This project is to preserve 3,500 feet of the existing 72-inch Chambers Creek sewer main, called an interceptor tunnel. The concrete tunnel has eroded over time due to hydrogen sulfide gas which is produced by naturally-occurring bacteria.
To rehabilitate and protect the tunnel, it has been relined with fiberglass reinforced pipe.

Current Status
The tunnel rehabilitation is now complete and the project is in its final stage which includes removing the bypass pipe and equipment. The project is on schedule to be completed in June.

Bypass Pipe
A 2,700-foot long wastewater bypass pipe installed along the north side of Chambers Creek Road and across parts of Chambers Creek Properties rerouted wastewater during the day so work could be performed in the tunnel. The bypass pipe was removed in early May except for driveway crossings. More about the bypass

Recreational Impacts
The bypass extended south in the general direction of the Chambers Creek Regional Wastewater Treatment Plant, crossing the Chambers Creek Properties recreational play fields and perimeter trail. The pipe is in the process of being removed from the Chambers Creek Properties recreational areas, however, until the work is complete pedestrians, cyclists and others using the trail and play fields are encouraged to be aware of obstacles and use caution.
Removal of the bypass pipe and temporary construction shafts on Chambers Creek Road are currently being removed and and the road will shortly be restored to its original condition. Final project completion is expected by June 2012.
