CASTELGRANDE_CAMPESTRE Wastewater Treatment Plant, Castelgrande, Basilicata

CASTELGRANDE_CAMPESTRE is a municipal wastewater treatment plant located in the Campestre area of Castelgrande, a small town in the province of Potenza, Basilicata, Italy. The plant serves a population of 80 and has a designed capacity of 300 cubic meters per day, indicating it is sized for modest local demand. The plant provides secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this scale. Secondary treatment typically involves biological oxidation and sedimentation to reduce organic matter and suspended solids before discharge. The treated effluent is discharged into local watercourses that drain into the Basilicata region's river network, eventually reaching the Ionian Sea. The plant plays a role in protecting the local watershed and downstream aquatic ecosystems from untreated wastewater pollution.

The plant discharges into small streams in the Basilicata region, which flow into the Ofanto River basin and ultimately reach the Ionian Sea. The downstream environment supports diverse aquatic life and is important for regional biodiversity. The area's hilly terrain and agricultural land use make proper wastewater treatment essential to prevent nutrient enrichment and protect water quality.
