The Front Street Interceptor Project has been named Trenchless Technology Magazine's 2024 Project of the Year in the "Rehabilitation" category.
Insituform Technologies, AECOM, the City of Harrisburg, and Capital Region Water worked together to rehabilitate nearly three miles of the 113-year-old Front Street Interceptor. Situated in the heart of the historic Susquehanna Riverfront Park, the Interceptor is a critical concrete box arch pipe that conveys a significant portion of the region’s combined sewage, handling over 20 million gallons per day during wet weather events. Its condition has long been a concern for Capital Region Water with efforts to address its deterioration reaching a point of urgency.
The project demanded innovative thinking, specialized expertise, and a great deal of patience and precision to rehabilitate this critical infrastructure for long-term durability into the next century. Its distinctive, hard-cornered rectangular shape required use of a recently adopted ASCE standard for non-circular pipe design to ensure both efficiency and success — the first major U.S. project designed using this standard. With the use of CIPP, wetout liner for all 28 installs — some that were more than 1,000 ft in length — were able to be trucked in. This combination of install method, diameter, shape, location, depth and alignment are rare and unique and were the central focus of this $18 million project.
