Geremeas Calaserena Village Wastewater Treatment Plant, Maracalagonis, Sardinia

Geremeas Calaserena Village is a wastewater treatment plant located in the Maracalagonis area of Sardinia, Italy, serving a population of approximately 2,000 residents. The plant is situated along Strada Provinciale 17 di Villasimius in the Solanas locality, within the Cagliari metropolitan region. As a facility designed for a capacity of 2,000 cubic meters per day, it plays a key role in managing domestic wastewater for this coastal community. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. The plant's discharge volume is approximately 396 cubic meters per day, indicating efficient operation relative to its designed capacity. The treated effluent is discharged into the local environment near the Sardinian coastline, ultimately reaching the Tyrrhenian Sea. This coastal area supports diverse marine life and is important for tourism and recreation. By providing advanced treatment, the plant helps minimize nutrient loading and protects the ecological health of the nearby coastal waters and beaches.

The plant discharges treated wastewater into the coastal waters of Sardinia, which flow into the Tyrrhenian Sea. This region features a Mediterranean climate with seasonal rainfall, and the coastal zone supports seagrass meadows and fish nurseries. Advanced treatment reduces nutrient inputs, helping to prevent eutrophication and maintain water quality for sensitive marine habitats.
