Case Bianche PTP DEP - Advanced Wastewater Treatment in Potenza Picena, Marche

Case Bianche PTP DEP is an advanced wastewater treatment plant located in Potenza Picena, in the Marche region of Italy. The facility serves a population of approximately 4,781 residents and is situated near the Adriatic coast. As a small-scale municipal plant, it plays a key role in managing local wastewater within the Potenza Picena area. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 5,000 m³/day and a reported discharge volume of 946.47 m³/day, the plant operates well within its capacity. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), Italian plants serving agglomerations of this size are required to provide secondary treatment, and the advanced level here indicates compliance with stricter standards for sensitive areas. The treated effluent is discharged into the local water system, ultimately reaching the Adriatic Sea. The Marche region's coastal waters support diverse marine life and are important for tourism and fishing. By providing advanced treatment, the plant helps protect the ecological health of the Adriatic coastal zone from nutrient pollution and other contaminants.

The plant discharges into local watercourses that drain into the Adriatic Sea, a semi-enclosed basin with limited water exchange. The Adriatic coast of Marche supports seagrass meadows, fish nurseries, and migratory bird habitats. Advanced treatment reduces nutrient loads, helping to prevent eutrophication and algal blooms in this ecologically sensitive marine environment.
