Title

First Aqueduct Treated Water Tunnels Rehabilitation

Description

The Water Authority has determined that rehabilitation of three existing treated water tunnels is required to prevent additional structure deterioration and ensure system reliability for continued delivery of drinking water to its member agencies. The project entails maintenance, improvement, and replacement of existing First Aqueduct infrastructure, including segments of three treated water tunnels and the bifurcation structures positioned at the upstream and downstream ends of each tunnel. The project would also develop new access manways along the tunnels to improve access into the tunnels for inspection and maintenance. No changes to the existing water supply or capacity would occur.
