The Neusiedl am Steinfeld water reservoir in Lower Austria is the largest water reservoir for Vienna's water supply . At the time of construction, it was also the largest closed drinking water container in the world.

history

The construction of the reservoir in Neusiedl am Steinfeld on the 1st Vienna High Spring Water Pipeline was, in addition to the renovation work on the water pipeline network, after the Second World War the first major investment in expanding the security of the city of Vienna's supply of drinking water.

As Vienna's increasing water demand meant that it was no longer certain that the city's drinking water supply could be maintained for more than four or five days, even with the drinking water reservoirs initially full of around 500,000 cubic meters and the massive use of all municipal groundwater works, another was built Water reservoir decided by the Vienna City Council on November 30, 1951 .

Neusiedl am Steinfeld was chosen as the location for the new container, because the still relatively large gradient of the 1st high spring water pipeline here enabled both the filling of up to ten meters of water and emptying of the container chambers without the use of pumps, thus saving costs during operation.

The idea for such a memory was not new, however. Already around 1930, thought was given to its construction and a large part of the land required for the construction was acquired at that time, additional area could be bought cheaply. The nature of the soil allowed the construction of such a large structure with the use of heavy equipment and the gravel accumulated as excavation material could in part be reused as building material on site after appropriate preparation.

Construction of the Neusiedl reservoir with a capacity of 600,000 cubic meters of high spring water began on August 23, 1953. The official laying of the foundation stone took place on November 21 of the same year. The shell was completed on December 1, 1956; the complete completion took place on July 1, 1958. On April 25, 1959 the container was put into operation.

description

The Neusiedl am Steinfeld water reservoir consists of four reservoir chambers, each 134.4 meters long and 120.4 meters wide, with a filling height of ten meters. Since these chambers are demolished on two sides, the usable content is 150,000 cubic meters each. The ceiling of each container chamber is supported by 288 reinforced concrete columns.

The ceilings of the container chambers were covered with a 45 centimeter thick layer of clay and earth for thermal insulation.

A 306 meter long pipe tunnel was built along the container chambers, in which the supply and discharge lines of the storage chambers, overflow and drainage lines, the necessary fittings as well as high and low current lines for the operation of the gate valves and the control and measuring devices are located.

A control center originally built in a basement room, from which the Neusiedl am Steinfeld water tank was monitored and controlled, was rebuilt in 1994 and now controls not only the tank itself as a sub-center but also the first high spring water pipeline between Ternitz and Vienna.

Since there is no suitable river available as a receiving water that could absorb the water that has to be drained from the container, two soak wells, each 30 meters deep and four meters in diameter, were built. Each of them can absorb around 1000 liters of water per second and feed it into the groundwater.

The construction costs amounted to 103,500,000 schillings (7,500,000 euros), the costs of around 170 schillings (approximately 12 euros) per cubic meter of storage space were classified as very cheap.
