Provenance Engineering was selected by the city to provide the design, bid, and construction phase services of a 4,475-linear-foot project, installing a new 14-inch fusible PVC pipe for force main for Lift Station No. 31 (Lubbock’s second largest lift station). This project included a route study to determine optimal alignment and an assessment of rehabilitating the existing 12-inch cast iron force main.
Project Components:
- Trenchless Construction
- 4,475 LF of 14-inch Fusible PVC Force Main
- Route Study
Challenges
The project required rerouting the force main under Quaker Avenue, a heavily trafficked area serving a key hospital district, without disrupting operations. Additionally, increasing the force main diameter for future growth needed to avoid impacting the lift station’s existing hydraulic system curve, thereby preventing pump replacements and additional costs.
Solutions
Provenance Engineering proposed a trenchless construction method to minimize disruption and maintain the lift station’s operations during the project. The rerouted pipeline allowed continuous functionality, eliminating the need for costly bypass pumping and reducing downtime, ensuring the project met the City’s needs efficiently and cost-effectively. This project was completed on time and on budget.
