ARZACHENA_LOC_MULGIANU is a wastewater treatment plant located in Arzachena, a town in the Gallura region of northeastern Sardinia, Italy. The plant serves a population of about 50,743, placing it in the medium-to-large agglomeration category under Italian and EU regulations. As a plant of this scale in Italy, it is expected to comply with the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum, and tertiary treatment if the receiving waters are sensitive. The plant's discharge likely flows into the Tyrrhenian Sea via local watercourses, given its proximity to the coast (within 50 km). The surrounding area is characterized by a Mediterranean climate and tourism-driven population fluctuations, which can impact wastewater loads. Proper treatment is essential to protect the coastal marine environment and the region's ecological and economic resources.

Environmental context

The plant is situated in northeastern Sardinia, within the Gallura region, and its treated effluent likely drains into the Tyrrhenian Sea via small coastal streams or directly through marine outfalls. The coastal waters support diverse marine life, including seagrass meadows and fish nurseries, making nutrient and pathogen removal critical. The region's tourism industry also relies on clean coastal waters for recreation and fisheries.
