Overview
CASTELGRANDE_VIGNALI is a secondary wastewater treatment plant serving 300 people in Castelgrande, Basilicata, Italy. It discharges 59.39 cubic meters of treated wastewater daily.
CASTELGRANDE_VIGNALI is a wastewater treatment plant located in Castelgrande, a small town in the Basilicata region of southern Italy. The plant serves a population of approximately 300 people, reflecting its role in a small rural community. It operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for collection and treatment of wastewater. The plant provides secondary treatment, a biological process that removes organic matter and suspended solids. It has a designed capacity of 300 cubic meters per day and currently treats an average daily flow of 59.39 cubic meters, indicating it operates well below capacity. This scale is typical for small agglomerations, where secondary treatment is the minimum required by EU regulations for inland freshwater discharges. The treated effluent is discharged into local watercourses that eventually drain into the Tyrrhenian Sea via the Sele River basin. The surrounding area is characterized by mountainous terrain and agricultural land, making the plant's role in protecting local streams from nutrient pollution important for maintaining water quality and supporting downstream ecosystems.
Environmental context
The plant discharges into small streams in the Basilicata region, which are part of the Sele River basin. The Sele River flows westward into the Tyrrhenian Sea near the Gulf of Salerno. The watershed supports diverse aquatic life and is used for irrigation, making the plant's secondary treatment essential to prevent eutrophication and protect downstream habitats.
