Roman Aqueduct Excavation (Römerkanal)

An old Roman aqueduct runs here in the valley. The old lines were exposed in various places.

The four branches of the Eifet Water Pipeline to Cologne were all fed from spring catchments, with the water collection methods adapted to the respective water resources. At the Grüner Pütz, an 80-meter-long drainage pipe was used, the upstream side of which was constructed without mortar, thus allowing water seeping from the slope to penetrate. The downstream side was constructed differently, as mortar and an artificially inserted clay seal ensured that, on the one hand, no drinking water was lost and, on the other hand, the stream water from the Urft Valley was kept out of the canal.A cover made of massive sandstone slabs and a gravel bed on the bed, which was otherwise unimproved, also served to keep the spring water clean.Source: Display board
