| dc.description.abstract | With the aim to address water scarcity and support the sustainable use and treatment of (waste-) water, this study examines a self-sufficient, off-grid water system in the inhabited demonstration house “KREIS-Haus”. The water system is based on rainwater harvesting and greywater treatment with a low-tech treatment implementing submerged, attached biofilm growth. Treated rainwater is used as drinking water and treated greywater is used for the washing machine and irrigation of the rooftop garden. In an experimental period of 17 weeks, several water quality parameters were analyzed once per week before and after the rainwater and greywater treatment. Comparing the results to Swiss/EU regulation and literature, the treated greywater is suitable for irrigation and laundry. However, the treated rainwater did not always meet the required limit values for turbidity and TOC. The greywater treatment unit achieved removal rates of 92% for COD and 98% for turbidity, and no accumulation of substances was observed in the treated greywater. Water self- sufficiency was at 100% over the whole experimental period, and excess water pumped out of the system met the standard for discharge into a water body. While these first results indicate a promising approach to the water concept, more long-term monitoring and testing with higher occupancy is needed. | de_CH |
