Wastewater treatment plant for Nin, Privlaka and Vrsi

The scope included design, permitting, construction, supply and installation of equipment, commissioning, trial operation, testing on completion (testing before and during commissioning) and DNP (Defects Notification Period – the period after completion during which the contractor must fix any defects) for the WWTP Grgur, all in accordance with FIDIC (FIDIC – international standard contract conditions for construction and engineering projects) Yellow Book. It also included the construction of 104 km of sewerage network, 34 pumping stations and 31.6 km of water supply rehabilitation.

The project represents a significant milestone for the region, as it increased the share of properly treated wastewater to 83 percent, marking a major leap forward in local infrastructure and environmental stewardship. This improvement has had a direct and positive effect on the quality of life for residents as well as for the many tourists who visit the area each year. By ensuring cleaner coastal waters, healthier ecosystems, and more reliable wastewater services, the project has strengthened both public health and everyday living conditions.

Beyond these immediate benefits, the higher treatment standard has played a crucial role in raising the overall level of environmental protection in the Nin–Prevlaka–Vrsi agglomeration. With cleaner groundwater, reduced pollution, and improved coastal water quality, the region is better positioned to preserve its natural resources over the long term.

As a result, the project has also supported sustainable regional development, helping the Nin–Prevlaka–Vrsi area further establish itself as a growing and attractive tourism destination. By combining improved infrastructure with a higher environmental standard, the project lays the foundation for continued economic growth and long-term resilience.
