Overview
Makarska Sv Petar is a primary treatment plant serving the coastal city of Makarska, Croatia. With a designed capacity of 50,100 m³/day, it discharges treated wastewater into the Adriatic Sea.
Makarska Sv Petar is a wastewater treatment plant located on the Dalmatian coast in the city of Makarska, Croatia. The facility serves the local population and tourist influx, with a designed capacity of 50,100 cubic meters per day, placing it among medium-to-large agglomerations in the region. The plant provides primary treatment, which involves physical sedimentation and screening to remove solids. As a coastal facility within 10 km of the Adriatic Sea, it operates under Croatia's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). This directive requires at least secondary treatment for discharges into sensitive coastal areas, though primary treatment may be permitted with appropriate marine outfall dispersion. Treated effluent from Makarska Sv Petar is discharged into the Adriatic Sea, a semi-enclosed sea with limited water exchange. The coastal waters support diverse marine life, including seagrass meadows and fish spawning grounds. Proper treatment is essential to prevent eutrophication and protect bathing water quality along the popular Makarska Riviera.
Environmental context
The plant discharges into the Adriatic Sea, a narrow arm of the Mediterranean Sea bordered by Croatia's Dalmatian coast. This coastal zone supports ecologically sensitive habitats, including Posidonia oceanica seagrass meadows and coralligenous reefs, which are vulnerable to nutrient enrichment and pollution. The area is also a major tourist destination, making water quality critical for both ecosystem health and recreational use.

As a Croatian plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for discharges into coastal waters to protect the marine environment.
Coastal plants in Croatia often provide at least secondary treatment to meet EU standards, though primary treatment with long outfalls may be accepted in some cases. The directive mandates secondary treatment for agglomerations over 10,000 population equivalent discharging into sensitive areas.
