Description of project

The Reinhalteverband Hallstaettersee realised the enlargement and modification of the sewerage treatment plant in the year 2022. Our office was entrusted with the structural planning of the refurbishment works as well as the verification statics for the digester tower.

At the sewerage treatment plant Hallstaettersee the new building of the cloudy water treatment/storehouse and rake building/grit chamber was executed. Conversion works took place at the sludge treatment building, rake building and at the pump station. A primary sedimentation basin was rebuilt into a triple-A-basin to raise capacities of the existing facilities.
