Project Purpose The West Wilson Utility District in Wilson County, TN, is investing significantly in the community through the future construction of a new water treatment plant, intake structure and associated piping. This water treatment expansion project at Old Hickory Lake is a strategic initiative designed to enhance the district's capacity to meet the increasing drinking water demands that accompany regional growth and development. This paper presents the construction methods, equipment, and technical expertise involved to develop and construct a critical component for this expansion—a new intake and wet well, completed by Garney Construction in 2025. The intake project incorporates a substantial wet well, measuring 35 feet by 60 feet with a depth exceeding 50 feet. This structure offers extensive storage and intake capabilities, which are essential for meeting the water supply requirements of both the district and neighboring areas. The wet well connects directly to Old Hickory Lake via a 60-inch microtunnel casing pipe, ensuring a reliable and efficient conduit for raw water intake. Tunnel & Intake Structure One of the project's most significant high-risk activities involved the retrieval of the tunnel machine. The machine was recovered from a position 25 feet below the lake’s surface and 25 feet above the lake bottom, where it broke through the rock bluff. The tunnel intake system utilizes a 60-inch casing that was bored through solid rock, approximately 60 feet below ground level. This tunnel emerges mid-water, through a rock bluff 25 feet beneath the surface of Old Hickory Lake. Precise engineering, planning, and execution were essential to the successful retrieval operation and the establishment of a secure conduit from the lake to the intake structure. The intake structure itself is designed for optimal performance, featuring three screens installed at multiple elevations. These screens are operated by butterfly valves, allowing selective withdrawal based on current water quality and operational requirements. To enhance durability and protection, four 60-inch submerged bollards have been installed as part of the intake system. These bollards serve as barriers, protecting the intake screens from debris carried by the Cumberland River, thereby minimizing maintenance needs and preventing potential operational disruptions. Collaborative Project Delivery Given the project’s unique scope and complexity, the West Wilson Utility District, in partnership with Owners Representative James C. Hailey, determined that early involvement of the contractor would be beneficial. The project was therefore delivered using a Design-Build approach, with the contractor selected based on a weighted proposal evaluation. This collaborative delivery method enabled West Wilson Utility District, James C. Hailey, and Garney Construction to work closely together from the outset of the project. Such cooperation ensured that the final solution met the owner’s needs and expectations. Additionally, the Design-Build approach provided the contractor with the flexibility to evaluate construction techniques and associated costs prior to finalizing the design, leading to informed decisions and a customized outcome tailored specifically for the project’s requirements.
