Ashby Jett Sewer System Improvement

Atlanta, Georgia

The project involved 1,275 feet of Gravity Flow and Sewer Outfall to be completed parallel to a Proctor Creek Tributary Stream running adjacent to and south of the Bellwood Quarry. The new pipe was 30" Hobas and installed by open-cut method.

The conditions of the right-of-way were considered outfall and low-lying areas with clearing required for the entire length. Access is limited, and road building had to be completed to allow the work to move forward. Major by-pass pumping was required.
