Jerzu Loc Su Forreddu Wastewater Treatment Plant, Sardinia, Italy

The Jerzu Loc Su Forreddu wastewater treatment plant is situated in the Ogliastra region of Sardinia, Italy, serving the town of Jerzu. With a population equivalent of 5,553, it falls under the EU classification of a small agglomeration. The plant is positioned inland, approximately 9.5 km from the coast, and its treated effluent likely discharges into local watercourses that eventually reach the Tyrrhenian Sea. As a small Italian treatment facility, it is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for inland agglomerations of this size. Italian regional authorities oversee compliance with national regulations implementing the directive. The receiving water body is not explicitly named, but the plant's location in eastern Sardinia suggests discharge into streams flowing toward the Tyrrhenian Sea. The region's Mediterranean climate and coastal proximity mean that treated effluent quality is important for protecting both local freshwater ecosystems and the marine environment. Sardinia's coastal waters support diverse marine life and are important for tourism and fisheries.

The plant discharges into local watercourses that drain into the Tyrrhenian Sea, a basin of the Mediterranean Sea. The region's coastal waters support seagrass meadows and diverse marine species, making nutrient and pollutant control critical. The plant's inland location provides some natural attenuation before discharge reaches the coast, but the proximity to the sea (within 50 km) means that effective treatment is essential to prevent eutrophication and protect sensitive marine habitats.
