This project aims at safeguarding the Isonzo-Soča river and its host of tributaries through the treatment of urban waste water. The Isonzo-Soča is a cross-border river with its source in the territory of the Republic of Slovenia at the heart of the Julian Alps, it enters Italy at Solkan (Salcano) and finally flows on the Adriatic Sea. Its hydrographic basin covers a surface of more than 3,400 km2, one third of which in Italian territory. In addition to being an important water resource, the Isonzo-Soča also plays a significant environmental role (as the water habitat of several animal and plant species) and a tourist one too, therefore it must be safeguarded. Three streams flow in the municipality of Remanzacco: Grivò, Malina and Torre, which are interconnected and part of the Isonzo river basin. There are three waste water treatment plants in the municipal territory, one serving the sewage system of the main urban centre and the small villages of Selvis and Orzano, releasing the treated water in the Malina stream; the second serving the sewage system of the village of Ziracco, and releasing the treated water in the Grivò stream; and the third serving the sewage system of the village of Cerneglons, and releasing the treated water in the Torre stream. The project - mainly consisting of waste water purification lines in the plants listed above - intends to transfer to the Italian territory the experience acquired by Slovenian Municipalities that are partners in the framework of similar actions financed under PHARE-CBC Programme ECO-ADRIA 2001, in order to contribute to the protection of the Isonzo-Soča basin in a joint and coordinated manner. It also envisages the organisation of technical meetings with visits to the plants located in Slovenia and in Friuli Venezia Giulia to foster the mutual transfer of know-how, and the promotion and dissemination of the results achieved, to be illustrated on the occasion of special events.
