Schematic drawing Aspendos aqueduct

Schematic drawing of the remains of the Aspendos inverted siphon as seen from the west, and a schematic map showing the same (in brown). North is on the lefthand side. HT – header tank. NT – north tower. ST – south tower; RT – receiving tank. The final section from the south tower to the receiving tank is shown in frontal view, normal to the aqueduct. The red horzontal line indicates the level of the header tank, the blue line the hydraulic gradient. The green line is a reconstruction of the original top of the inverted siphon.
