Impianto C da Mintina Wastewater Treatment Plant, Serradifalco, Sicily

Impianto C da Mintina is a wastewater treatment plant located in Serradifalco, a town in the province of Caltanissetta, Sicily, Italy. The plant serves a population of approximately 7,000 residents, classifying it as a small to medium agglomeration under Italian and EU regulations. It is situated inland, away from coastal areas, and its operations are part of the regional wastewater infrastructure managed by local authorities. As a plant serving a population of 7,000, it falls under the scope of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. Typical facilities of this scale in Italy employ secondary biological treatment processes to meet national and EU standards. The plant discharges treated wastewater into local water bodies, likely tributaries of the Salso River or other streams in the region, which ultimately drain into the Mediterranean Sea. The surrounding area is characterized by agricultural land and small urban settlements, and the plant plays a key role in protecting local water quality and supporting the ecological health of the watershed.

The plant is located in the interior of Sicily, within the drainage basin of the Salso River, which flows into the Mediterranean Sea near Licata. The region experiences a Mediterranean climate with hot, dry summers and mild, wet winters, leading to seasonal variations in water flow. The treated effluent contributes to the base flow of local streams, supporting aquatic habitats and agricultural water use downstream. The area is not near any designated protected areas, but the receiving waters are ecologically sensitive due to their role in sustaining biodiversity in a semi-arid landscape.
