The sections of the built underground pipeline and the cistern’s remains near the Giannoula stream, to the northeast of the Kyrillos hill, belonged to the extended aqueduct sponsored by the emperor Hadrian. The pipeline was connected to the exposed Eleusinian pipe. Furthermore, a small section of an underground pipeline run along a stream to the south of the old Saint George bridge, in Aspropyrgos. This was most probably a branch supplying water to the coastal area of the eastern Thriasian Plain. More exposed pipes have been excavated in Eleusis, along Dimitra Street, near the Pompeion and the end of the Sacred Way.
