Work has begun on the Stupe wastewater treatment plant - a key project of the Split-Solin agglomeration

The ceremonial opening of the Stupa wastewater treatment plant marked the beginning of the implementation of one of the most significant infrastructure projects in the field of water management in the Republic of Croatia - the project "Improvement of water and utility infrastructure of the Split - Solin agglomeration".

The opening of the works was attended by the State Secretary of the Ministry of Environmental Protection and Green Transition Anja Bagarić, Director of the Directorate for Water Management and Marine Protection Elizabeta Kos, Director General of Hrvatske vode Zoran Đuroković, Deputy Director General of Hrvatske vode Valentin Dujmović, Prefect of Split-Dalmatia County Blaženko Boban, Mayor of the City of Split Tomislav Šuta and Director of Vodovod i kanalizacije d.o.o. Split Ivica Perić.

The project "Improvement of water and utility infrastructure of the Split - Solin agglomeration" is one of the largest infrastructure investments in the field of water management in the Republic of Croatia, with a total value of EUR 321,282,030.49. The total eligible costs of the second phase of the project amount to EUR 243,149,745.48, of which EUR 165,365,077.30 or 68.01% is financed by the European Union's Cohesion Fund grant. The remaining EUR 77,784,668.18 or 31.99% is provided by national sources, with Hrvatske vode contributing EUR 24,303,349.36.

The construction of the Stupe wastewater treatment plant is the most important phase of the project. The contract for the design and construction of the plant is worth EUR 99,056,751.25 including VAT. The deadline for the execution of the works is 28 months, while the total duration of the contract, including trial operation and obtaining the operating permit, is 43 months.

By upgrading the existing Stupe plant, it will become the second largest wastewater treatment plant in the Republic of Croatia, with a capacity of 275,000 population equivalents, and the central plant of a unified drainage system for Split, Solin, Klis, Podstrana and Dugopolje. For the first time, wastewater from this area will undergo a second, biological stage of treatment before being discharged into the sea, which will significantly improve the protection of the Brač Channel and the marine environment.

State Secretary of the Ministry of Environmental Protection and Green Transition Anja Bagarić emphasized that the Stupe wastewater treatment plant is the second largest wastewater treatment plant in the Republic of Croatia and another confirmation of the continuous investments of the Government of the Republic of Croatia in the development of water and utility infrastructure and environmental protection.

General Director of Hrvatske vode Zoran Đuroković emphasized that the construction of the plant will ensure biological wastewater treatment for around 275,000 equivalent inhabitants, which will significantly improve the protection of the sea, the environment and human health. He emphasized that the project includes the construction of more than 125 kilometers of sewage collectors, around 65 kilometers of water supply network, a new submarine outfall and accompanying drainage system facilities, while connecting an additional 4,027 residents to the public water supply system. He added that this is one of the largest investments of Hrvatske vode in the field of water management, which will ensure better protection of the sea and water resources in the long term.

The Prefect of the Split-Dalmatia County, Blaženko Boban, emphasized that this is a capital project that will contribute to the protection of the Brač Channel and environmental conservation in the long term and bring great benefits to the citizens of the entire county, and the Mayor of the City of Split, Tomislav Šuta, emphasized that the upgrade of the device and the introduction of a second stage of purification will significantly improve the quality of the sea and create the prerequisites for the further sustainable development of Split and the surrounding cities and municipalities.

With the completion of the project, the Split - Solin agglomeration will receive a modern and sustainable water supply and drainage system in line with European standards, with long-term preservation of sea quality, environmental protection and a higher quality of life for citizens.
