Welcome to ARA PUSTERTAL AG

Clean Water - Clean Environment

We operate the five sewage treatment plants, the main collector in Pustertal and the sewage sludge drying and incineration plant on behalf of the Pustertal Wastewater Consortium.
We treat the wastewater of the entire Pustertal Valley, dispose of the residues and thus ensure that our domestic waters are kept clean.

On our homepage, we would like to give you an insight into our work and give you extensive information about our water, waste water and the disposal of sewage sludge.
