Brewing water art in front of the castle gate

from Wikipedia, the free encyclopedia

The water art in front of the castle gate was a Lübeck water supply system .

background

Since the brewing water art, which was commissioned in 1294, could only supply the south-eastern part of the city, the brewers based in the north-western part had another system built at their own expense in 1302 so that the water required for brewing beer in large quantities can also be obtained via a pipe network at any time.

The attachment

In contrast to the existing brewing water art on the Hüxterdamm , which was operated from the beginning by means of a water-driven bucket wheel and later by a pumping station , the new system managed without any conveying mechanism. It was a pure gradient system in which the difference in height between the inflow in the dammed Wakenitz and the tapping points was sufficient to generate the necessary water pressure. A wooden pipe on the bottom of the Wakenitz, the inlet opening of which was north of the Schafferturm , took the water and first carried it to a sewage water tank . From there, the underground lines led it along the city wall to the castle gate and from there into the city center.

The pipeline network

The Burgtor-Wasserkunst supplied the northwest of the city island to the Beckergrube through branch lines . The network extended to the Engelswisch , Kleine and Große Altefähre as well as the Kupferschmiedestraße .

The wooden pipes initially consisted of grooved beams with nailed-on covers; later, as in brewery water art and civil water art, pierced tree trunks were used.

Tapping points placed in the houses were not common with this water art. Instead, there was mostly well sod on the border between two houses; they were covered and fitted with handle pumps , the handles of which were always removed by the brewers after use. In this way, the withdrawal of water by unauthorized persons was prevented, as was unnecessary consumption.

The pipeline network had a total length of 1,840 meters and remained in use until 1867, when the new water art began operating.
