Campomarino Contrada Marinelle Wastewater Treatment Plant, Campomarino, Molise

The Campomarino Contrada Marinelle wastewater treatment plant is a municipal facility located in Campomarino, in the Molise region of southern Italy. It serves a population of approximately 34,028 people, classifying it as a medium agglomeration under EU regulations. The plant is situated near the Adriatic coast, within 50 km of the shoreline, which influences its environmental management requirements. As a plant serving a population equivalent of over 10,000, it is subject to the EU Urban Waste Water Treatment Directive 91/271/EEC. This directive mandates secondary treatment as a minimum, and for discharges into sensitive areas or coastal zones, more advanced treatment may be required. The designed capacity of the plant is 1.00 (likely in thousands of cubic meters per day or similar unit), indicating a facility sized to handle the local population's wastewater load. The treated effluent from the plant is discharged into the local watershed, which ultimately drains into the Adriatic Sea. The Adriatic Sea is a semi-enclosed basin with sensitive ecosystems, including seagrass meadows and diverse marine life. Proper treatment is essential to prevent nutrient enrichment and protect coastal water quality, supporting tourism and fisheries in the region.

The plant discharges into the local watershed that flows into the Adriatic Sea, a semi-enclosed basin with limited water exchange. The Adriatic Sea supports diverse marine ecosystems, including seagrass beds and important fish spawning grounds. Nutrient loading from wastewater can lead to eutrophication, so effective treatment is critical for maintaining ecological balance and supporting local fisheries and tourism.
