San Giovanni Suergiu Wastewater Treatment Plant, Sardinia, Italy

The San Giovanni Suergiu wastewater treatment plant is located in the Sulcis Iglesiente region of Sardinia, Italy, serving the municipality of Santu Giuanni Suèrgiu/San Giovanni Suergiu. With a population served of approximately 34,306, it is classified as a medium agglomeration under Italian and EU regulations. As an Italian facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations between 10,000 and 150,000 population equivalent. For sensitive areas, tertiary treatment may be mandated. The plant's location in Sardinia, an island region, means it likely discharges into coastal waters or inland water bodies that eventually reach the Mediterranean Sea. The plant's environmental significance lies in its role protecting the coastal and marine ecosystems of the Sulcis Iglesiente area. The treated effluent likely enters local watercourses that drain into the Mediterranean Sea, supporting the region's biodiversity and tourism economy. Proper treatment is essential to prevent nutrient pollution and protect sensitive marine habitats.

The plant serves the Sulcis Iglesiente area in southwestern Sardinia, where local watercourses drain into the Mediterranean Sea. The region's coastal and marine ecosystems support diverse aquatic life, including seagrass meadows and fish populations. Effective wastewater treatment is critical to prevent eutrophication and maintain water quality in this ecologically sensitive coastal zone.
