The 2026 edition of the UrbanWaterSECURITY Symposium forms part of the broader UrbanWaterSECURITY initiative and is shaped within a well-established framework of scientific, educational and territorial cooperation. Organised by the Sanitary Environmental Engineering Division (SEED) at the University of Salerno, and co-organised with a distinguished network of international academic partners and the Archaeological Park of Pompeii, the Symposium reflects a shared commitment to interdisciplinary dialogue, institutional collaboration and global engagement. Its profile is further reinforced by the auspices of leading scientific and academic organisations, confirming its recognised relevance across research, higher education and international cooperation.
