Join us for an educational luncheon on the project background, design and tendering, and installation of ARROW Utilities’s 1350 mm diameter concrete sewer pipe.
ARROW Utilities (formerly Alberta Capital Region Wastewater Commission) identified 3.2 km of 1350 mm diameter concrete sewer pipe in need of repair or replacement. CIPP lining was selected as the rehabilitation method. The pipe alignment runs through an environmentally sensitive area and is close proximity to residences in other areas. The project was planned to minimize liner installations. A unique process, over the hole wetout (OTHW) was required to accommodate the overweight liners. For this process, the tube is transported to site dry, where a mobile wet out facility is constructed. This is one of few OTH installations in Western Canada.
This presentation describes the project background, design and tendering, and installation with the OTH system.

Join us for an educational luncheon on the Trans Mountain Expansion Project, constructed between 2019 and 2024.
The Trans Mountain Expansion Project, constructed between 2019 and 2024, incorporated over 550 trenchless crossings in varying terrain from central Alberta to British Columbia’s lower mainland. While most of the major crossings were completed using one-pass methodologies such as horizontal directional drills, two-pass microtunneling was used in select locations to tackle some unique challenges on the project. This presentation will cover several completed two-pass tunnels for high pressure pipelines ranging in length from ~120 m to 240 m in a wide range of geological and hydrogeological conditions, while crossing highways, railways, and environmentally sensitive areas.
Presenter: Jake Fei, EIT and Project Coordinator, Stantec
Jake is a Civil EIT and project coordinator with Stantec’s water conveyance group in Edmonton helping clients deliver multi-disciplinary projects. Jake specializes in trenchless design and construction for new installations and rehabilitation projects across Canada and the United States. He dedicated over three years of his career to the Trans Mountain Expansion Project, gaining a wealth of knowledge in trenchless construction where he helped to coordinate and conduct design review of over 50 major and 50 minor trenchless crossings.”
Join the NASTT Northwest Chapter’s Calgary Section for an engaging and informative symposium focused on Trenchless Technology in the local area. This event is designed to provide a platform for education, networking, and showcasing local projects, products, and industry insights. Attendees will gain valuable knowledge and connections through a range of activities highlighting the region’s expertise and resources, including insights from clients, design professionals, contractors, suppliers, and manufacturers.
- Monday, June 2: NASTT’s Trenchless 101 Course covering the basics of installation and rehabilitation, followed by an evening industry mixer to connect with peers and professionals.
- Tuesday, June 3: A full-day symposium featuring exhibitor displays and presentations on the latest innovations and applications in the field.
This event is open to NASTT members, non-members, and students who are eager to explore the advancements and opportunities in trenchless technology. Don’t miss this chance to network, learn, and be inspired by the industry’s best!

Join the NASTT Calgary Chapter for a luncheon on Strategies for Investigating Subsurface Challenges and Evaluating Geotechnical Risk for Complex Crossings.
Through the review of three case studies, this presentation will describe multiple best practices to consider when customizing a geotechnical investigation program, evaluating trenchless methodology feasibility and communicating project risk for complex trenchless crossings. A horizontal directional drill case study examines a crossing with significant elevation difference that crossed protected land parcels a highway and a sensitive river containing thick gravel deposits below the river that extended to the exit at the valley uplands. This urban microtunneling case study handles swelling shales with bentonite and coal seams containing buried glacial valley gravel deposits and a curved microtunnel for a railway crossing evaluates feasibility of several trenchless technologies through a risk assessment of challenging subsurface conditions comprising till with frequent cobbles and boulders having high strength and abrasivity.

Join us for an educational luncheon on the Mill Creek combined sewer trunk, which conveys wastewater and rainwater from south Edmonton to the Gold Bar Wastewater Treatment Plant, built in 1958.
The Mill Creek combined sewer trunk, which conveys wastewater and rainwater from south Edmonton to the Gold Bar Wastewater Treatment Plant, was built in 1958. The service area for this trunk is about 8,200 Ha plus the Nisku & Leduc areas. According to the Multi-Sensor Inspection (MSI) in 2018 and the concept study, the physical condition of the trunk is poor and very poor, especially the section found in Mill Creek Ravine. This trunk was determined to be a high priority rehabilitation project. The main scope includes 890m of 2100mm diameter new tunnel with two shafts, 200m of local sewer reconnection, and abandonment of 860m of existing trunk.
The first phase of the project construction was a micro tunnel which began in March 2023 and was successfully completed in June 2024. This included the construction of a secant pile working shaft next to the Mill Creek School playground, a liner plate retrieval shaft within Tubby Bateman Park, and an HDPE lined 2100mm inside diameter (ID) reinforced concrete jacking pipe installed by micro tunnel boring machine (MTBM).
