Last of the Pipe Installed at New Irvington Tunnel

The crews have reached a major milestone and installed the last of the pipe for the New Irvington Tunnel.  A 35 ft section of steel pipe was prepped and mortar lined at the surface before being lowered into the Vargas Shaft. This officially completes the entire 3.5 mile water transmission tunnel.  Final steps are being made the next week to disinfect the tunnel and bring it into service to provide a seismically designed connection to provide water to our 2.6 million Bay Area customers.
