Lainz water tank
The Lainz water tank is a drinking water tank in the Vienna water supply network . The water tank was built as the 21st water tank in the city of Vienna between 1935 and 1938. At the time of its construction, it was possibly the largest closed drinking water tank in the world.
location
The Lainz water reservoir is located in the 13th district of Hietzing, on the edge of the Lainzer Tiergarten , around 190 meters from the Mauer transition chamber. It is fed by the Second Vienna High Spring Water Pipeline . The tank's operating water level is around 327 meters above sea level.
history
The investigation of the planned building site in the area of the then market town of Mauer began before 1935 when 23 trial excavations were carried out only a few meters deep in order to get a first impression of the soil condition. At the beginning of 1935 three of the originally planned 14 test drillings were carried out by the Latzel und Kutscha company up to 46 meters below the planned building base. In addition, the Swedish company AB Elektrisk Malmletning was commissioned with a geophysical soil survey. Later another 12 shafts up to 5 meters deep were sunk.
Around 5 hectares of beech and oak forest fell victim to the construction of the Lainz water reservoir on the area of the Lainzer Tiergarten immediately on its border as the owner of the Tiergarten was killed by the War Damaged Fund. The clearing the site and the removal of humus was made in accordance with the start of the actual excavation work by the General Construction Company A. Porr and J. Takacs & Co .
The actual construction work was carried out by the companies
- General construction company A. Porr ,
- Universale Redlich and Berger Bau-AG,
- H. Rella and Co ,
- FS Swittalek's widow and
- G. and W. Gröger .
In order to be able to employ the largest possible number of unemployed, the approximately 200,000 cubic meters of excavation was carried out almost exclusively by hand. A backhoe was only used temporarily. A field railway with four gasoline locomotives was used to transport the excavated material.
In the years 1992 to 1994, the drainage system of the container was rebuilt, so that the storage volume could be increased.
description
Due to the adaptation to the terrain, the reservoir was given an irregular floor plan and two container chambers of different sizes. The southwest chamber covers 14,604 square meters and the northeast container chamber 9,834 square meters. The 24,438 square meter and around 25 centimeter thick container ceiling including the covering of earth is supported by a total of 648 meters long outer wall and a 146 meter long central wall - both with a wall thickness of at least 35 centimeters - between the container chambers and 790 columns in the container chambers. The ceiling and the outer walls were protected against the ingress of seepage water with bitumen coatings , rubbed plaster and a Torkreth skin . The inside of the container chambers was provided with friction plaster, which is intended to prevent high spring water from escaping from the container.
In the middle of the front facing Wittgensteinstrasse is the valve chamber with the inlet and outlet pipes and the associated valves . This single-storey building was designed with smooth stone blocks, with recessed wall panels and corner pilasters in the New Objectivity style . The forecourt is flanked by walls with embossed artificial stone blocks.
dimension
The capacity of the new tank, now 143,620 cubic meters, corresponded to around 43 percent of the total storage volume of around 336,000 cubic meters available to the Vienna waterworks. At the same time, the Lainz water reservoir was 21 percent larger than the previously largest reservoir, the Rosenhügel water reservoir .
