Montappone Saletto Spiazzi Dep Wastewater Treatment Plant, Montappone, Italy

Montappone Saletto Spiazzi Dep is an advanced wastewater treatment plant located in the municipality of Montappone, in the Fermo province of the Marche region, Italy. The plant serves a population of 773, classifying it as a small agglomeration under Italian and EU regulations. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 700 cubic meters per day and an actual discharge volume of 153.03 cubic meters per day, the plant operates well within its capacity, ensuring effective treatment of local wastewater. The treated effluent is discharged into the local watershed, which ultimately drains into the Adriatic Sea via the Tenna River basin. The plant plays a key role in protecting the water quality of the Tenna River and the coastal environment of the Adriatic Sea, supporting aquatic life and recreational uses downstream.

The plant discharges into the Tenna River basin, which flows eastward into the Adriatic Sea. The downstream environment includes the coastal waters of the Adriatic, a semi-enclosed sea with sensitive ecosystems such as seagrass meadows and fish nursery areas. The plant's advanced treatment helps reduce nutrient loading, mitigating eutrophication risks in the Adriatic.
