Join us for an educational luncheon on a Case Study in Close-Fit Spiral-Wound Lining.
Large-diameter sewer rehabilitation projects often present a combination of structural, hydraulic and constructability challenges that cannot be addressed through technology selection alone. Access limitations, existing pipe geometry, flow management, site constraints and long-term performance requirements can all influence the most appropriate rehabilitation approach.
Using the City of Portland’s Carolina Trunk Sewer rehabilitation as a case study, this presentation will examine the evaluation and application of close-fit PVC spiral-wound lining technology for a challenging large-diameter gravity sewer. The discussion will focus on how project-specific conditions informed rehabilitation selection, the relationship between design requirements and field constructability, and lessons carried through installation and verification.
The presentation will conclude by considering how these decision-making principles may translate to large-diameter sewer rehabilitation in Edmonton and across Alberta, and where spiral-wound lining may fit within the broader trenchless rehabilitation toolbox available to owners, engineers and contractors.

Join us for an educational luncheon on applying ASCE MOP 145 to Gravity CIPP Lining Projects.
Applying ASCE MOP 145 to Gravity CIPP Lining Projects: For decades, the trenchless rehabilitation industry has relied on ASTM F1216 as the primary design and specification reference for Cured-in-Place Pipe (CIPP) rehabilitation of gravity sewers in North America. However, after a newer structural design framework (i.e., ASCE MOP 145) was introduced in 2021, questions are emerging about whether the traditional F1216 approach remains sufficient for modern rehabilitation challenges. While ASTM F1216 provides a straightforward and familiar design method, it was originally developed for relatively ideal conditions and does not fully address challenges such as pipe geometry, large deformations, significant defects, or variability in liner material properties. ASCE MOP 145 introduces a Load and Resistance Factor Design (LRFD) methodology that accounts for uncertainties in loads, material performance, and installation conditions. This approach allows more robust liner designs while improving alignment between engineering expectations and contractor means and methods. This presentation will walk through the procedural steps of both F1216 and MOP 145. Project examples and design comparisons will illustrate how both approaches can be applied to support informed specification and the long-term performance of gravity sewer rehabilitation projects.
