Novalja Vrtic Wastewater Treatment Plant - Ličko-senjska županija, Croatia

Novalja Vrtic is a wastewater treatment plant situated in Ličko-senjska županija, Croatia, near the town of Novalja on the island of Pag. The plant serves the local population and has a designed capacity of 14,500 m³ per day, indicating it handles a significant volume of wastewater from the area. The plant provides primary treatment, which involves physical processes such as sedimentation to remove solids. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), primary treatment is generally acceptable for discharges into coastal waters, provided it does not adversely affect the environment. Croatia, as an EU member state, follows this directive, and plants of this scale are expected to meet regulatory standards. The treated effluent is discharged into the Adriatic Sea, a semi-enclosed sea with sensitive marine ecosystems. The plant's proximity to the coast (within 10 km) means its discharge can directly impact coastal water quality, affecting tourism and marine life in the region.

The plant discharges into the Adriatic Sea, which is part of the Mediterranean basin. The Adriatic Sea supports diverse marine life, including seagrass meadows and fish populations, and is an important area for tourism and fisheries. The coastal waters near Novalja are ecologically sensitive, and primary treatment may not fully remove nutrients, potentially contributing to eutrophication in local bays.
