It is assumed to be in compliance with local environmental authorities. The plant discharges into the local watershed, which ultimately drains into the Ionian Sea via the surrounding river network. The region of Puglia is characterized by a Mediterranean climate and karstic geology, making groundwater protection a key environmental concern. The treated effluent contributes to the water balance of local streams and supports downstream ecosystems, including coastal habitats along the Ionian coast.
Environmental context
The VILLA CASTELLI plant discharges into the local drainage network that flows toward the Ionian Sea, a semi-enclosed basin of the Mediterranean. The surrounding area features karstic aquifers and seasonal streams, which are sensitive to nutrient loading. The plant's discharge helps maintain base flow in these watercourses, supporting aquatic life and preventing saltwater intrusion in coastal zones.
