Project Name: Nancy Creek Tunnel Shafts Odor Control

The Department aims to restore full design capacity of the Nancy Creek Tunnel, providing sustainable relief from sanitary sewer overflows for the Nancy Creek basin community. Three construction shafts were constructed as part of the Nancy Creek Tunnel project. R.M. Clayton and Johnson Ferry Road tunnel shafts anchor the tunnel line, with an intermediate shaft located at Roswell Road. One intake is located at each of the construction shaft sites. The tunnel lift station is located at the end of the tunnel, inside the R.M. Clayton facility.

The scope of the project includes:

• Modifying existing odor equipment located at two, tunnel drop shafts
• Reconditioning odor control equipment (scrubbers) to original factory specifications

Justification:

• Reduces odors in area surrounding drop shafts
• Extends service life of odor control assets
