Overview
Hvar wastewater treatment plant serves Grad Hvar on the island of Hvar, Croatia. It provides primary treatment with a designed capacity of 25,000 m³/day and discharges near the Adriatic coast.
The Hvar wastewater treatment plant is located in Vira, near the town of Grad Hvar on the island of Hvar, Croatia. It serves the local population and tourist influx on this Adriatic island. The plant has a designed capacity of 25,000 cubic meters per day, reflecting the seasonal demand from tourism. The plant provides primary treatment, which involves physical sedimentation to remove solids. As a coastal facility, it operates under Croatian regulations aligned with the EU Urban Waste Water Treatment Directive (91/271/EEC). For sensitive coastal areas, the directive typically requires more advanced treatment, but primary treatment may be permitted in less sensitive marine environments with adequate dispersion. The treated effluent is discharged into the Adriatic Sea, a semi-enclosed sea with limited water exchange. The surrounding marine environment supports diverse ecosystems, including seagrass meadows and fish nurseries. Proper treatment is essential to prevent nutrient enrichment and protect coastal water quality, which is vital for tourism and local fisheries.
Environmental context
The plant discharges into the Adriatic Sea near the island of Hvar. The Adriatic is a semi-enclosed sea with slow water circulation, making it sensitive to nutrient inputs. The coastal waters support seagrass habitats and marine biodiversity. Effective wastewater treatment helps prevent eutrophication and protects the ecological health of this popular tourist destination.
