model to provide real-time risk of failure information on pipelines. The scope of each project includes an inspection and may include one or more of the following: rehabilitation of pipeline appurtenances such as valves; rehabilitation of distressed pipe segments found during inspection; and installation of an Acoustic Fiber Optic monitoring system to enable continuous monitoring of pipe condition (PCCP only). Additional details regarding the scope of pipeline inspection and rehabilitation work is provided in the following sections.
Pipeline Inspection/Rehabilitation Schedule
A projected schedule of projects/pipelines for the next ten fiscal years is provided below. Note that this schedule may change depending on changing priorities due to pipeline conditions, ability to obtain environmental clearance, and ability to take a pipeline out of service due to other operational constraints. Some short or adjacent pipelines may be grouped together to be accomplished as one project.
