BONO_LOC_BICOLEDDU Wastewater Treatment Plant, Bono, Sardinia

BONO_LOC_BICOLEDDU is an advanced wastewater treatment plant located in Bono, a town in the province of Sassari, Sardinia, Italy. The plant serves a population of around 3,900 residents and has a designed capacity of 5,000 cubic meters per day, with a current discharge volume of about 773 m³/day. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). Italy implements this directive through national regulations, requiring advanced treatment in sensitive areas like parts of Sardinia to protect water quality. The plant discharges treated wastewater into local watercourses that ultimately drain into the Tyrrhenian Sea. Sardinia's Mediterranean climate and the region's ecological significance, including coastal and marine habitats, underscore the importance of advanced treatment in preserving downstream water quality and supporting biodiversity.

The plant's treated effluent flows into small streams in the Tirso River basin, which drains into the Tyrrhenian Sea. Sardinia's watersheds support diverse aquatic life and are important for migratory birds. The advanced treatment helps protect downstream ecosystems from nutrient pollution, which is critical given the region's sensitive coastal and marine environments.
