course

The Solgraben begins at a height of about 147  m above sea level. NN in the spa area of Bad Nauheim at the intersection of Lindenstrasse and Zanderstrasse on an elevated terrace on the edge of a park around Gradierbau I (with inhalatorium). Its warm brine comes from Sprudel VII (also Great Sprudel , from 160 m depth with 30 ° C) and Sprudel XII (also Friedrich-Wilhelm-Sprudel , from 180 m depth with 33 ° C). It initially flows in an easterly direction along Lindenstrasse and after 75 m turns south-southeast on Goethestrasse , flows past Gradierbau I, crosses under Eleonorenring at the Solgraben bus stop and then runs past school facilities such as the Ernst Ludwig School and the Vocational School Schools at the graduation tower. It finally flows out at an altitude of about 146  m above sea level. NN from the northeast into the brine basin created around 1850 near Gradierbau III at Ludwigsbrunnen , where the brine can be further clarified and stored before it is spread.

character

alabaster

The Bad Nauheimer Solgraben is an artificially created open canal to fill the brine basin with brine and to operate the graduation houses fed from it, which are called graduation buildings in Bad Nauheim . The brine comes from boreholes that were sunk in today's Sprudelhof in the 1840s after a light earthquake. Part of this brine was used for spa and bathing operations. Today it is led from the Sprudelhof in underground pipes to the "source" of the Solgraben. Its initially warm, rust-colored water is rich in salt and iron. Despite the physical and chemical conditions, plant and bacterial life exist in it, which rather forms colorless biofilms. Due to the continuous change in the physical and chemical conditions in the brine, dissolved minerals fall out over time in the form of white flake-like flakes and collect in places on the ground. Because of this and because the Solgraben absorbs fallen leaves, it has to be cleaned (desludged) again and again.

The brine ditch and the brine basin are technical facilities of the former Nauheim salt works. They have no connection to the USA , except that the brine basin can be drained via an underground channel to the USA opposite the Ludwigsbrunnen in the event of an impending overflow in order to prevent the uncontrolled drainage of brine from the ditch before it enters the basin. The brine basin cannot overflow because its edge is higher than the height of the mouth of the brine trench.
