The Höllentalquellen are several sources on the Rax in Lower Austria , which were taken for the first Viennese high spring water pipeline .

location

The springs, a main spring and three smaller springs, including the Augenbrunnen , are located in the Höllental , the Rax - Schneeberg -Durchbruch der Schwarza , at the entrance of the Großer Höllental , the side valley of the Höllental, which is 8 km above Reichenau an der Rax to the southwest towards the Rax plateau.

history

Site plan of the Viennese high spring pipelines, Höllentalquellen lower center

The Höllentalquelle was planned from the beginning as one of the main sources of the high spring pipeline for Vienna, which was built in the course of the 1860s and opened in 1873. However, through the Reich Water Act of 1869 and the Lower Austrian State Water Act of 1870, the legal position of all those lying below, plant owners and municipalities, was significantly improved. Therefore, the City of Vienna has to fight their respective water law applications through all instances up to the Administrative Court, which took around 20 years. So the spring was not connected to the water supply system until 1893: At that time the first aqueduct had already proven to be inadequate and the second high spring was already being planned.

Since in 1889 the setting of the Höllentalquellen - in contrast to the necessary tunnel connection to Kaiserbrunn - was almost completed, a temporary wooden channel was built in the meantime. In the course of time three other smaller springs were added below. For this purpose, the Schößl (above the mountaineering home) was also removed.

Hydrology and water conservation

The Höllental Quellen belong to a fault zone that can be traced from the Preiner Gscheid to the Klostertaler Gscheid and can be described as the "main drainage" in the area of ​​the Rax.

The springs were made accessible through tunnel tunnels.

The Höllental springs pour around 170–1100 liters per second, that is 15,000–100,000 cubic meters per day, which could make up a maximum of half the total output of the I. High Spring Pipeline, but the water supply fluctuates greatly as with many karst springs. The temperature is usually 6.1–6.4 ° C. The water hardness is 6.8 ° dH, slightly below the average of 7.3 for the entire pipe.

The area close to the springs was fenced in to an extent of 350 hectares, and the path was relocated to the Große Höllental (Schönbrunner staircase) . The large Rax – Schneeberg – Schneealpe water reserve has existed here since 1965 , and there is a strict water protection area within 500 meters . The water protection is entrusted by the Vienna MA 31 (Vienna Water) and MA 49 (Forestry Office) . In addition, there is the European Protected Area Northeastern Randalpen: Hohe Wand – Schneeberg – Rax , a fauna-flora-habitat area with an ecological focus, and the extensive Rax – Schneeberg landscape protection area .

Höllentalquellen memorial

The Höllentalquellen monument

Next to Höllental Straße  (B27) there is an inscription pillar. It bears the Viennese coat of arms and the inscription:

Origin of the sources at the Großer Höllenthale
The inclusion in the Kaiser Franz Josef Hochquellenleitung is under the Mayor Dr. Johann Nep. Prix ​​takes place.
1893

The building is a listed building .
