The Zweribachwerk is a fully automatic high-pressure hydropower plant in the Middle Black Forest . The machine house is located on the middle course of the Wilder Gutach in the Simonswälder Valley .
history
The pumped storage power plant was one of the first of its kind in Germany to be built in 1923/24 by the Ludin engineering company from Karlsruhe. The long drafted plans for this came from the architect Hermann Alker . The client was the Gütermann company , which had it built for its textile factory.
The upper basin (year-round basin ) is the small reservoir at Lake Balaton at approx. 950 m above sea level. NN at a narrow point (hermitage). Its catchment area comprises about 2.35 sq km on the plateau plate of Kandel Massive at altitudes up to about 1200 m above sea level. NN . Therefore the annual rainfall is considerable here, at least 1800 mm. With the help of the retention volume of the Obersee (10,200 m³) and stream feeders, the power plant has 112 l / s of usable water all year round, with an effective usable gradient (minus pipeline losses) of 462 m. According to measurements, the average total runoff is even 173 l / s, but that much is not diverted with regard to water protection, since the Zweribach should remain below residual water. The length of the pipelines is 2.5 kilometers.
A lower basin there is not, the outlet flows into the Wilde Gutach. The system was also designed for pumped storage operation, but it turned out that the inflow - at that time no precise measurement results were available - had initially been estimated too conservatively and the value achieved during operation was significantly more favorable. The pumping operation at half the power plant output was discontinued after a short time and the associated technology was expanded during an overhaul.
Two turbines from the Voith company from Heidenheim have been in operation since 1925.

Trivia
The approval process at that time used the expression "Sunday water"; the water, which was built up over the weekend according to a precise schedule, should for the most part flow naturally and offer the Sunday excursionists to the Zweribach waterfalls an undiminished experience of nature.
