The Village of Pemberton is
a spectacular 20-
minute drive north of the Resort Municipality
of Whistler in British Columbia. The Village,
located at the foot of the majestic Mount
Currie and adjacent to Lillooet River, is in the
heart for the Pemberton Valley.
The area was developed at
the turn of the
century as a result of forestry and agriculture.
Community appreciation of their environment
is evident in the Village’s mission statement:
Committed
to building and maintaining a
Village, which preserves and enhances the
natural environment, heritage and uniqueness
of our community.
Since 1996, the Village has experienced
an amazing 250% population growth and
currently has a population over 2000. The
growth of the community is a result of the
economic growth in the region. However,
growth had placed a heavy burden on the old
wastewater treatment system. The Village
Wastewater Treatment Plant reached its
capacity in 2003 and was not considered a
viable candidate for upgrading.
Recognizing the urgent need
to address
problems with the wastewater treatment
system, and to build more capacity to
facilitate continued growth, the Village
retained Associated Engineering as the
Program Manager to oversee the design,
construction, and commissioning of a new
wastewater treatment plant for the Village of
Pemberton.
Associated Engineering prepared a Request
for Expression of Interests and Request
for Proposals for this project, which was
delivered under a Design/Build contract. The
terms of reference embraced Village’s
mission statement.
Treatment Plant Administration and
Process Building

The design/build contract was awarded to
contractor, Maple Reinders. During the
process, Associated Engineering maintained
close and continuous
communication with
Maple Reinders and
the Village, and
managed the related
environmental and
regulatory provisions.
The project was
delivered on schedule.
Construction was
completed in less
than one year and
the new treatment
plant was commissioned
in February 2005. The new treatment plant will service
5000
people with ability to upgrade the capacity to 7500 people.
The plant
process includes influent fine screening, aerobic biological
secondary
treatment process, final equalization and clarification,
effluent
disinfection, river outfall, sludge stabilization, and
sludge dewatering.
This treatment plant project, along with
the sewerage system
upgrades, ensure that the Village maintains its sustainability
during
the coming years.
Associated Engineering’s staff involved
in the project were Paul
Dufault, Arash Masbough, Rick Corbett, Ed Bird, Dave Forgie,
and
Les Pickard. Brian Kirk, Hedley Crowther, and Shantelle
Clarke from
the Village of Pemberton oversaw the project. |
