Purpose and Background
These presentations were recorded at the UESI Pipelines 2025 Conference.
Felix C. Davis WWTP Emergency Rehabilitations (29 minutes)
This presentation detailed an emergency rehabilitation project at the Felix C. Davis Wastewater Treatment Plant in North Charleston, South Carolina, following the collapse of two large drain lines serving the primary clarifiers. The project team faced multiple sinkholes, complex underground conditions, and the challenge of maintaining plant operations during repairs. Emergency declaration allowed expedited procurement and quick engagement of trusted contractors and design consultants. The solution included cured-in-place pipe (CIPP) lining for 700 feet of 48- and 60-inch pipes, along with strategic use of geopolymer lining for additional sections. The project required significant bypass pumping capacity to handle both dry- and wet-weather flows, with innovative approaches to cost reduction and risk management. Despite challenges, including hurricane impacts and tight schedules, the project was completed from design to commissioning in less than a year, restoring full operational capacity and preventing catastrophic system failure.
From Inception to Completion: Rehabilitation of Large Non-Circular Combined Sewers in Winnipeg Manitoba (24 minutes)
This presentation explored a multi-year program to rehabilitate five large, non-circular combined sewer assets in Winnipeg, Manitoba, ranging from 2,000 to 2,950 mm in height. The project addressed aging, partially deteriorated monolithic concrete sewers, some with brick inverts, located in high-risk urban settings with heavy traffic, rail lines, and limited access points. A comprehensive approach was taken from condition assessment through final acceptance, emphasizing system operation, structural design, and risk management. Glass-reinforced plastic (GRP) segmental lining was selected as the preferred technology to minimize flow interruption, accommodate challenging geometries, and provide a 100-year service life extension. Construction was carefully scheduled during winter to reduce wet-weather flow risks, with flexible shaft locations and stakeholder coordination to navigate property and railway constraints. Lessons learned highlighted the importance of early planning, tendering for multiple technologies, and maintaining adaptability when encountering unexpected construction challenges.
Benefits and Learning Outcomes
Upon completion of this course, you will be able to:
- Describe the steps involved in declaring and executing an emergency sewer rehabilitation project under constrained timelines.
- Explain the engineering and construction methods, including CIPP and geopolymer lining, used to restore large-diameter sewer infrastructure.
- Discuss the considerations in selecting rehabilitation technologies for large, non-circular combined sewers, including structural, hydraulic, and operational factors.
- Identify strategies to manage construction risks, stakeholder communication, and flow control in complex urban sewer rehabilitation projects.
Assessment of Learning Outcomes
Students' achievement of the learning outcomes will be assessed via a short post-test assessment (true-false, multiple choice, and/or fill in the blank questions).
