was found that didn't allow the installation of sheet piles as originally
designed. In order to minimize the project delays, Kingsbury (with its
subcontractors and engineers) quickly redesigned and moved forward
with a new shoring system that required drilling 8 feet deep into the
bedrock to allow for the installation of 20- and 30-ft long casing and
piping to support the sheet piles, along with a new " whale system " to
support the shoring above ground.
The existing raw water intake structure was also repaired. This
required underwater work with divers. Some 1,200-linear feet of 24-in.
pipe was installed to increase the contact time for manganese removal.
The new plant includes a three-bay garage allowing for indoor space
for maintenance, along with a new storage room and a larger room
for staff.
SUPPLY CHAIN
While maintaining operation of the old plant created real coordination
effort, the impact of a slow supply chain, which began during the
pandemic in 2020, was only exacerbated throughout the project
timeline by events like the " Ever Given " Suez canal blockage in 2021
and the escalation of the War in Ukraine in 2022, which created
scheduling and material supply challenges.
This project was also funded by the United States Government with
funds granted through the EPA revolving loan funds, administered
through the Vermont Water Investment Division. This meant that the
project needed to be American Iron and Steel (AIS) compliant, only
adding to the elusiveness of certain materials necessary to construct
the project.
Like many other construction projects throughout the pandemic,
there were longer lead times for electrical components, equipment,
valves, motors, and more that delayed the end date of the project.
Regardless of these many challenges, Kingsbury managed to deliver a
state-of-the-art facility of the highest quality standards that prepares
Brattleboro for the future and recognizes the town's commitment to
sustainability and innovation.
ADDITIONAL CHALLENGES
The sitework of the new facility involved deep excavation for the new
foundations in addition to the new well, which is where the filtered
water is pumped to the storage tank. The existing topography and the
approximately 20-feet deep excavation required the complex design
and installation of a shoring system. As excavation progressed, bedrock

The refurbishment of the two existing filters and installation at the
new facility was also a challenge that required extensive planning and
coordination. The approximately 20,000-lb. filter tanks had to be moved
from the old facility to the new facility with the help of an 80,000-lb.
excavator. Once the filters were brought to the access doors of the
new building, they were put on rollers and slid into their final positions,
making sure they aligned with the newly installed piping and manifolds.
Kingsbury will use lessons learned from these treatment facility
improvements for future projects. Those lessons include the
importance of carefully coordinating with the town and all contractors
to avoid disruption in water treatment service and leveraging modern
technologies that lead to unique and innovative solutions.
