Helping Municipalities to Identify Appropriate Rehab Technologies for Sewers

Many municipalities have collected a large amount of CCTV data on sewers and manholes. However, they often struggle to use the inspection data to answer three fundamental questions: What assets should be fixed? When they should be fixed? and How they should be fixed?

Join us for this band new workshop to help municipalities identify appropriate renewal techniques based on the condition assessment data. Attendees will learn about the tools to aid data management and decision making. Furthermore, benefits and limitations of various sewer pipe rehabilitation techniques will be discussed.

Municipal Construction of Sewers and Watermains Using Microtunneling

This one-day 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.

Manhole Assessment and Rehabilitation

This workshop presents the inspection and trenchless rehabilitation methods for maintenance of holes. It addresses the growing problem of manhole deterioration. Inflow and infiltration solutions have been discussed extensively for sanitary and storm sewers. However, these measures may be limited if manhole chambers are neglected. Consequently, an increasing amount of attention has been paid to the rehabilitation challenges facing sewer maintenance holes. As in other aspects of the sewer systems where trenchless technologies are replacing excavation, this seminar will highlight the inspection and trenchless rehabilitation methods for maintenance holes. More details coming soon. Location: Mississauga Grand, 35  Brunel Road, Mississauga.
