GHAFARI ASSOCIATES
jumped to 1,325,000 gallons (5,000,000
liters) per day. Engineers like to have a
high safety margin so as to compensate
for unknowns but the cost implications
of over design can be colossal and at
times not cost effective. A team of
engineers from the Turkish Airlines and
Ghafari visited existing facility as well as
Singapore airlines' state-of-art facility in
Singapore to evaluate their operations.
We agreed that 2.64 gallons (10
liters) per meal water consumption was a
prudent number. In addition we built in
the additional consumption of water for
shower, toilet and other requirements.
Since we had to design multiple
storage tanks for raw water, treated
water and fire protection water for
the initial consumption and back up,
the space requirement for the storage
tanks increased several folds. After
several iterations, we ended up with
total 494,400 ft3 (14,000 m3) water
storage volume. The next challenge was
to accommodate 494,400 ft3 (14,000
m3) of storage tanks and where? The
decision was made to have a remotely
located separate water tank building
due to limited real estate availability
in the proximity of the catering
building. We decided to go as deep
as possible to reduce the water storage
building's footprint. After economic and
hydraulic analysis, we concluded that
the tanks should be 20 feet (6 meters)
deep below the ground and 10 feet (3
meters) above the ground. Total 61,350
sq. feet (5,700 sq. meters) building with
height of 30 feet (9 meters) was the
conclusion. Structural engineers had
to endure another challenge to design
water tanks with strong foundations to
bear water column load of 1,843 lb per
sq. foot (9,000 kg per sq. meters) plus
structural and miscellaneous weight.
We accommodated 38 water pumps
including fire pumps in addition to
spaces required for softener plant,
electrical room and telecom room in
basement.
