Planning of Decentralized Greywater Treatment and Reuse

This dissertation project in the field of ecological engineering examines the sustainability of decentralized greywater treatment and reuse in buildings in Switzerland. The focus is on determining under what conditions such systems can help conserve drinking water and make buildings more resilient to climate change.

To this end, various approaches are systematically compared. Using a multi-criteria analysis (MCDA), advantages and disadvantages are identified, and trade-offs between environmental impact, costs, and technical implementation are clearly presented.

The results are intended to support planners and decision-makers in making informed assessments and implementing decentralized water systems.
