S_GIOVANNI_NORD_CASCINA_RINALDI Wastewater Treatment Plant, San Giovanni al Natisone, Italy

S_GIOVANNI_NORD_CASCINA_RINALDI is an advanced wastewater treatment plant located in the municipality of San Giovanni al Natisone (San Zuan dal Nadison) in the Friuli-Venezia Giulia region of northeastern Italy. The plant serves a population of approximately 4,092 residents, classifying it as a small agglomeration under Italian and EU regulations. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 4,300 m³/day and a current discharge volume of 810.07 m³/day, the facility operates well within its capacity. As an Italian plant, it falls under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires appropriate treatment for discharges into sensitive areas. The treated effluent is discharged into local watercourses that ultimately drain into the Adriatic Sea via the Isonzo (Soča) river system. The plant plays a key role in protecting the region's water quality, supporting both local ecosystems and downstream environments in the northern Adriatic.

The plant discharges into the Judrio River (a tributary of the Isonzo/Soča), which flows into the Gulf of Trieste in the northern Adriatic Sea. This coastal area supports diverse marine life and is an important migratory corridor for fish and birds. Advanced treatment helps minimize nutrient loading, protecting the sensitive Adriatic ecosystem from eutrophication.
