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.
