DESCRIPTION:Marios S. Kyriakou\, Ioannis Chrysostomou\, Stelios G. Vrachimi
 s\, Konstantinos Papadopoulos\, Demetrios G. Eliades \nKIOS Research and I
 nnovation Center of Excellence\, University of Cyprus\n\nWater losses in d
 istribution networks remain a major challenge for utilities worldwide. App
 roximately 30% of water is classified as non-revenue water\, while around 
 22% corresponds to real losses. To reduce real losses\, pressure managemen
 t is applied. In recent years\, we have developed the OCEANOS Digital Twin
 \, an integrated platform that uses QGIS as the interface for visualizing 
 and processing data. The platform connects to a backend system that proces
 ses different data layers and models. It uses GIS information\, such as el
 evations and pipe networks\, to create a hydraulic model. In addition\, it
  incorporates sensor data (flow\, pressure) and smart meter data to solve 
 an optimization problem that estimates flows and pressures. We designed a 
 system that helps operators identify how much they can reduce pressure whi
 le considering building heights obtained from open data. This approach ens
 ures that service levels remain unaffected. The methodology was tested in 
 Limassol and Larnaca. The pressure estimates were validated using availabl
 e measurements. Preliminary results showed that\, in Larnaca\, it was poss
 ible to achieve a reduction in real losses while maintaining adequate serv
 ice conditions. This work presents the technical solution developed within
  QGIS and demonstrates how the OCEANOS Digital Twin supports pressure mana
 gement strategies for leakage reduction.\n\nAcknowledgments\nThe work was
