Description

Construction of primary sedimentation and first aeration basin of Vienna's main sewage treatment plant as well as anaerobic sludge stabilisation of the total incoming sludge to extract and process sewage gas in a block heating works.

Objectifs

The objective of this new project is to ensure the energy autarchy of Vienna’s wastewater treatment plant by using sewage sludge as an energy resource for in-house energy needs. With this project, 20 million m3 of methane are expected to be extracted annually from sewage sludge and converted into electricity and heat. This will allow Vienna’s wastewater treatment plant to cover 100% of its own electricity needs from renewable sources by 2020 and to reduce its energy costs at the same time.
