Atlanta takes delivery of TBM

4 July 2016 , 0

The City of Atlanta has welcomed the arrival of the largest section of a new tunnel boring machine (TBM).

The TBM will be used to excavate a tunnel to connect the Chattahoochee River and the Hemphill Water Treatment Plant to the former Bellwood Quarry.

The machine is part of the city’s USD$300 million investment to address aging infrastructure and will excavate the five mile tunnel that will fill the quarry and increase the water reserve from three to 30 days.

The almost 30 foot, 57,000 pound front main beam is one of the first and largest sections of the USD$11.6 million TBM to be delivered from Ohio on more than 70 trucks, before it is assembled on the quarry floor.

Watershed Management Commissioner Kishia Powell said “Now, more than 130 years after Atlanta acquired its first dependable water system in the late 1800s, we are working to ensure a sustainable and modern water infrastructure for the city.

“This machine represents the next century of clean water for our community, and that’s why we’re so excited to have the public help name it.”

The project is scheduled to be completed by December 2018.
