Passage: The aqueduct began at a spring in the area of Nettersheim in the Urft river valley. It then traveled along the valley to Kall, where it had to overcome the divide between the Maas and the Rhine. Wahandisi wa Kirumi walichagua sehemu hii kwa sababu waliweza kushinda mgawanyiko bila kutumia handaki au pampu. The aqueduct then ran parallel to the northern Eifel Mountains, crossing the Erft near Kreuzweingarten (in the Euskirchen district) and the Swistbach with an arched bridge. Intenforst, northwest of Bonn, it passed through the Vorgebirgehlands. Hatimaye, it ran through Brühl and Hürth before arriving in Cologne. Vyanzo vingine katika mkoa huo ambavyo vilikutana na miongozo ya kiwango cha Kirumi na ubora pia vilikuwa na mifereji kuu ya kulisha mto wa juu. Swali: Je, aqueduct huanza kutoka wapi?
Urft
