The first section of the aqueduct contains 36 semi-circular arches, rebuilt in the 15th century to restore a portion destroyed by the Moors in 1072.
The line of arches is organized in two levels, decorated simply, in which simple moulds hold the frame and provide support to the structure.
On the upper level, the arches are 5.1 meters (16.1 ft) wide.
Built in two levels, the top pillars are both shorter and narrower than those on the lower level.
The top of the structure contains the channel through which water travels, through a U-shaped hollow measuring 0.55 tall by 0.46 meter diameter.
The top of each pillar has a cross-section measuring 1.8 by 2.5 meters (5.9 by 8.2 feet), while the base cross-section measures 2.4 by 3 meters (7.9 by 9.8 feet).

The aqueduct is built of unmortared, brick-like granite blocks.
During the Roman era, each of the three tallest arches displayed a sign in bronze letters, indicating the name of its builder along with the date of construction.
Today, two niches are still visible, one on each side of the aqueduct.
One of them is known to have held the image of Hercules, who, according to legend, was founder of the city.
The niche now contains an image of the Virgin, and the other one, used to hold another one of Saint Stephen, now lost.
