AGUGLIANO_SUD_LATO_POLVERIGI_DEP - Closed Advanced Wastewater Treatment Plant in Polverigi, Marche, Italy

AGUGLIANO_SUD_LATO_POLVERIGI_DEP is a former wastewater treatment plant located in Polverigi, a town in the province of Ancona, Marche region, Italy. The plant served the local area and was designed with a capacity of 1,500 cubic meters per day, reflecting its role in managing municipal wastewater for a small community. It is now closed, and its operational history is part of the region's wastewater infrastructure evolution. As an advanced treatment facility, the plant was equipped to provide tertiary-level purification, which goes beyond secondary treatment to remove nutrients and other pollutants. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), such treatment is typically required for discharges into sensitive areas or for larger agglomerations. Although the plant is closed, its design capacity suggests it served a population equivalent to a small agglomeration, likely requiring compliance with Italian national regulations implementing the directive. The plant is situated within 10 kilometers of the Adriatic Sea, making its discharge location environmentally sensitive. The treated effluent would have been released into local watercourses that drain into the Adriatic, affecting coastal water quality and marine ecosystems. The Marche region's coastal waters support tourism and fisheries, emphasizing the importance of proper wastewater management to prevent eutrophication and protect biodiversity.

The plant is located near the Adriatic Sea, a semi-enclosed basin with limited water exchange, making it susceptible to nutrient pollution. Treated wastewater from the plant would have entered local streams or drainage channels flowing into the Adriatic, impacting coastal marine habitats. The area supports diverse aquatic life and is important for regional fisheries and tourism. Proper treatment is critical to prevent algal blooms and maintain water quality in this ecologically sensitive coastal zone.
