Ortschlump
The Ortsschlump (also Moorschlump ) was a brook in Hildesheim , which originated at the foot of the Galgenberg . Its water has been used to supply the city with drinking water since the end of the 19th century.
history
The approximately 3 km long local Schlump was one of the source streams of the Treibe , which was the most important stream in Hildesheim's old town in the Middle Ages and early modern times .
From its source at the foot of the Galgenberg in Goslarschen Landstrasse 15, the Ortsschlump initially flowed in an arc to the northwest to the former Sauteiche, which were located on the left and right of Einumer Strasse between Waterloostrasse and the railway line. From there it ran west of the Feldrenne road further north and then turned west in front of the federal road 6 and followed the course of the Fahrenheitstrasse and the Long Garden. To the south of the main station it flowed through the Butterborn, a spring pond ( Born ) in front of the city (from buten: outside), which was located approximately on the northwest corner of the Marienfriedhof. Further to the southwest, he crossed today's Bahnhofsallee and at the level of Angoulêmeplatz, Bernwardsstrasse, and reached Kaiserstrasse at the corner of Speicherstrasse. The Ortsschlump continued along the Kaiserstraße to the Hagentor, which has been widened to the fortified moat since around 1460.
At the Hagentor, the local Schlump left the moat and turned south, but no longer under its previous name, but as Hagenbeke, as Bach ( beke ) , which runs along the northern section of the Lange Hagens , the beginning of today's Cardinal-Bertram- Street to the Hagenbrücke on the corner with Kurzen Hagen. Here he joined with the herkommenden from the Sülte and the stone pit streams to driving and eventually led the Cardinal Bertram Street, the Bohlweg and Hückedahl following in the driving road in Mühlengraben arm of the innermost .
During the Thirty Years' War , the Hildesheimers submerged the area of the former Old Village north of today's main train station for defense by damming the Schlump.
In the first half of the 19th century, the Ortsschlump was relocated in its first section in the course of the preparatory work for the construction of the railway, from the source it now flowed directly north until it reached the field race and so always remained on the eastern side of the Railway line to Goslar . The saute ponds, cut off from the inflow, dried up; they are only reminiscent of the old field name Sauteichsfeld, which gave its name to a street far to the east of the parcel. Around 1880, the Hildesheim main train station was relocated to its current location; The local Schlump, which crossed the new station area, was channeled and laid underground, and the Butterborn fell victim to the redesign of the area.
From 1883 to 2009 the water from the Ortsschlumpquelle was used for drinking water and in 1894 a waterworks was built at the source.
In the 20th century, the Ortsschlump, which had little water left because of the drinking water supply, was channeled further in 1934 when the barracks were built on Senator-Braun-Allee and in 1950 when the Fahrenheitstraße was built, and now flows into Drispenstedter Straße on Kennedydamm Main sewerage.
The road to the Galgenberg restaurant at the local Schlumpquelle was named after the local Schlump in 1965 .
The Ortsschlump waterworks
By 1880 at the latest, the water supply to the growing city of Hildesheim from the Sültequelle turned out to be inadequate and alternatives were sought. In 1883 the city acquired a piece of land near Baddeckestedt for the production of drinking water, but hesitated to build the necessary water pipe due to the high costs. At the same time, the trial development of the local Schlumpquelle began. In 1889, the site in Baddeckestedt turned out to be unsuitable because the extracted water was contaminated by sewage from a plant in Langelsheim that processed the potash salt from the Hercynia potash mine , which went into operation in 1886 .
The experimental well shaft, which was brought into the Ortsschlumpquelle in 1883, supplied satisfactory amounts of water, so that a larger well eight meters in diameter and 11 meters deep was built. By 1887, a storage basin and a temporary pumping station were added, which fed a water pipe into the city with numerous hydrants and public taps ("running posts"). In 1892 the line had reached a length of almost 7 km.
The temporary facility on the site of the Ortsschlumpquelle was replaced by a waterworks in 1894 , which began operations on December 19 at Goslarschen Landstrasse 15. Three steam-driven plunger pumps were installed, which pumped the water into two elevated tanks , each with a capacity of 2000 m³ , which had been erected on the Galgenberg above today's Mozartstrasse. From here a steadily growing network of lines supplied the city, which, in contrast to the previous network, now fed house connections and no public tapping points; these were completely dismantled by the end of 1895.
By 1900 the pipeline network had grown to a length of almost 51 km and supplied more than 3000 house connections with an average of 1200 m³ of water every day. In order to be able to cover the steadily increasing demand, a second, even larger well, ten meters in diameter and 21 m deep, was put into operation this year. Depending on the annual amount of precipitation, the waterworks was now able to provide between 2500 and (at peak times) 6000 m³ of water per day. From 1901 a residential area was built on the slope of the Galgenberg, which was named "Composers' Quarter" after its street name. It was at the level of the elevated tanks, so in 1906 a higher water tower with 90 m³ was built directly behind the Galgenberg restaurant to supply it, which was also filled by the Ortsschlump waterworks; it became superfluous with the construction of further elevated tanks on the Galgenberg in the early 1970s and was demolished again in 1974.
The growing demand for water and the strong dependence of the local Schlumpquelle on precipitation led to increasing bottlenecks and even rationed water supplies. The city therefore began to develop further water resources in 1909 with the construction of the Poppenburg near Elze waterworks a good 15 km away , which began operations on July 31, 1911. In the long term, however, this measure was not sufficient to secure the water supply, so that from November 1934 water was obtained from the Sösetalsperre of the Harz waterworks via a long-distance water pipe . The purchase was expanded in the following years, since 1972 the Granetalsperre , which was completed in 1969, has also been supplying water to Hildesheim, which means that the importance of self-production has continued to decline.
It was not until 1962 that the steam-powered pumps at the Ortsschlump waterworks were replaced by electric ones and the chimney was broken off. In 1985, a water mixing plant was put into operation, which was supplied from the Rottsberg elevated tank with a water mixture of four parts of soft resin water ( hardness 4 ° dH) and one part of very hard water from Poppenburg (25 ° dH). She added the also very hard water of the local Schlumps (25 ° dH) in a ratio of 4 to 1 in order to be able to guarantee a maximum water hardness of 10.6 ° dH in the entire city area. The share of the local Schlump water in the water supply was around 4%. A renovation of fountain 1 was completed in 1989, the now listed elevated tanks on Mozartstrasse were renovated by 2002.
The pumping of drinking water in the local Schlump waterworks was finally stopped in 2009, pumps that were still required were relocated to the elevated tank; however, the well is still available to the fire brigade for emergency supply in the event of a disaster. The work was sold in April 2010 to the local organizer Uwe Brennecke, who wanted to develop a cultural location there, but this failed due to resistance from the residents. The site has been used by a microbrewery since April 2016, but the local Schlump water is not suitable for brewing due to its hardness.
