Sewage treatment Biberacher Hütte
2012 until 2016
The section Biberach of the German Alpine Club (Deutscher Alpenverein, DAV) runs an alpine hut at 1.846 meters above sea level in the Bregenz Forest. Counting all capacities concerning beds and dormitories (including the emergency dormitory) the hut can host up to 110 people at the same time. During the season (Mid June to mid October) is produces every day 3.500 liter waste water. Until now, these were treated with a 35-year old installation.
The scope of this project was to renew the sewerage facility to reach a state-of-the-art installation. Now, the waste water is first mechanically cleaned (pre-treatment) and then reaches through a buffer an installation using moving-bed technology. After the cleaning process the water is sent to an overgrown soil filter which also serves as emergency filter during a breakdown of the installation. Passing the soil filter the cleaned waste water ends up in a swale and is thus infiltrated into the underground.
