Overview
Sanza Impianto Localita Petraro is a secondary wastewater treatment plant serving approximately 2,950 people in Sanza, Campania, Italy. It has a designed capacity of 3,000 m³/day and discharges 584 m³/day.
Sanza Impianto Localita Petraro is a municipal wastewater treatment facility located in Sanza, a town in the province of Salerno, Campania, Italy. The plant serves a population of approximately 2,950 residents, placing it in the small agglomeration category under Italian and EU regulations. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for inland freshwater discharges from agglomerations of this size. With a designed capacity of 3,000 m³/day and an average daily discharge of 584 m³/day, the facility operates well below its capacity, indicating headroom for future growth or seasonal variations. The treated effluent is discharged into the local watershed, which ultimately drains into the Tyrrhenian Sea via the Bussento River or nearby coastal streams. The region's karst topography and proximity to the Cilento and Vallo di Diano National Park underscore the importance of maintaining high treatment standards to protect both groundwater and downstream aquatic ecosystems.
Environmental context
The plant discharges into the Bussento River basin, which flows through the Cilento region before reaching the Tyrrhenian Sea. This coastal area supports diverse marine life and is part of a ecologically sensitive Mediterranean ecosystem. The karst geology of the area means groundwater and surface water are closely connected, making pollution control critical for both human use and biodiversity.
