The connection between scientific knowledge and actual needs as well as operational requirements of water supply and wastewater treatment companies was the subject of a stakeholder workshop organized and hosted by EYDAP on October 9th.
The workshop titled “Shaping water cycle in modern urban areas” was dedicated to innovative methods of monitoring, protecting and exploiting water resources, aiming to address the challenges posed by climate change and strengthen urban resilience and sustainability.
The event confirmed once again that management of modern, urban water cycle requires expanded ‘alliances’ and close cooperation of all stakeholders under a common vision: ensuring the adequacy and quality of water in modern cities.

In the context of the workshop, the goals, the technology developed, and the expected outcomes of Theseus H4C were presented with a focus on innovative solutions for water reuse in non-potable applications.
The THESEUS session included three presentations:
- “Reclaimed Water Reuse & Decentralised Water Recovery Systems”, presented by Efthymios Lytras, Deputy Director of Strategy & Innovation, EYDAP.
- “Reuse of Reclaimed Water for Irrigation in Eastern Attica: The Pilot Application at the Koropi–Paiania Wastewater Treatment Plant”: Theodora Paramana, researcher from EYDAP’s R&D dpt. and Argyro Plevri, from the Sanitary Engineering Laboratory of the National Technical University of Athens (NTUA), presented the pilot application, explaining how reclaimed water can support agricultural irrigation in Eastern Attica.
- “A New Approach to Urban Water Recycling: Sewer Mining at Klonaridis–Fix Park”: Klio Monokrousou, from the Urban Water Management and Hydroinformatics Group of NTUA, presented the planned sewer mining application, where decentralised water recovery is intended to provide reclaimed water for irrigating urban green space in a densely urbanised area of Athens.


With more than 60 representatives of the public administration, industry, the academic and research community, municipal companies providing water supply and wastewater treatment services, together with EYDAP executives having attended the workshop, the event turned into a ‘lively’ and dynamic space for the exchange of knowledge, experiences and innovative practices.
During the discussions that followed the presentations, several participants showed particular interest in innovative water reuse solutions for non-potable uses and how these can have a strong social and environmental impact, reaffirming the need for dialogue and collaboration between all stakeholders in designing strategies that will ensure the future of the most valuable resource for our cities.
