The Umag wastewater treatment plant is located in the town of Umag, on the Istrian Peninsula in Croatia, along the Adriatic coast. The plant has a designed capacity of 20,000 cubic meters per day and provides primary treatment for municipal wastewater. As a coastal plant in Croatia, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires at least secondary treatment for discharges into sensitive areas like the Adriatic Sea. The treated effluent is discharged into the Adriatic Sea, a semi-enclosed marine environment that is ecologically sensitive and supports diverse marine life. The plant plays a key role in protecting the coastal waters of Istria, which are important for tourism and fisheries.
