June Monthly Lunch Meeting
You are invited to join us for our monthly lunch meeting, which feature a presentation from Santa Clara Valley Water District's Barton Ching, Christian Ruiz, and Katrina Jessop. Please see below for more information about the presentation topic, speakers, and registration link.
Presentation Topic: Large Diameter Pipeline Inspection, Rehabilitation, and Emergency Repair
The speakers will present the Santa Clara Valley Water District’s (SCVWD) large diameter pipeline management strategy for prestressed concrete cylinder pipe (PCCP) and how it applies to the Almaden Valley Pipeline (AVP), a 72” and 78” diameter PCCP and welded steel raw water transmission pipeline in South San Jose. The AVP is capable of supplying water to the District’s three water treatment plants in Santa Clara County and has numerous turnouts to support groundwater recharge. The District is currently wrapping up an $8.5M project to inspect and rehabilitate the AVP. At the end of November 2017, during the inspection and rehabilitation project, severely distressed prestressed wires in the pipeline were discovered and the pipeline was determined to be near failure. To prevent a catastrophic failure, the District declared an emergency and contracted with Structural Technologies, Pure Technologies, and Simpson Gumpertz and Heger (SGH) to evaluate and repair the pipeline before safely bringing it back to service. The speakers will present on the emergency repair work totaling over $10M, the repair strategy, and forensic investigations.
