Since the Rabbit Creek Trunk Sewer Main was constructed in the 1980s, the City of Kilgore has experienced problems with Infiltration/Inflow. Existing 18- and 21-inch Spirolite PVC pipe was improperly installed in poor soils, resulting in severe defects in the pipe and manholes. Freese and Nichols studied the existing condition of the pipeline and determined locations for point repairs and replacement of the pipeline and manholes. The project includes over three miles of 18- and 21-inch PVC pipe with three major road crossings, several creek crossings, and poor soil conditions.
The project received fast-track design in order to take advantage of dry conditions with Freese and Nichols completing design in less than 10 weeks. Landowner issues were resolved concurrently and the project is scheduled to be completed four months ahead of schedule and almost $2 million under the City's original cost estimates. Although the City had secured Texas Water Development Board financing for this project, Freese and Nichols provided cost and schedule estimation resulting in the City forgoing the loans and cash financing the project.
