Carpignano Salentino Wastewater Treatment Plant | Puglia, Italy

The Carpignano Salentino wastewater treatment plant is located in the Puglia region of southern Italy, serving the town of Carpignano Salentino in the province of Lecce. The plant is situated near the Adriatic coast, within 50 km of the shoreline, and serves a population of approximately 6,239 residents. As a small agglomeration, it falls under the regulatory framework of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for inland discharges and more stringent treatment for sensitive areas or coastal zones. The plant's designed capacity of 1.00 indicates a relatively small facility. Under Italian implementation of the EU directive, plants serving populations between 2,000 and 10,000 are typically required to provide secondary treatment, with possible tertiary treatment if discharging into sensitive areas. The plant's proximity to the Adriatic Sea may influence its treatment requirements to protect coastal water quality. The treated effluent from the plant likely discharges into local watercourses that flow into the Adriatic Sea, part of the Ionian Sea basin. The receiving environment supports diverse marine life and is important for regional tourism and fisheries. Proper wastewater treatment is essential to prevent eutrophication and protect the coastal ecosystem, which includes seagrass meadows and nursery habitats for fish.

The plant is located in the Salento peninsula, a karstic region where surface waters are limited and groundwater is vulnerable. Treated wastewater likely infiltrates or discharges into small streams that eventually reach the Adriatic Sea. The coastal waters support seagrass meadows and are important for local fisheries and tourism. Protecting these waters from nutrient pollution is critical to maintain ecological balance and water quality.
