Colliery Dams Update

Summary

Preparations are currently being made for drilling that is set to begin next week in the Colliery Dam Park work zone.

Copcan's subcontractor, Henry Drilling, will commence work on a secant pile cut-off wall on Monday, October 19th. This work entails drilling a hole while advancing a steel casing. When the proper depth is reached, the casing is removed as concrete is poured. A series of overlapping concrete columns will form the cut off wall. The cut off wall supports the labyrinth weir excavation and prevents seepage from the reservoir. It is anticipated the cut off wall construction will take three weeks to complete.

Review of the site resulted in an assessment that between two and six more trees will require removal along the access road to allow room for the drilling equipment and low bed trucks to enter the area. An empty truck will be brought in to ensure only trees necessary to allow access are removed. The removed trees will be kept for park use.
