Underground Construction - December 2020 - 27
Delivering Clean Water to Canadian First Nation Communities
reserve side. That contractor used breakers
and vertical drilling to blast the bedrock,
then dug the material out of the way and
trenched the pipe in.
Once the HDD bores to the lake were
completed on the Kenora side, and the
trenching was done on the reserve side,
the project specs called for the two new
pipes to be installed on the lakebed a
little over 9 feet apart.
" The timing worked out really well, "
said Staal. " While we worked on our bores,
the other contractor was finishing the
work on the reserve side. We finished up
on both sides of the lake at about the
same time and were ready to pressure test,
set it up and tie it all in together. "
The pipe was welded together on the
reserve side, and then the pipe - filled
with air so it would float - was pulled into
place with several boats. Divers connected
the pipe to the end of the drill string
above the " daylight hole " (bore exit point
on the lakebed), and Staal's crew and the
Vermeer drill took it from there.
" When we brought the pipe to shore, we
pumped water from our vac truck into the
line to act as a counterweight and get the
line to lay down in the water, so we would
have a better entry angle, " explained Staal.
Once the pipe was pulled into position
and connected on both shorelines, the two
lines were anchored to the bottom of the
lake using concrete weights.
For the Staal team, this Lake of the
Woods water and sewer project was just
another example of how far the company
has come - from only installing sprinkler
systems - in the past decade. Since then,
Staal Irrigation & Contracting has expanded to five HDD crews with five Vermeer
HDDs and several vacuum excavators.
The Lake of the Woods project was one
of the first times the crews have operated a
Mincon air hammer, but Staal said the team
at Vermeer Canada and Mincon supported
them every step of the way.
" We really appreciate all the time those
folks spent with our guys on this job. They
were every bit as invested in seeing us be
successful on this project as we were, and
that means a lot to all of us, " he concluded. *
