MARINO_ASC_DEP Wastewater Treatment Plant, Ascoli Piceno, Marche, Italy

MARINO_ASC_DEP is a wastewater treatment plant located in Ascoli Piceno, in the Marche region of Italy. It serves a population of approximately 38,209 people, placing it in the medium agglomeration category under EU classification. The plant is situated inland, away from coastal areas, and its operations are part of the regional wastewater infrastructure managed by local authorities. The plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size, the directive requires secondary treatment as a minimum, with tertiary treatment in sensitive areas. The designed capacity of 1.00 suggests a moderate-scale facility, though further operational data is not disclosed. The plant discharges treated wastewater into local watercourses that ultimately drain into the Adriatic Sea via the Tronto River basin. The Marche region's rivers support diverse aquatic life and are important for irrigation and recreation. Proper treatment ensures that downstream ecosystems and coastal waters are protected from nutrient pollution and other contaminants.

The plant's treated effluent flows into the Tronto River basin, which drains into the Adriatic Sea. The Adriatic Sea is a semi-enclosed basin with sensitive ecosystems, including seagrass meadows and fish nurseries. Nutrient loading from inland sources can contribute to eutrophication in coastal areas, making effective wastewater treatment critical for maintaining water quality and biodiversity in the region.
