NOVEMBER 3 & 5, 2020 

Utility Engineering in Transit (Online Workshop)

This workshop will focus on the construction of municipal sewers and watermains using the Microtunnelling trenchless construction method. Over the past several years Ontario has grown from not using Microtunnelling to becoming a leader in North America for complex and challenging projects that include curved installations, and sea and lake outfalls. Microtunnelling construction benefits include: reduced risk during construction, large greenhouse gas emission savings, rapid out-of-sight and out-of-mind construction, and significant reduction in social and environmental costs. Attendees will learn from leading international and national industry experts on state-of-the art construction equipment, processes, design, construction risk mitigation, and quality control and quality assurance. In addition, local case studies will be presented to demonstrate how successful on-time and on-budget projects can be constructed locally. This is a workshop you will not want to miss and is held only once a year.

Lessons Learned from the Industry Experts

A trenchless project has been meticulously planned for months, the crew has been mobilized to site and then something unexpected happens, what do you do? This workshop will be interactive where participants will be presented with actual case studies, given the obstacle presented and then breakout sessions will brainstorm for ideas as to how to resolve this issue at hand. The groups will then deliver their ideas and then compared to actual outcome. This workshop is open to contractors, technical providers and municipalities.

Condition Assessment and Rehabilitation of Culverts

The deterioration and collapse of drainage culverts has become a critical issue for municipalities and transportation agencies. Furthermore, many jurisdictions have experienced severe storms and increased flooding frequencies, an indication of climate change, in recent years. This causes serious damage to existing utilities, roads and public properties in addition to social and financial costs. The municipalities and transportation agencies have to spend millions of dollars on costly repair and reconstruction of damaged infrastructure. Consequently, liabilities and insurance premiums are increased. This workshop will demonstrate how trenchless technologies can provide efficient and economical tools and techniques for pro-active inspection, repair/rehabilitation, or replacement of existing drainage infrastructure.

Styrene CIPP Lessons Learned (Virtual Technology Roadshow Webinar)

Since the early 1970’s, the installation of Cured-in-Place Pipe (CIPP) liners to cost-effectively renovate deteriorate and leaking sanitary sewers and storm drains. Most of CIPP liners use Polyester and Vinyl Ester thermoset resins have a small amount of Styrene. This Styrene is a critical component for the CIPP liner as it acts as a catalyst to transform the resin from a liquid to a hard liner during the liner cure process by the addition of energy in the form of hot water, steam or UV light. During the liner cure, styrene can be released into the air, steam, hot water in concentration that people can smell. 

Recently, concerns have been raised with respect to the health and safety of workers, the public, and homeowners during CIPP lining.  

In 2019 AEGION and the University of Waterloo (UW) completed field study to investigate styrene concentrations and releases resulting from the installation of a CIPP liner in a sanitary main that has lateral connections with water air-filled P-traps. This study used three methods (Photo Ionization Detectors (PID’s), 3M organic Vapor Monitors, and the Waterloo Membrane Samplers) to determine styrene levels within and exiting the laterals before, during and after lining. This Webinar consist of two presentations. The first will be by Dr. Mark Knight who will discuss the AEGION-UW styrene lateral study goals and objectives, key findings, and conclusions. The second presentation by Dennis Pivin AEGION VP Environmental, Health, and Security will discuss AEGION’s proactive approach for workers and the public’s health and safety and newly published NASSCO new guidelines for worker health and safety during CIPP operations.

Rehabilitation of Trunk Sewers, Lessons Learned (Virtual Technology Roadshow Webinar)

Trunk sewers, as with other parts of the water and wastewater infrastructure system, are approaching the end of their designed service life. Many Canadian municipalities have developed asset management plans to renovate these critical infrastructure assets, as they have been experiencing increased storm and flooding events. Trunk sewers are critical parts of the wastewater infrastructure system, as they are typically installed deeper than other utilities. Therefore, their collapse can cause serious damage to other buried utilities, roads, and public properties. Trenchless technologies are proactive solutions that are deployed to renovate and rehabilitate trunk sewers and avoid significant financial, social, and environmental costs. 

This webinar will provide an overview of two challenging renovation projects of large diameter trunk sewers in the City of Toronto. The first presentation will be the “Rehabilitation of Trunk Sewers in Mimico Creek Ravine” by Marya Jetten from Jacobs, and the second presentation will be the “Reflections on the Successful Sliplining of the Humber Sanitary Trunk Sewer” by Mariana Balaban from the City of Toronto. The speakers will discuss the technical and environmental challenges faced during their projects and present strategies and innovative solutions selected to overcome those challenges and successfully deliver the projects.

Tools and Fluids for Underground Success Webinar (Virtual Technology Roadshow Webinar)

Horizontal Directional Drilling (HDD) is one of the trenchless technologies used for the installation of buried infrastructures such as water and sewer lines, gas lines, and telecom and power cable conduits and offers significant environmental and social advantages with minimal surface disturbance. A successful HDD project depends on consideration of important geotechnical factors, accurate bore path design, and selection of proper drilling fluid and equipment such as drilling rigs, rims, and fluid pumps.This webinar will review unique HDD projects where novel add-on technologies and design reconsiderations were applied to address constructability concerns and to solve complex problems.

SEPTEMBER 14 & 17, 2020

Pre-Acceptance Sewers (Online Workshop)

This workshop presents the design, standards and short comings in the pre acceptance of sewers. This is a brand new topic as Municipalities continue to struggle with standards, expectations and acceptance of new construction and rehabilitation projects. The workshop will include case studies that initially rejected acceptance of ownership until a solution was accepted. Case studies will also include the extent of right of refusal. We will hear from three perspectives; Municipal, engineering design and contractor.

SEPTEMBER 15 & 24, 2020

Horizontal Directional Drilling “HDD”  (Online Workshop)

Horizontal directional drilling (HDD) over the past 20 years has become well established an industry accepted method for the installation of new communication cables (telephone, cable, fibre optics) and underground pipelines that transport potable water, sewerage and natural gas. HDD is an environmentally friendly pipeline construction method alternative to traditional open cut. Research has shown that HDD can reduce open cut greenhouse gas emissions by at least 80 percent and results in pipeline construction projects that are completed faster with less disruption to public and environment especially is environmentally sensitive areas such as wetlands and river crossings.

Water Infrastructure Resilience and Climate Adaptation (Online Workshop)

Global climate change impacts, evident from increased frequency and intensity of rain and flooding events, have significant social, environmental and economic implications for Canadian municipalities. In 2013, the Insurance Bureau of Canada estimated insurance losses from natural disasters including Alberta and Toronto flooding to be $3.2 billion. This workshop will discuss useful frameworks and tools to develop water infrastructure resilience and climate change adaptation strategies. The workshop will highlight the impact of climate change on water infrastructure and demonstrate how trenchless technologies can help to renovate and adapt the existing aging infrastructure cost effectively. Case studies will show business case(s) to develop infrastructure renovation programs that can generate large cost savings. Furthermore, decision support tools to help municipalities develop and implement water infrastructure resilience and rehabilitation plans will be demonstrated.
