MOLINO_GRZ_DEP Wastewater Treatment Plant, Grottazzolina, Italy

MOLINO_GRZ_DEP is a municipal wastewater treatment plant located in Grottazzolina, in the province of Fermo, Marche region, Italy. The plant serves a population of approximately 1,966 people and is an essential part of the local sanitation infrastructure. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 2,000 m³/day and an average daily discharge of 629.65 m³/day, the plant operates well within its capacity, ensuring effective treatment of wastewater from the community. The treated effluent is discharged into local watercourses that ultimately drain into the Adriatic Sea. The plant plays a crucial role in protecting the water quality of the surrounding environment, including the coastal waters of the Adriatic, which support diverse marine life and are important for tourism and fisheries in the region.

The plant discharges treated wastewater into local streams that flow into the Adriatic Sea, a semi-enclosed sea with limited water exchange. The Adriatic Sea supports important fisheries and tourism along the Italian coast. The plant's secondary treatment helps reduce organic pollutants and nutrients, mitigating the risk of eutrophication in coastal waters. The region's watershed is part of the Marche river system, which drains the Apennine mountains and contributes to the ecological health of the Adriatic basin.
