Santa Cesarea Terme Nuovo Wastewater Treatment Plant, Cerfignano, Puglia

Santa Cesarea Terme Nuovo is a wastewater treatment plant located in Cerfignano, a frazione of Santa Cesarea Terme in the Lecce province of Puglia, Italy. The plant serves a population of 2,787 and has a designed capacity of 9,500 cubic meters per day, with a discharge volume of 673 cubic meters per day. The plant provides secondary treatment, which is the standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. For populations between 2,000 and 10,000, secondary treatment is mandatory, and the plant complies with this regulatory framework. The plant's coastal location means it likely operates under additional scrutiny to protect marine waters. The treated effluent is discharged into the Adriatic Sea, as the plant is within 10 km of the coast. The surrounding area is part of the Salento peninsula, known for its karstic geology and sensitive coastal ecosystems. The discharge contributes to the nutrient load in the Adriatic, which supports diverse marine life and is important for local fisheries and tourism.

The plant discharges treated wastewater into the Adriatic Sea, a semi-enclosed basin connected to the Ionian Sea via the Strait of Otranto. The coastal waters near Santa Cesarea Terme are ecologically sensitive, supporting seagrass meadows and marine biodiversity. The region's karstic geology means groundwater and coastal waters are closely linked, requiring careful management of nutrient discharges to prevent eutrophication.
