Rotondella Trisaia is a municipal wastewater treatment plant located in Rotondella, in the province of Matera, Basilicata, Italy. It serves a population of approximately 3,250 residents, classifying it as a small agglomeration under Italian and EU regulations. The plant is situated near the Ionian Sea coast, within 10 km of the shoreline. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for discharges into coastal waters from agglomerations of this size. Its designed capacity is 5,000 m³/day, and it currently treats an average daily flow of 643.39 m³/day, indicating ample reserve capacity. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into the local coastal environment, likely via a nearby stream or directly into the Ionian Sea. The receiving waters are part of the Gulf of Taranto, an important marine ecosystem supporting fisheries and biodiversity. The plant plays a key role in protecting coastal water quality and preventing eutrophication in the sensitive Mediterranean marine environment.
Environmental context
The plant discharges into the Ionian Sea via the Gulf of Taranto, a semi-enclosed basin with limited water exchange. This coastal area supports diverse marine life, including seagrass meadows and fish nurseries. The secondary treatment helps reduce nutrient loads, mitigating the risk of algal blooms and oxygen depletion in the coastal zone.
