The Mauer aqueduct is a listed building of the Vienna water supply in the course of the 1st Viennese spring water pipeline in the 23rd Viennese district of Liesing .

The curvilinear and 23 meter high aqueduct crosses Endresstrasse in the Mauer district . Its total length, of which only around 200 meters are freely visible, is 533 meters. The building is protected by the Hague Convention for the Protection of Cultural Property in the Event of Armed Conflict .

60 arches, each with a span of around 1.3 to 1.9 meters, are covered over and therefore not visible. There are 12 free-standing arches with a span of around 12 meters each and one with a span of around 16 meters.

Between 1870 and 1873 this valley crossing between Sauberg (259 m) and Steinberg (256 m) was built from non-frost-resistant bricks as well as cuboids and rubble stones. Moisture and the change in temperature affected the bricks in such a way that the structure had to be renovated using a method developed by the Vienna Waterworks and used in the renovation of the Mödling aqueduct, which was also part of the 1st Vienna High Spring Pipeline, between 1999 and 2004. The outer wall layer was removed with the help of a rope cutting process and then a new wall was built. A gap was left between the new wall and the old building, so that the ventilated façade both secures the building and protects it from the weather. Parts of the supporting arch construction were also renewed. The aqueduct continued to be used for water supply during the renovation work, which began in 2007 and was completed in June 2011. The costs were estimated at around 8 million euros.

The vault of the duct was built from conical shaped bricks. The top of the duct was covered with quarry stone paving, which was bordered on the sides of the aqueduct by cornice blocks. Later, an asphalt coating to which “Boschin” - a paint made of asphalt and rubber - was added was applied as additional weather protection. Boschin's job was to keep the asphalt elastic and prevent cracks from forming.
