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. Pont du Gard; Nimes, France Column third story Arch second story first story 4

Arches, especially the arches constructed in the Pont du Gard, were built around wooden frames. The frames were removed upon completion. 5

• 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. keystone 6

• 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. 7

How does an aqueduct work? 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. shaft tunnel 9

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. 12
