First time… tanks on the move
In 2003, New Brunswick Power, located in Coleson
Cove south west of Saint John, worked with Greatario
Engineered Storage Systems, from Innerkip, Ontario, to
come up with an environmentally friendly solution to
holding their wastewater.
The tanks that were built are an integral part of a treatment
system which was designed to process wastewater
from both the power house and the flue gas desulphurization
plant of an Orimulsion-fired generating station. Each tank
was required to possess a corrosion resistant layer on the
interior surface. Also, the agitated tanks were fitted with
internal baffles and top mounted mixers. The tanks were
then interconnected with platform walkways, pipe support
and steel agitator platforms. With the new process, they are
now able to stabilize the water to allow for a safe release into
the environment. Greatario designed and installed the complete
tank and walkway package.
The amount of storage needed was 1800 m3, as
well as treatment of wastewater and processed water,
so four tanks at 28’ dia. x 28’ high were designed and
erected at a nearby warehouse, and then transported
by tractor and float to the site. This is the first time
Greatario has ever built off site, and then transported
the bolted tank to its location. This decision was made
so that they could avoid weather issues while building
in March, and so that crews could work around the
clock to complete the job faster.
