ALVIGNANO_IMPIANTO_LOCALITA_MAZZAMAURO is a wastewater treatment plant located in Rasignano, Alvignano, in the province of Caserta, Campania, Italy. The plant serves a population of approximately 3,450 people, classifying it as a small agglomeration under Italian and EU regulations. It operates with a designed capacity of 3,500 cubic meters per day and discharges an average volume of 682.98 m³/day. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size discharging into freshwater or estuaries. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant's capacity utilization appears moderate, indicating it is not overloaded. The treated effluent is discharged into local watercourses within the Volturno River basin, which ultimately flows into the Tyrrhenian Sea. The plant plays a key role in protecting the water quality of the region's rivers and the downstream marine environment. By removing pollutants, it helps safeguard aquatic ecosystems and supports the ecological health of the Campania region.

The plant discharges into the Volturno River basin, which drains into the Tyrrhenian Sea. The Volturno River is the longest river in southern Italy and supports diverse aquatic life, including fish species such as trout and eel. The downstream coastal area includes important marine habitats. Secondary treatment helps reduce nutrient loading, which is critical to prevent eutrophication in the sensitive Mediterranean coastal zone.
