Raw Water Intake Tunnel

In 2009, the City of Austin, Texas, authorized construction of a new $508 million water treatment plant located in northwest Austin. Water Treatment Plant No. 4 (WTP4) is scheduled to provide clean drinking water to area residents and businesses by summer 2014. Roughly half of the project consisted of tunneling components where project teams had to closely coordinate with the City and local residents to creatively address a host of environmental and community concerns as well as work through a few construction challenges.
