Santa Margherita di Pula Condominio Baia degli Asfodeli Wastewater Treatment Plant, Pula, Sardinia

Santa Margherita di Pula Condominio Baia degli Asfodeli is an advanced wastewater treatment plant located in Pula, on the southern coast of Sardinia, Italy. The facility serves a small population of 140 residents and is situated in the Foxi 'e Sali area, near the coast. As an advanced treatment plant, it provides a higher level of purification beyond secondary treatment, ensuring high-quality effluent. Operating under Italian regulations that implement the EU Urban Waste Water Treatment Directive (91/271/EEC), the plant meets stringent standards for small agglomerations in sensitive coastal areas. Advanced treatment is typical for plants in this region to protect marine ecosystems and comply with bathing water quality directives. The treated effluent is discharged into the Mediterranean Sea, given the plant's proximity to the coast. The surrounding area includes the Gulf of Cagliari and the nearby wetlands of the Stagno di Cagliari, an ecologically important habitat for migratory birds and marine life. The plant plays a key role in preserving water quality in this sensitive coastal environment.

The plant discharges into the Mediterranean Sea near the Gulf of Cagliari, a semi-enclosed basin with limited water exchange. The nearby Stagno di Cagliari is a coastal lagoon that supports diverse aquatic life, including fish and bird species. Advanced treatment helps minimize nutrient loading and protects the lagoon's ecological balance, which is vital for local fisheries and tourism.
