Supersano Wastewater Treatment Plant: Serving Supersano, Puglia, Italy

The Supersano wastewater treatment plant is located in the Puglia region of southern Italy, serving the town of Supersano and surrounding areas. With a population equivalent of 13,529, it is a medium-sized agglomeration under Italian and EU regulations. The plant is situated inland, approximately 50 km from the coast, and discharges treated effluent into local watercourses that eventually reach the Ionian Sea. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant has a designed capacity of 20,376 m³/day, indicating it can handle peak flows and future growth. The discharge volume is 515 m³/day, suggesting current flows are well within capacity. The treated effluent from Supersano flows into local streams and rivers that drain into the Ionian Sea. This coastal region supports diverse marine life and is important for tourism and fisheries. Proper treatment helps protect the sensitive coastal ecosystem from nutrient pollution and pathogens, maintaining water quality for recreational and economic uses.

The Supersano plant discharges into local watercourses that drain into the Ionian Sea, a semi-enclosed basin of the Mediterranean. The Ionian Sea supports diverse marine ecosystems, including seagrass meadows and fish nurseries. The region's coastal waters are used for tourism and fishing, making nutrient and pathogen control critical. Secondary treatment reduces organic load and suspended solids, helping to prevent eutrophication and protect downstream habitats.
