Overview
Advantage Reline successfully executed a complex nighttime rehabilitation project involving a medium-pressure (105 psi) water transmission main. The pipeline, prone to repeated annual failures, ran adjacent to a major freeway interchange, necessitating a minimally invasive, high-efficiency solution to prevent extended service interruptions and significant traffic disruption.

Challenge
The team faced intense logistical constraints: work had to be completed within a single 10-hour night shift under live traffic control conditions. Although the pipeline had no bends, a fire hydrant located mid-span required special accommodation during the lining process. Traditional replacement would have caused major delays and congestion at one of the busiest interchanges in in the city.

Solution
Advantage Reline deployed Primus Line® trenchless technology—a jointless lining system rated for 50 years of service. The project was completed on time and within the traffic control window, featuring three precisely placed access pits and minimal shutdowns, while minimizing water service disruptions and traffic impact.
The fire hydrant was successfully managed in place, and the crew worked in close coordination with traffic control to maintain a clean and secure worksite. Despite the heavy traffic environment, the rehabilitation was completed efficiently with minimal public disruption, no impact on daily commuters, and ensured long-term reliability.
