The Schmalwasser dam near Tambach-Dietharz in the district of Gotha in the Thuringian Forest was used to provide drinking water , which is still used today for flood protection and energy generation. It was put into operation in 1998 after a long trial jam that lasted from 1993 to 1997. The inauguration took place in 1995.
Reservoir
The Schmalwasser dam was built in the narrow water bed and dams the narrow water. 21 million cubic meters of water can be retained. The treatment plant for the raw water obtained in the dam was located below the Tambach-Dietharz dam , to which the raw water was transferred through the mean water tunnel. In 2005, the treatment of raw water into drinking water was stopped in favor of the Ohra dam . Since then, the Schmalwasser dam has been used for flood protection and the generation of regenerative energy . The dam is operated by the Thuringian long-distance water supply .
dam
At 76 m above the valley floor, the dam has the highest dam in Germany. The rock embankment dam has an inner bitumen core seal ( asphalt concrete core seal ). A side overflow on the left slope serves as flood relief . A free-standing drinking water extraction tower can be used for water extraction. The hydropower plant has an output of 420 kW.
The dam is about 3 km from Tambach-Dietharz.
Pumped storage plant
The dam is no longer needed for drinking water supply due to the falling consumption. The location is ideal for the realization of a pumped storage plant , since the lower basin is available. In April 2013, the application documents for the regional planning procedure were submitted because an 80 hectare upper basin has to be rebuilt south or east of the dam. The plans envisaged an installed capacity of 1 GW with construction costs of over 1 billion, Trianel was a potential investor . In July 2018 the project was stopped because of the high costs.
