OSSI_LOC_S_ERIMU Wastewater Treatment Plant, Ossi, Sardinia, Italy

OSSI_LOC_S_ERIMU is a wastewater treatment plant located in Ossi, in the Sardinia region of Italy. The plant serves a population of approximately 5,885 residents, placing it in the small agglomeration category under Italian and EU regulations. Its location near the coast underscores the importance of effective wastewater management to protect marine ecosystems. As a plant serving a small population, it is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment before discharge. Italian plants of this scale typically employ secondary treatment or equivalent to meet regulatory standards. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating a modest scale. The plant discharges into the local watershed, which ultimately drains into the Mediterranean Sea. Given its proximity to the coast (within 10 km), the treated effluent must meet stringent quality standards to prevent nutrient enrichment and protect coastal habitats. The surrounding area features a Mediterranean climate with seasonal rainfall, influencing flow patterns and treatment requirements.

The plant is located in the Sardinia region, near the city of Sassari. Its treated effluent flows into local watercourses that drain into the Mediterranean Sea, specifically the Gulf of Asinara. This coastal area supports diverse marine life, including seagrass meadows and fish nurseries, which are sensitive to nutrient pollution. Effective treatment is essential to maintain water quality and ecological balance in this semi-arid region where water resources are limited.
