Water engineering structures
As part of hydro-technical systems for protection against harmful effects, usage and water protection, various types of hydro-technical structures appear, such as embankments, canals, dams, pumping stations, pipelines, treatment plants and other facilities. INSTITUT IGH, JSC participates in the preparation and implementation of hydraulic systems and structure projects in all phases, including study documentation and conceptual solutions, research works and project documentation, tender documentation and professional supervision.
Among the projects of hydro-technical structures in which we participated, the projects of protection against harmful effects of water that are co-financed from the EU Structural Funds through the Operational Program Competitiveness and Cohesion 2014-2020 (OPKK) stand out. Among various projects, there is the Project of modernization of the left bank of the Sava embankment from Račinovac to Nova Gradiška (total length of over 200 km). It is the first project using construction measures for flood risk management approved for co-financing through OPKK in which INSTITUT IGH, JSC, participated in the study preparation and project documentation. Another one is the Flood Protection Project of the City of Ogulin, based on the key hydraulic structure Retencija Ogulin, for which INSTITUT IGH, JSC also prepared the project documentation.
Since 2005, the Republic of Croatia has been systematically implementing the National Project for Irrigation and Management of Agricultural Land and Waters (NAPNAV Program), intending to introduce measures for systematic organization of infrastructure in agriculture, consolidation of agricultural areas and introduction of new production and irrigation technologies (65,000 ha) to ensure more efficient agricultural production and encourage regional rural development.
Through the activities so far, project documentation has been prepared for numerous irrigation systems, and intensive construction is planned to be co-financed from EU funds through the Rural Development Program 2014-2020, as well as through forthcoming national and international - co-financed programs.
The INSTITUT IGH, JSC, has been participating in the program's implementation through planning and design since 2006 and has so far participated in the preparation of many irrigation projects. Of all design companies in the Republic of Croatia, INSTITUT IGH, JSC covers the most extensive total area with these irrigation systems projects. In irrigation plans and projects, the INSTITUT IGH, JSC finds and develops optimal water-economic and technological solutions, which maximize the benefits of projects following the Program's objectives.
We have also made irrigation plans for Koprivnica-Križevci, Sisak-Moslavina, Bjelovar-Bilogora and Karlovac counties. We are also credited with feasibility studies for several significant irrigation projects, such as the Biđ-Bosut Field Irrigation Project, and preliminary, main or detailed projects of some important irrigation systems, such as the Baranja Irrigation System Project on 5,000 ha. The INSTITUT IGH, d.d. also signed a contract for expert supervision services over the project "Improvement of water utility infrastructure of the Koprivnica agglomeration" worth 11.8 million HRK, while the value of the services related to the INSTITUT IGH, JSC is slightly higher than HRK 4.9 million.
Use and protection of water
The INSTITUT IGH, JSC, participates in preparing EU water supply and sewerage projects by preparing study and project documentation at all levels. In these projects, optimal water-economic and technological solutions are found and developed, maximizing the projects' benefits.
In pre-accession negotiations with the European Union, the Republic of Croatia has undertaken significant commitments related to the implementation of the Water Framework Directive and other relevant EU directives related to water supply, drainage and wastewater treatment. Accordingly, the preparation of study and project documentation was initiated, as well as the intensive implementation of numerous projects of regional water supply systems and wastewater drainage and treatment systems of agglomerations, which are co-financed by EU Structural Funds.
The INSTITUT IGH, JSC, participated or is currently participating in the development of feasibility studies for several agglomerations, including Zagreb, Virovitica, Križevci, Donji Miholjac and Pitomača. We also prepared project documentation for numerous agglomerations, such as Zagreb, Cres - Lošinj, Novi Vinodolski, Split - Solin, Plitvice Lakes, Preko and Kali, Otočac, Opatija Riviera, and Ivanić Grad. Our experts have also prepared project documentation for many water supply and drainage systems financed from national funds.
Canals and navigable waterways
The INSTITUT IGH, JSC, participates in the preparation of study and project documentation for inland waterways, ports, artificial canals, and other water management purposes. In these projects, IGH finds and develops optimal water-economic and technological solutions, which maximize the project's benefits.
Since inland navigation is often the optimal modality of transport, following the Transport Strategy of the Republic of Croatia, its development is encouraged by improving waterways and ports in Croatia. This includes international waterways through the preparation and implementation of projects to be co-financed by EU Structural Funds.
As the leading partner of the consortium, the INSTITUT IGH, JSC, participated in the latest amendments to the study and project documentation for the Danube-Sava Multipurpose Canal (VKDS). This navigable canal from Vukovar to Šamac has a length of 63 km which would shorten the distance from Croatian ports on the Sava River to the international corridor between the North and Black Seas by 400 km. At the same time, other significant water-economic (irrigation and drainage) and ecological benefits would be provided.
Our expert team participated in the preparation of project documentation for artificial canal projects in Croatia. For instance, a 13 km long reclamation canal from the Sava to the Konjsko canal, with a pumping station on the Sava River (the first phase of the VKDS project). We would also like to point out the 12 km long drainage-supply lateral canal Kneževi Vinogradi - Zmajevac in the function of irrigation and drainage in Baranja.
Hydro power systems
INSTITUT IGH, JSC, participates in the preparation of study and project documentation for hydropower and multi-purpose systems with a hydropower component at all levels. In addition to the preparation of study and project documentation, we also participate in finding optimal hydraulic solutions through the implementation of research on physical models in the Hydrotechnical Laboratory IGH.
Although most of the hydropower potential of the Republic of Croatia has already been used, significant multi-purpose projects are planned and prepared which will use the remaining hydropower potential to the limits of economic justification while achieving other socio-economic benefits.
The INSTITUT IGH, JSC, as the leading partner of the consortium, participated in developing the detailed design for HPP Lešće on the river Dobra, which was completed in 2010. We participated in the development of the preliminary solution for the multi-purpose Program for the protection, arrangement and use of the Sava River, from the border with the Republic of Slovenia to Sisak ("Sava Program" or "Zagreb on the Sava"). This mainly refers to the increase of the capacity of the bypass canal Sava - Odra, which would enable the construction of hydropower facilities and urban development along the banks of the Sava in Zagreb.
In terms of optimization of hydraulic projects, we conducted complex research on physical models for evacuation bodies of the potential HPP Ombla near Dubrovnik, which would be unique in the world due to the underground accumulation formed by a 100 m high injection curtain.
