This shaft has the largest diameter at 14m so that
the TBM can be turned 90 degrees to head north
after it enters from the east. The turning of the TBM
also occurs in the past. This site is also home to one
of Durham Region’s sewage pumping stations.

This facility pulls air from Shaft 9 – located across
the street – and sends it through a series of
biofilters and bioscrubbers to remove odour through
biological treatment. Next, the air passes through a
carbon filter for polishing before being released to
the atmosphere. The new Odour Control Facility will
be extensively landscaped and will have a green roof
so that it blends in well with the surrounding area.
