Increased Capacity of the Town of Shelburne’s Water Supply

S. Burnett & Associates Limited (SBA) was retained to determine the best means for the
Town to meet increased water supply demand for the next 20 years. To do so, SBA undertook Schedule ‘B’
Class Environmental Assessment (EA), which is documented in this project file.

The outcome of the EA is the recommendation that Pumping Wells (PW) 7 and 8 be pumped concurrently
at a combined rate of 37.8 L/s to help meet water supply demands. The EA also recommends that the
Town start design and installation of arsenic treatment at PW5/PW6 to allow pumping at a higher rate
while keeping arsenic concentrations below half maximum allowable concentration (MAC) for arsenic.
Additionally, arsenic treatment would allow PW5/PW6 to operate without dependence on blending water
from PW7/PW8, which would increase system resilience if supply from PW7/PW8 was disrupted.

With these improvements, along with ongoing upgrades to PW1 and PW3, the Town is projected to have
enough water supply capacity to meet average and maximum day demand until 2038, at which point a
new well will need to be brought online. Due to the time required to locate, test and permit a new well,
it is recommended that this process start no later than 2033.
