Southern aqueduct

The southern aqueduct of Selge was equipped with two types of channels: half pipes with an internal
diameter of 0,35m, and blocks with square channels, diameter 0,40m.
Subscriptions on the drawing: Cross-sections of a circular (above) and rectangular (below) pipeline.
The capacity of this southern aqueduct was almost the same as the northern one: 3500 m3,
but its fall was 1/5th: only 0,8%.
