The pipe trench, which provided water to stamp mills, washing works and tin smelteries in Ehrenfriedersdorf, was constructed in the second half of the 14th century. This makes it one of the oldest man-made ditches in the Erzgebirge mining region. In the 19th century, the man-made ditch provided water for the local textile industry. The pipe trench provided water for tin processing until the cessation of mining in Ehrenfriedersdorf in 1990, making it one of Germany’s oldest man-made ditches still in operation. The pipe trench was repaired between 1999 and 2002.
