MamaJo Takes a Break

MamaJo took a break last week for the installation of an additional pump that is routinely installed as the tunnel distance extends.  The break was a bit longer than anticipated as a glitch occurred in communication with the Programable Logic Control box.  Crews were successful with troubleshooting efforts and MamaJo was moving again on Tuesday (10/6).  Elsewhere, drop shaft work continued in the photos below that show just how large the tunnel support projects are in neighborhoods along the rivers.

Photos show crews working to ground the Programable Logic Control system. Week of October 5, 2020
