Overview
Pag wastewater treatment plant serves Grad Pag on Pag Island, Croatia. It provides primary treatment with a designed capacity of 10,000 m³/day and discharges near the Adriatic coast.
The Pag wastewater treatment plant is located in Grad Pag on Pag Island, within the Zadar County of Croatia. The facility serves the local population and is situated in a coastal Mediterranean environment, with the Adriatic Sea as the ultimate receiving water body. The plant has a designed capacity of 10,000 cubic meters per day, reflecting the scale of the community it supports. As a primary treatment facility, Pag plant performs physical sedimentation to remove settleable solids. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size are generally required to achieve at least secondary treatment, especially in sensitive coastal areas. The plant's proximity to the Adriatic Sea (within 10 km of the coast) means that treated effluent is likely discharged into coastal waters, which are ecologically sensitive. The Adriatic Sea supports diverse marine life, including seagrass meadows and fish populations. Proper treatment is critical to prevent nutrient enrichment and protect the local marine ecosystem, which also supports tourism and fisheries in the region.
Environmental context
The Pag plant discharges into the Adriatic Sea, a semi-enclosed basin with limited water exchange, making it sensitive to nutrient inputs. The coastal waters around Pag Island support seagrass habitats and are important for local fisheries and tourism. Effective wastewater treatment is essential to prevent eutrophication and maintain water quality in this ecologically valuable marine environment.
