Duderstadt Gallery: Section 9 - Aqueduct

CONSTRUCTION OF THE AQUEDUCT: PART 2
Only when it neared the city was the water channel raised on the still-visible series of arches set on pylons with rusticated blocks. Rustication was a purely decorative practice: the aqueduct was meant to be an impressive sight as it approached the urban area. The arcaded segment of the aqueduct terminated in a receiving tank, which pressurized the approximately 800-meter length of inverted siphon that crossed the final valley to the Nymphaeum beside the northern city wall. The siphon was raised on a series of low arches to reduce the pressure. From the Nymphaeum, the water was distributed to other parts of the city.
