WASSERreich - Das Geheimnis des Wassers aus dem Halltal - der Film

Als 1992 ein Murenabgang die Trinkwasserversorgung von Absam und Hall lahm legte, starteten die beiden Gemeinden eines der wohl imposantesten Trinkwasserprojekte in Tirol.
Nach siebenjähriger Bautätigkeit konnte 2001 erstmals qualitativ hochwertiges Trinkwasser direkt aus dem Bergstock des Bettelwurfgebirges genutzt werden.
Der Film zeichnet die rund 10jährige Reise des
Trinkwassers durch das Bettelwurfmassiv nach und veranschaulicht die mühevolle Arbeit der Bauarbeiter und Mineure ebenso wie die geologischen Besonderheiten dieses einzigartigen
Stollens. Abschließend wird der weitere Weg des Wassers aus dem Stollen über die Hochbehälter der beiden Gemeinden bis hin zum Endverbraucher skizziert.

Ein sehr schönes Video. Da bekommt das Wort "Wasser" gleich eine andere bedeutung und man bekommt eine andere Denkweise zum Tema Trinkwassernutzung. Darauf erst einmal ein Glas Wasser

[@thomasmaughan4798]

Incredibly pure water!

[@Radir03]

Warum haben wir so was schönes nicht in Deutschland... Das Trinkwasser sieht sooo lecker aus das ich bei meinem nächsten Trip nach Österreich im Halltal schwimmen, trinken und duschen werde. Freue mich schon

Hello, my name is Donald Richards and I am very interested in Geology. I think the video is about tunneling through bed rock and stabilization of bedrock to prevent cave ins , partial wall and ceiling collapse. I very much liked this video. Thank You for The Great Video.

The Video shows the construction of a water catchment system for the village of Hall and Absam in Tyrol (Tirol) / Austria (Österreich). In the valley of the Inn river east of Innsbruck lies Hall, Absam and Wils. These settlements (Hall 14.000 people) get their drinking water from the north situated Hall-Valley (Halltal) near the Mountain of "Großer Bettelwurf" (kind of: Big rubbish thrower) in the Karwendel Mountain Range. It´s part of the Northern Limestone Alps with Bavaria (Bayern) /Germany (Deutschland) to the North. de.wikipedia.org/wiki/Karwendel de.wikipedia.org/wiki/Gro%C3%9Fer_Bettelwurf @1:30 In the Halltal (Hall Valley) for more than 700 years, salt has been mined (the word "Hall" is often interconnected with salt mining via dissolving it in water, e.g. Bad Reichenhall in Germany) but also the springs in this valley were used for the people in the Inn valley. And nowaday the importance for pure water gets more and more obvious. @2:30 because of it´s location, in average 1800 Litres of water per m² and year fall here. (1800 mm/m²/year). Most of it is retained and seeps away. Because of geology, most of it will return to surface after many years. @3:30 the Karwendel is made of Limestone and Dolomite with plenty of "cracks" / separation planes, therefore ideal for drinking water supply, because water can on most spots get through @4:00 Bettelwurf Mountain Massive has a special watertight geology layer around, which expands up to 3000 m under sea level, daming back the water like a bathtub. Water as snow or rain entering the Massive from above, takes here 10 years until it reemerges as spring water @ 4:30 because of its nature, this region (as the name says: Big rubbish thrower) is prone to rockfall, mudslides and avalanches. In 1992 a big mudslides destroyed a big part of the drinking water springs, and people had to be served for 1 week with tankers, due to impure water and destroyed infrastructure. @5:20 in the same year a big decision was made. The construction of a tunnel to catch the drinking water directly in the mountain. Planning involved engineers, geologists, biologists .... @6:10 Construction began in 1995 with an exploration tunnel. The plan was to break through the Bathtub-layer to get into the aquiferous layer. In 2002 the new water tunnel was finished. @7:00 the tunnel goes up to 1000m into the mountain, after 730m the 40m thick argillaceous schist was reached, which retains the water @7:20 at the "geologist´s window", which was intentionally left open from the sprayed concrete lining, the important geology can be seen at the edge of the bathtub. @7:45 to the left and 30-40 m behind him is the argillaceous schist layer expanding 3000m below, like a dam, to the right the aquiferous dolomite and sandstone layer @8:19 the argillaceous schist layer has no gaps, and @8:24 needles of gypsum/plaster in the schist layer @8:45 this geology was a challenge for the construction, and the water bearing layers could be seen only while advancing @9:20 while advancing in the first 730m in the main dolomite, per day 20 knock offs with about 2m could be reached, when arriving at the geology window, the situation became more difficult, because the mountain was "pushing" and the advance got slower, until they had to dig in 5°C water at 780 m @10:10 more than 200 workers from 18 companies worked for 7 years in 3 shifts continously, with hand work, humidity and low temperatures. 13.000 m³ rock were blasted (1100 truck loads) @11:00 beeing a project for generations, best materials were used, and the site of the entrance building was chosen to be not prone to natural disaster. While construction more mudslides showed the importance of the project @11:25 three main rock layers were mastered, to get from the main dolomite to the aquiferous "Wetterstein limestone" @11:45 the massflow of water gained could only be determined now. A "spring" at 950m with 25 bar and 250 Liter/sec was not enough, therefore 2 side tunnels were constructed. @12:35 for 10 years the water has forced its way through gaps, cracks and splits to reach this point deep inside the mountain. Here it escapes clear and pure. @13:50 after short backdaming the water, it is transported in stainless steel tubes with inside cement and outside plastic lining, reducing check intervals @14:30 maintenance also contains drainig the tunnels and checking for collapses @15:30 the "Wetterstein limestone" can be seen, formed 230 Million years ago in a tropical climate in a lagoon. Then it was lifted up and first Karstification took place (creating hollows) which were filled up later again (colour change) @16:10 when the Alps were formed, it was lifted again, and a second (younger) Karstification took place creating only cracks and no hollow spaces, but enough for water to get through @16:40 to let the water in more easily, borings were made into the rock, because of it´s 10 year journey through the rock, no bacteria or other impurities are found, a unique situation in europe @17:00 an important note is, that the salt layer of Hall is completely separate from this formation. The rock is so stable, that for hundreds of years, no collapses are to be expected, even with earthquakes. 1000m of rock are above the tunnel. @18:05 before the water begins it´s journey to the valley, it has to do some work. A hydroelectric power plant was constructed between the water collecting tunnels and the entrance buliding. 18 Meters of height difference = 85 kW = 500.000 kWh / year with a drinking water suitable Francis Turbine @19:30 finally the water is brought via underground piping to the high-level tanks of Absam and Hall. These serve as buffers and had a general refurbishment in 2010 while operation had to continue @21:55 for removal of old concrete linings, they had to cut open the top floor, then reinstalling stainless steel and new piping @22:40 not only funtional but also a little bit of art, filled with water after a 10 year journey throgh the mountain serving more than 12.000 people ( Anm.: Probably more nowadays) @23:20 How important the decision for this project has been was shown while demolition of the old high-level tank builing in 2010. A mighty thunderstorm once again resulted in a rockfall of 50.000 m³ reaching the entrance portal of the tunnel. But of course the tunnel said: Hold my beer ;) So Hall´s supply with the most important good, clear water, is secured for generations, taking away at least one worry ...
