Die Partnerländer Schweden, Dänemark, Litauen, Lettland, Polen und Deutschland integrieren in WaterMan die Wasserwiederverwendung als ein neues Element des Wassermanagements, pilotieren Anwendungsbeispiele und bauen umfangreiche Kapazitäten auf lokaler Ebene auf.

Poster presented at the IWA Leading Edge Technologies Conference in Essen, Germany in June 2024

Addressing Europe's current challenges of aging sewer networks, the presented research focuses on the uncertainties in service life and aging behavior of the most used renovation technique, Cured in Place Pipe (CIPP) lining. Examining its aging behavior, common defects and deficiencies were analyzed through literature review and expert interviews. The findings influenced the proposition of a calibration setting for a deterioration model using survival curves. Identified defects stress the need for precise installation and curing processes. The study recommends a thorough review of the initially specified 50-year service life, acknowledging uncertainties during the installation process.

Der Klimawandel stellt die Wasserwirtschaft vor immer größere Herausforderungen, insbesondere in West- und Südeuropa aufgrund lang anhaltender Dürren. Wie Abwasser im Sinne der Kreislaufwirtschaft als Ressource genutzt werden kann, zeigt ein Unternehmen aus Lleida.

Highlights

• The open source model ABIMO allows for a simple calculation of the urban water balance.

• The deviation from the annual natural water balance can be used to detect hotspots for WSUD.

• Transferability of ABIMO is currently tested between the German cities of Berlin and Cologne.
