Domus De Maria Loc Su Sfundau Wastewater Treatment Plant, Sardinia, Italy

Domus De Maria Loc Su Sfundau is an advanced wastewater treatment plant located in Domus De Maria, a municipality in the Sardinia region of Italy. The plant serves a population of approximately 2,185 residents, classifying it as a small agglomeration under EU regulations. Its location near the southern coast of Sardinia places it in a coastal environment with sensitive marine ecosystems. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 1,200 cubic meters per day and a discharge volume of 432.55 cubic meters per day, the facility operates well within its capacity. The advanced treatment level likely includes nutrient removal, which is critical for protecting coastal waters from eutrophication. The treated effluent is discharged into the coastal waters of the Mediterranean Sea, specifically near the Gulf of Cagliari. This area supports diverse marine life and is part of the broader Sardinian coastal ecosystem. The plant's advanced treatment helps minimize environmental impact on the local watershed and downstream marine environment, contributing to the preservation of water quality in this ecologically sensitive region.

The plant discharges treated wastewater into the coastal waters of the Mediterranean Sea near the Gulf of Cagliari. This area is ecologically sensitive, supporting seagrass meadows and diverse marine species. The advanced treatment process reduces nutrient loads, helping to prevent eutrophication and protect the health of the coastal marine ecosystem, which is important for local fisheries and tourism.
