Plan of the area behind the castellum. In the north (top of drawing) the supply channel / aqueduct
(Zuleitungskanal). Letzter Revisionsschacht = Last manhole. Eingang = Entry. At the bottom of the
drawing the three outlets: west, middle and east. Note that only 112 m of the aqueduct channel is
passable – the only known part of Pompeii’s aqueduct. Drawing from Ohlig 2016.
