They were the East German population's coal gas reserves until the end of the 1980's: the natrual gas storage facilities of "VEB Verbundnetz Gas" as it was then known. Reunification brought, however, new challenges along with new opportunities. In the 90's, the aging aboveground systems for the facilities were modernized and refitted for use with the considerably cleaner and safer natural gas.
