In search of a suitable location:
Ten locations were investigated from 1976 to 1990 by the team of the Castlunger engineering office (Bruneck), which was responsible for planning and site management. None of these sites were accepted by the population. Since the Middle Pustertal catchment area with its numerous tourists could no longer afford to pollute the River Rienz (which runs through the entire Pustertal), the idea was born to construct the Association Wastewater Treatment Plant Middle Pustertal as a cavern plant.
