The Steinfort reservoir pond (also lux . : Stengefort reservoir pond ) was to serve as a cooling water reserve for the steelworks in Steinfort . The building in the form still visible today was started in 1914, but not completed.
The remains of the concrete dam, the locks, a former pumping station, a former turbine house, sewer systems and other things can still be seen today. Some of the decaying buildings and parts of the facility are intended to be retreat areas for bats .
history
The construction of the dam, which is still visible today, began in 1914 when the Steinfort ironworks was owned by Felten & Guilleaume Carlswerk AG . An earth dam had already existed before, but it was not sufficiently tight. The earth dam was built by the owners of the hut from the Collart family at the time. A building permit for the construction of the reservoir was never available.
In 1919 the Steinforter Hütte was handed over to the French company Société des mines de la Loire and the reservoir was not completed because the machines were cooled because of the blast furnaces that were not built, the rolling mill that was dismantled after the war and the non-functioning Thomas steel mill due to the water from the reservoir, it was no longer necessary as originally planned. The blast furnaces in Steinfort were also temporarily shut down due to the global economic crisis .
In 1922 the industrialist Gustave Sinner (March 15, 1881 - April 20, 1953) tried to buy up the forest area around the dams on the Luxembourg and Belgian sides in order to obtain electrical energy from the dam. He managed to acquire around 173 hectares for 800,000 francs. In 1926 he had the dam completed and a turbine house built not far from the dam on Belgian territory . In 1926, however, the turbines were only in operation for a day and a half before the reservoir was emptied. These failures meant that the systems were no longer maintained or operated.
On June 17, 1930, the assistant forester Peter (Pierre) Dostert drowned in the reservoir. The reservoir was drained and the flood gates remained open to this day. In 1932 the Steinforter Hütte also ceased operations.
Position and extent
Coming from Steinfort, the former reservoir is located west to the Clairefontaine district of the municipality of Arlon (Belgium) in the Schwaarzenhaff parcel and had about 10 hectares of water. The Eisch forms the border between Luxembourg and Belgium and the reservoir or the dammed water touched the territory of both countries.
Technical specifications
The dammed water was originally discharged from the reservoir for the ironworks via a 50 cm pressure pipe, through which the water could also be pumped back into the reservoir. The output and yield of the power plant built later was incorrectly calculated. Given the total intake capacity of the turbines of 3500 l / s, the reservoir was empty after around 15 hours.
Reservoir
- Area: approx. 9 to 10 hectares,
- Length expansion: approx. 1500 m
- maximum width: approx. 200 to 270 m
- greatest depth: approx. 7.5 to 8 m
- Storage volume: 180,000 m³ to a maximum of 222,500 m², expansion to 400,000 m³ was planned,
- Locks: 9,
- Lowering target : 291.92 m. ü. M.,
- Storage destination : 298.45 m. ü. M.,
- natural inflow: approx. 153 l / s
- Filling of the storage basin only through natural inflow: at least 17 hours,
The daily inflow of the Eisch is seasonally strongly fluctuating (between about 13,000 and 150,000 m³ / day or at high water up to 450,000 m³ / day) and in this area is on average too low to achieve sufficient water for use by generating electrical energy or to run a profitable business.
power plant
- Turbines: two Francis turbines with a horizontal axis,
- Power: 135 PS (approx. 100.67 kW ),
- Maximum suction capacity per turbine: 1750 l / s,
- Theoretical annual production: 300,000 kWh / year
- Generators:
- Voltage: 5000 volts
- Speed: 1000 / min
- Reserve machine: diesel engine
The turbines are said to have been removed and recycled between 1948 and 1953.
