Overview
Split Solin Stupe is a primary treatment plant serving the Split area in Croatia. Located near the Adriatic coast, it has a designed capacity of 150,000 cubic meters per day.
Split Solin Stupe is a wastewater treatment plant located in the Splitsko-dalmatinska županija region of Croatia, serving the greater Split metropolitan area. The plant is situated near the Adriatic coast and has a designed capacity of 150,000 cubic meters per day, indicating it serves a large agglomeration. As a primary treatment facility, Split Solin Stupe provides basic physical treatment to remove settleable solids. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), large agglomerations (over 150,000 population equivalent) in sensitive areas are typically required to have more advanced treatment. However, Croatia's implementation plans may include transitional arrangements for coastal discharges. The plant's treated effluent is discharged into the Adriatic Sea, a semi-enclosed marine environment with limited water exchange. The Adriatic Sea supports diverse marine life and is an important fishing and tourism resource. Discharge of primary-treated wastewater can contribute to nutrient loading and potential eutrophication in coastal waters.
Environmental context
The plant discharges into the Adriatic Sea, a narrow arm of the Mediterranean Sea bordered by Croatia's Dalmatian coast. This marine environment supports diverse ecosystems including seagrass meadows and coral habitats, and is an important migratory corridor for marine species. Nutrient inputs from primary-treated wastewater can contribute to local eutrophication, particularly in semi-enclosed bays near Split.
Frequently asked questions
Split Solin Stupe is located in the Splitsko-dalmatinska županija region of Croatia, near the city of Split on the Adriatic coast.
The plant has a designed capacity of 150,000 cubic meters per day, making it a large-scale facility serving the Split metropolitan area.
The plant provides primary treatment and discharges treated effluent into the Adriatic Sea, a coastal marine environment.
As a Croatian plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for collection and treatment based on agglomeration size and receiving water sensitivity.
For large agglomerations over 150,000 population equivalent discharging to coastal waters, the EU directive requires at least secondary treatment, though transitional periods may apply. Primary treatment is less common for this scale.
