CRETONI_MSP_DEP Wastewater Treatment Plant, Monsampolo del Tronto, Marche, Italy

CRETONI_MSP_DEP is a municipal wastewater treatment plant located in San Francesco, Monsampolo del Tronto, in the Marche region of Italy. The plant serves a small population of 215 people and operates with secondary treatment, a standard level for small agglomerations under Italian regulations. With a designed capacity of 300 m³/day and a current discharge volume of 33.89 m³/day, the plant operates well below its capacity. As an Italian facility, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for inland plants serving between 2,000 and 10,000 population equivalents, though smaller plants may have different requirements. The plant is situated less than 10 km from the Adriatic Sea, making its discharge potentially influential on coastal water quality. The treated effluent likely flows into local watercourses that drain into the Adriatic, supporting the marine ecosystem of the central Adriatic coast.

The plant discharges into the local watershed of the Marche region, which drains into the Adriatic Sea. The Adriatic is a semi-enclosed sea with limited water exchange, making it sensitive to nutrient inputs. The plant's secondary treatment reduces organic load but may not fully remove nutrients, which could contribute to eutrophication in coastal areas. The surrounding area includes agricultural and urban land uses, adding diffuse pollution pressures.
