Greenway Waste Water Treatment Plant

Scope: Caisson Wall, Tiebacks

The Project

Removal of existing UV equipment, construction of new concrete channels in the adjacent location and installation of new UV equipment and associated appurtenances.

The Challenge

The requirement was to construct this project beside an active road to be maintained for access to a busy pedestrian path and dog park. In addition to the access constraints, a high water table was present that fed into the Thames River.

The Solution

In order to construct the new tank, Maple Site Solutions Inc. implemented a temporary secant wall to support the existing access road and to cut off ingress of any water into the proposed excavation.
