Uplands / North Don Emergency Sewer Repair
This project involved the emergency replacement of an 825mm-diameter trunk sanitary sewer in the Uplands Golf Course for York Region. The situation required immediate site meetings, detailed field investigations, and an accelerated design.
Scope of Services
For York Region, TMIG provided design, contract administration, and inspection services to construct a permanent bypass sewer in a very short time frame and in poor soil conditions. The scope of the project included extensive coordination with York Region, regulatory agencies (MOECC, MNRF, TRCA), and the golf course. All aspects of the sewer replacement were accelerated in order to minimize the risk of an overflow into the adjacent creek. The team was able to stabilize the area and protect the environment from any adverse discharge, provide an emergency replacement of a trunk sanitary sewer while maintaining the operation of the golf course, and restore the creek to prevent sediment migration.
In order to complete the work without impacting the downstream habitat, the creek was dammed with a cofferdam and bypass pumps. During the bypass, the team completed a fish rescue to minimize the impact to the existing aquaculture. To avoid future bank erosion, the banks were also re-graded to a slope of 1.5:1, covered with a coconut fibre erosion control blanket (biodegradable), and sodded with native grasses.
