SILANUS_LOC_CRABIELLE Wastewater Treatment Plant, Silanos, Sardinia

SILANUS_LOC_CRABIELLE is a wastewater treatment plant located in the municipality of Silanos/Silanus, in the province of Nuoro, Sardinia, Italy. The plant serves a population of approximately 2,394 people, classifying it as a small agglomeration under Italian and EU regulations. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. The designed capacity is 2,516 m³/day, and the current discharge volume is 473.93 m³/day, indicating operational headroom. The treated effluent is discharged into the local watershed, which ultimately drains into the Tyrrhenian Sea. Sardinia's Mediterranean climate and the region's ecological sensitivity make proper wastewater management essential for protecting coastal water quality and marine ecosystems.

The plant discharges into the local drainage basin of central Sardinia, which flows toward the Tyrrhenian Sea. The receiving waters support diverse aquatic life and are part of a Mediterranean island ecosystem that is ecologically sensitive. Downstream environments include coastal habitats that benefit from well-treated effluent to prevent nutrient enrichment and maintain water quality.
