Vrgorac Wastewater Treatment Plant, Grad Vrgorac, Croatia

The Vrgorac wastewater treatment plant is located in the town of Vrgorac, within the Split-Dalmatia County of southern Croatia. It serves the local population of Grad Vrgorac as part of the region's municipal wastewater infrastructure. The plant is situated inland, approximately 50 kilometers from the Adriatic coast. The facility operates with secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this scale. The designed capacity of 5,000 cubic meters per day indicates it serves a medium-sized community. As Croatia is an EU member state, the plant must comply with EU regulations for wastewater treatment and discharge. The treated effluent from the Vrgorac plant is discharged into local watercourses that eventually drain into the Adriatic Sea. The plant plays a key role in protecting the downstream environment, including the Neretva River basin and the coastal waters of the Adriatic, which support diverse marine life and are important for tourism and fisheries.

The Vrgorac plant discharges into local streams that flow toward the Neretva River, one of Croatia's largest rivers, which empties into the Adriatic Sea near the Neretva Delta. This delta is an ecologically sensitive area that supports diverse aquatic life and serves as an important migratory corridor for birds. The secondary treatment provided by the plant helps reduce nutrient and organic pollution, protecting downstream water quality and the coastal marine environment.
