How is an aqueduct constructed?
The first story is composed of six arches. The second story consists of ten
arches, and the third story carries the water with thirty-five arches.

Arches, especially the arches constructed in the Pont du
Gard, were built around wooden frames. The frames
were removed upon completion.

• An arch was constructed from each end up to the
center piece, known as the keystone.
• The keystone exerts a force on the adjacent stones so
that this one stone at the top held the entire arch
together. Thus, it is the key to the structure.

• The Romans transported water
from far away to cities via
aqueducts.
• Cities had plumbing, providing
private water for the rich and
for public baths. Poor
neighborhoods shared a public
water site.

How does an aqueduct work?
QuickTime™ and a
decompressor
are needed to see this picture.
Water is heavy stuff. It
weighs 8.34 pounds per
gallon.
The Romans needed a
structure strong enough to
hold all that water to
move it from the
mountains into the city.
8
The water was transported in concrete tunnels. The tunnels were
underground if possible. Sometimes the tunnel had to go above ground.
Tunnels could be build with a shaft. This shaft allowed them to take out
dirt and lower supplies to the workers.

water channel
The water flowed in a tube on the top of the aqueduct
called a water channel. The arches supported the water
channel.
10
The channel was lined with concrete. The Romans invented
concrete.
11
How did it work?
• Gravity made the water
flow.
• Roman engineers had
to construct the
aqueduct so the water
would flow.
• The aqueduct was build
to slope down at a .025
meters per kilometer.
