Golfo Aranci Wastewater Treatment Plant, Figari/Golfo Aranci, Sardinia

The Golfo Aranci wastewater treatment plant is situated in the Figari/Golfo Aranci area of Sardinia, Italy, within the Gallura Nord-Est Sardegna region. It serves a population of approximately 15,236 people, classifying it as a medium-sized agglomeration under Italian and EU regulations. The plant is located near the coast, within 50 kilometers of the Tyrrhenian Sea. As an Italian wastewater facility, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size discharging into coastal waters. The regulatory framework ensures that treated effluent meets standards for protecting the marine environment. The plant discharges into the Tyrrhenian Sea, a major basin of the Mediterranean Sea. The coastal waters of Sardinia support diverse marine life, including seagrass meadows and fish populations. Proper treatment is essential to prevent nutrient pollution and protect the ecological health of the surrounding marine environment, which is important for tourism and local fisheries.

The plant discharges into the Tyrrhenian Sea, part of the Mediterranean Sea, which is a semi-enclosed basin with limited water exchange. The coastal waters near Golfo Aranci support sensitive marine habitats, including Posidonia oceanica seagrass meadows, which are crucial for biodiversity and carbon sequestration. Nutrient inputs from wastewater must be carefully managed to avoid eutrophication and algal blooms that could harm these ecosystems.
