Overview
STIGLIANO_ZONA_PIP is a secondary treatment plant serving Stigliano, Basilicata, Italy. It operates under EU Urban Waste Water Treatment Directive standards for inland communities.
STIGLIANO_ZONA_PIP is a municipal wastewater treatment plant located in Stigliano, a town in the province of Matera, Basilicata, Italy. The plant provides secondary treatment for the local community, situated in the hilly interior of southern Italy, away from coastal areas. As a secondary treatment facility, the plant meets the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for inland freshwater discharges. For agglomerations of this scale, the directive mandates secondary biological treatment to reduce organic matter and suspended solids, ensuring compliance with European water quality standards. The plant discharges treated effluent into local watercourses that drain toward the Ionian Sea via the Basento or Sinni river systems. These rivers support diverse aquatic life and are important for regional agriculture and ecosystems. The plant's operation helps protect downstream water quality in this ecologically sensitive Mediterranean region.
Environmental context
The plant's treated effluent flows into the Basento or Sinni river basins, which drain the Basilicata region and empty into the Gulf of Taranto in the Ionian Sea. These rivers sustain riparian habitats and are used for irrigation, making nutrient removal critical to prevent eutrophication in coastal waters. The area's Mediterranean climate with seasonal rainfall means consistent treatment is vital for maintaining stream health during dry periods.
