OTTANA T A S is a wastewater treatment plant located in Ottana, in the province of Nuoro, Sardinia, Italy. The plant serves a population equivalent of around 92,066, classifying it as a large agglomeration under EU regulations. It is situated inland, away from the coast, and its operations are part of the regional wastewater infrastructure for central Sardinia. As a large agglomeration, the plant is expected to meet the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment as a minimum, and possibly tertiary treatment if the receiving waters are sensitive. The plant's scale implies a robust treatment system to comply with Italian and EU standards. The plant discharges treated wastewater into local watercourses that eventually drain into the Tirreno Sea. The surrounding region features a Mediterranean climate with seasonal rainfall, and the plant plays a key role in protecting local water quality and downstream ecosystems, including the coastal marine environment.
Environmental context
The plant is located inland in central Sardinia, and its treated effluent likely flows into the Tirso River basin or nearby streams, eventually reaching the Tyrrhenian Sea. The downstream environment includes agricultural areas and coastal zones that support diverse aquatic life. Protecting these waters from nutrient pollution is critical for maintaining ecological balance and preventing eutrophication in the coastal marine ecosystem.
