DOMUSNOVAS_LOC_S_ACQUA_SASSA Wastewater Treatment Plant, Domusnovas, Sardinia

DOMUSNOVAS_LOC_S_ACQUA_SASSA is a wastewater treatment plant located in Domusnovas, in the Sulcis Iglesiente region of Sardinia, Italy. The plant serves a very small population of 8, reflecting its role in a rural or remote area. It is situated inland, more than 10 km from the coast, and operates under Italian and EU regulations. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for discharges into freshwater and estuaries. Although the designed capacity is 7,000 m³/day, the actual discharge volume is 1.58 m³/day, indicating low utilization. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into a local water body, likely a stream or river that flows toward the Mediterranean Sea. The plant's location in Sardinia, an island with a Mediterranean climate, means that water resources are seasonally stressed, and proper treatment is essential to protect downstream ecosystems and coastal waters.

The plant discharges into a local watercourse that drains into the Mediterranean Sea, likely via the Cixerri or similar river system in southern Sardinia. The region's Mediterranean climate leads to seasonal low flows, making the receiving water body sensitive to nutrient loading. Proper secondary treatment helps prevent eutrophication and protects aquatic life in the downstream coastal zone, which supports diverse marine habitats and fisheries.
