The works on the modernisation and upgrade of Vonarje Dam on the Croatian side of Sutlansko Lake officially began on Tuesday, 14 May 2019. The works are financed through the FRISCO 2.1 Project –Cross-Border Harmonized Flood Risk Reduction 2.1 – Structural Measure Vonarje Dam under the Cross-Border Cooperation Programme INTERREG V-A Slovenia-Croatia.

This investment is implemented jointly by Hrvatske vode and the Slovenian Water Agency under the FRISCO 2.1 Project through two works contracts in the total value of EUR 2.1 million or HRK 15.5 million, of which EUR 1.36 million or HRK 10.1 million is provided from the above-mentioned EU programme.

The contractor on the Croatian side is a consortium of Croatian companies consisting of Niskogradnja Hren d.o.o. from Donja Stubica, GEOKON-ZAGREB d.d., Hamowa-Hidro TPK d.o.o. from Karlovac and Elektrowat d.o.o. from Zaprešić.

Mr Zoran Đuroković, the General Manager of Hrvatske vode, pointed out that the value of works on the Croatian side of the dam amounted to HRK 10.7 million, of which EUR 1 million comes directly from EU funds, which significantly facilitates the investment.

“The construction of the dam will first of all bring better flood safety to this region since it will store a large volume of the Sutla river waters which will thus pose a lower risk downstream. With the improvement of the lake, it will also contribute to the future needs of tourism and recreation in this region”, said Mr Đuroković, adding that the works on the reconstruction of part of the dam would be completed by the end of November, after which the regulation of the lake itself would start, in coordination with the Slovenian side.

The works include the reconstruction of the dam’s structural elements, replacement of worn-out hydro-mechanical and operating equipment, replacement and upgrade of electrical installations and equipment, and installation of equipment for automatic operation, remote control and monitoring of dam operation and condition.
