Rampart Pipeline

BT completed the first two of three phases of a critical infrastructure project for the City of Aurora between November 2021 and March 2024, with the final phase scheduled for winter 2025. This project involved slip-lining a 48” steel liner pipe into an existing 54” PCCP waterline that runs through the densely developed Denver Tech Center. This line is a vital component of Aurora’s water system, connecting the Aurora Rampart Reservoir to the city. Due to the high importance of this line, all work must occur during low-demand winter months when outages are permissible.

Challenges

Limited seasonal shutdown windows and tight completion deadlines
Confined space entry was required throughout, which heightened safety risks and necessitated continuous airflow management
Narrow tolerance between the liner and host pipe

Solutions & Approach

Created innovative solutions and detailed planning
Utilized custom-engineered carts explicitly designed for this slip-lining project, allowing for precise and efficient installation of the steel liner inside the existing pipe
Careful execution and a commitment to safety and quality

Results

Despite the complexity and schedule pressures, we delivered both completed phases on time, with the line successfully restored to service by the deadline. The City of Aurora was highly satisfied with the results and has since relied on BT for multiple emergency projects. This ongoing relationship reflects the trust and confidence BT has built as a reliable contractor for critical infrastructure work. The team now looks ahead to completing the third and final phase this coming winter.
