SSAT Hot Water Tank Replacement Scope
Replace two hot water tanks with new hot water tanks including all
associated infrastructure
Estimated total cost $1.1 million

Energy Efficiency & Asset Life
The new tanks are semi-instantaneous heat, which should reduce the
energy demand as they will not be constantly heating water (even if no
demand exists as the previous tanks did).
The previous tanks had an asset life of 40 years, however, the tank failed
at 15 years. Other areas of the airport had tanks fail around the 15-year
time frame. Maintenance, along with Facilities and Infrastructure are
moving forward with new tanks having an asset life of 15-20 years in the
future.

Complexity of the Work
The mechanical room where these tanks are located has been modified
multiple times since installation. Currently, there is not enough space to
remove the old tanks in one piece and will require the tanks be cut up
for removal.
New equipment was designed to be small enough to fit in the room and
still meet the operational needs. However, the new tanks will have to be
lowered around 20 feet from an access hatch on the ramp level.
Other modification are needed to the plumbing components to properly
operate the newer type of hot water tank.
