URI_LOC_SA_MANDRA Wastewater Treatment Plant, Uri, Sardinia

URI_LOC_SA_MANDRA is an advanced wastewater treatment plant located in Uri, a town in the province of Sassari on the island of Sardinia, Italy. The plant serves a population of approximately 3,050 people and has a designed capacity of 3,100 cubic meters per day, with an average discharge volume of 603.79 m³/day. It operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for small agglomerations. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. This level of treatment is typical for sensitive areas or where effluent is discharged into ecologically important water bodies. The plant's capacity utilization is low, indicating it operates well within its design limits. The treated effluent is discharged into local watercourses that drain into the Mediterranean Sea. Sardinia's watersheds are characterized by seasonal flows and support diverse aquatic ecosystems. The advanced treatment helps protect downstream water quality and marine habitats from nutrient pollution.

The plant discharges into local streams that flow toward the Mediterranean Sea, which receives waters from the Sardinian watershed. The region's aquatic ecosystems include coastal lagoons and seagrass meadows that are sensitive to nutrient enrichment. Advanced treatment reduces the risk of eutrophication and supports the ecological health of downstream marine environments.
