CASTELSARDO_LOC_LU_BAGNU Wastewater Treatment Plant, Lu Bagnu, Sardinia

CASTELSARDO_LOC_LU_BAGNU is an advanced wastewater treatment plant located in Lu Bagnu, a frazione of Castelsardo in the province of Sassari, Sardinia, Italy. The plant serves a population of approximately 4,380 and has a designed capacity of 5,000 cubic meters per day, with an average discharge volume of 867.08 cubic meters per day. As an advanced treatment facility, it provides a higher level of pollutant removal beyond secondary treatment, which is typical for plants in sensitive coastal areas under the EU Urban Waste Water Treatment Directive (91/271/EEC). The directive requires appropriate treatment for discharges into sensitive areas, and Sardinia's coastal zones are often designated as such due to tourism and ecological value. The plant is located within 10 km of the coast, and its treated effluent likely discharges into the Mediterranean Sea via local watercourses or directly. This proximity to the sea underscores the importance of advanced treatment to protect marine water quality, bathing areas, and the region's tourism-dependent economy.

The plant is situated on the northwestern coast of Sardinia, near the Gulf of Asinara. Treated wastewater likely flows into the Mediterranean Sea, which supports diverse marine life including seagrass meadows and important fisheries. The coastal waters are ecologically sensitive, and advanced treatment helps minimize nutrient loading and protect water quality for recreational use.
