This contract consisted of modifying and replacing
existing equipment for the MWRA at the Deer Island Treatment
Plant. The facility operates 24 hours a day, seven days a week
while maintaining full operation during the demolition and
installation stage making the work schedule a challenge that
J.F. White was able to meet.
At the Winthrop Terminal Facility 8 MCC buckets were
modified to power 3 new conveyor and screen systems. A
new programmable logic controller was installed to
synchronize the operation of the air driven system and the
conveyor screens.
The four existing Drum Screens, conduits and wiring
in the Primary Scum Room were demolished and replaced
with new equipment. J.F. White installed PVC coated rigid
conduit, wire, field instruments, devices, disconnects and
control stations. GAI-Tronics Communication System, fire
alarm upgrade and gas detection system was also installed .
Most work was performed in hazardous areas where TYVEK
suits and respirators were required.
