Overview
Marina di Altidona PDS DEP is a secondary treatment plant in Pedaso, Marche, Italy, serving 6,504 people with a designed capacity of 9,000 m³/day and a discharge volume of 953.44 m³/day.
Marina di Altidona PDS DEP is a wastewater treatment plant located in Pedaso, within the Marche region of Italy. It serves a population of approximately 6,504 people, placing it in the small-to-medium agglomeration category under Italian and EU regulations. The plant is situated near the Adriatic coast, less than 10 km from the shoreline, which influences its discharge considerations. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size discharging into coastal waters. It has a designed capacity of 9,000 m³/day and currently treats an average daily flow of 953.44 m³/day, indicating significant spare capacity. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. Treated effluent is discharged into the Adriatic Sea, a semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution. The plant's location in the Valdaso area, near the Aso River valley, means its discharge contributes to the overall nutrient load in the coastal zone. Proper treatment helps protect marine ecosystems and supports tourism and fisheries in the region.
Environmental context
The plant discharges into the Adriatic Sea, a semi-enclosed basin that receives inflows from numerous rivers along the Italian coast. The local watershed includes the Aso River, which flows through the Marche region before reaching the sea. The Adriatic Sea supports diverse marine life and is an important area for fishing and tourism. Nutrient inputs from wastewater can contribute to eutrophication, so secondary treatment helps mitigate this risk. The coastal zone is also ecologically sensitive, with seagrass meadows and fish nursery habitats that benefit from controlled discharges.
