Project Overview
The City of Lubbock initiated the Lift Station 31 Force Main Reroute to modernize a critical wastewater conveyance corridor serving the 34th Street and Quaker Avenue area. As the City’s second-largest lift station, this facility required a reliable long-term solution to accommodate local growth and replace aging infrastructure. MH Civil Constructors was awarded Contract 15659 to execute the reroute, managing a complex scope that integrated the installation of a new 14-inch force main while navigating a high-density urban environment.
The Problem
- Urban Congestion: The project was located in a heavily traveled corridor near a major hospital district, necessitating strict traffic management and minimal public disruption.
- Infrastructure Resilience: The existing force main required a complete reroute and abandonment to ensure system integrity and prevent potential service failures in a high-demand area.
- High-Stakes Operations: Because Lift Station 31 is one of the City’s primary wastewater assets, maintaining continuous service during construction was vital to avoid environmental risks.
- Utility Density: The new alignment crossed a corridor packed with existing utility lines, requiring precise coordination to avoid damaging critical local infrastructure.
Our Solution
MH Civil delivered a comprehensive construction strategy centered on the installation of approximately 4,476 linear feet of 14-inch C900 DR18 force main. The technical scope included the construction of a new 60-inch fiberglass manhole at 34th Street and the systematic abandonment and cleanup of the decommissioned line. To maintain uninterrupted wastewater service throughout the transition, the team implemented strategic bypass pumping and utilized additional flowable fill for structural stability. The project concluded with a full-scale site restoration effort, including the replacement of asphalt, curb and gutter systems, sidewalks, and driveways to return the sensitive hospital district corridor to its original state.
The Results
The Lift Station 31 Force Main Reroute was completed on time and on budget, with the final project value reaching approximately $803,000. The successful installation of nearly 4,500 linear feet of new pipeline has secured the conveyance capacity for one of Lubbock’s most essential wastewater assets. By executing a disciplined reroute approach, MH Civil successfully minimized disruption in a high-traffic area while ensuring the city’s infrastructure is prepared for future expansion. The project’s completion reflects a total commitment to operational continuity and urban safety.
