Provenance Engineering was selected to design, bid and construction phase services of 4,475 linear feet of 14-inch new fusible PVC force main for Lift Station No. 31 for roughly $800,000. The project included a route study to determine the optimal alignment and assessment of rehabilitation of the existing 12-inch cast iron force main. This project has given our founder, Kent Riker, PE, an opportunity to finish working on the second-largest lift station in Lubbock, eighteen years after working on the replacement of the lift station, while working for the City of Lubbock. The force main was not replaced during the lift station rehabilitation due to its challenging location under Quaker Avenue.
Challenges
Evaluate a force main reroute – with minimal disruption – for the City of Lubbock’s second-largest lift station, which serves a hospital and runs along a major City Street that is often congested with heavy traffic. Address any hydraulic changes caused by increasing the diameter for future growth and increased length of force main while not affecting the existing Lift Station No. 31 pump’s system curve, therefore requiring pumps to be replaced increasing adding capital costs to the project.
Solutions
Provenance Engineering presented the City of Lubbock with a trenchless solution, which allows a non-invasive construction method. Rerouting the pipeline also enabled the continuous operation of lift station No. 31 during construction, eliminating costly bypass costs and minimizing shutdown time.
