Water engineering

Considering the limited resources and development sustainable in the long term, it is our duty to protect and conserve water resources for all generations. At Institut IGH we keep pace with the market needs, and since the water engineering sector is nowadays attracting both global interest and investment focus, we offer all services required for the development and implementation of sustainable water management projects, as well as for water engineering projects in general.

01Water engineering structures

As a part of water engineering systems for protection against harmful effects of water, water use and protection, there are different types of water engineering structures such as embankments, canals, locks, pumping stations, pipelines, treatment plants etc. Institut IGH participates in design development and implementation of projects of water engineering systems and structures in all phases, including study documentation and conceptual designs, investigations and design documentation, tender documents and technical supervision.

Among recent projects we are taking part in, projects of protection against harmful effects of waters that will be funded from EU Structural Funds through the Operational Programme Competitiveness and Cohesion 2014-2020 (OPCC) deserve special mention, such as the EU Project Modernization of Embankments on the Left Bank of Sava River from Račinovci to Nova Gradiška (of total length over 200 km), the first project of construction measures for flood risk management was approved for co-financing through OPCC, on which Institut IGH participated in preparation of study and design documentation or the Flood Defence Project for the Town of Ogulin, which is centred around the key water engineering structure Ogulin Detention Basin, for which Institut IGH prepared design documentation.

02Irrigation

Since 2005, the Republic of Croatia has been systematically implementing the National Project of Irrigation and Management of Agricultural Land and Water in the Republic of Croatia (NAPNAV Programme), with the objectives of introducing measures of systematic infrastructure organization in agriculture, land consolidation and introduction of new production and irrigation technologies (on 65,000 ha), which will ensure a more efficient agricultural production and stimulate regional rural development.

Our activities so far included development of design documentation for numerous irrigation systems. Intensive construction is planned to be co-financed from EU Funds through Rural Development Programme 2014-2020 and the future national and international co-financed programmes.
Institut IGH has been participating in implementation of the Planning and Design Programme since 2006 and it has so far participated in preparation of a large number of irrigation projects, which when added up cover the largest total area of all design companies in the Republic of Croatia. In these irrigation plans and projects, Institut IGH comes up with and elaborates the best water management and technological solutions, which maximize project benefits in compliance with the objectives of the Programme.
We prepared the irrigation plans for Koprivnica-Križevci County, Sisak-Moslavina County, Bjelovar-Bilogora County and Karlovac County, feasibility studies for numerous significant irrigation projects, such as the Biđ-Bosut Field Irrigation Project and preliminary, detailed and/or working designs for numerous significant irrigation systems, such as the Baranja Irrigation System Project, which extends over 5,000 ha.

03Use and protection of water

Institut IGH participates in development of EU projects for water supply and drainage systems by preparing the study and design documentation at all levels of development. In these projects, Institut IGH finds and elaborates the best water management and technological solutions, which maximize project benefits.

During pre-accession negotiations with the EU, the Republic of Croatia assumed significant obligations related to the implementation of the Water Framework Directive and other relevant EU Directives that refer to water supply, drainage and wastewater treatment. Accordingly, the preparation of study and design documentation was commenced, as well as intensive implementation of numerous projects of regional water supply systems, and wastewater drainage and treatment system of agglomerations, which are co-financed from the EU structural funds.
Institut IGH took part and is taking part in preparation of feasibility studies for numerous agglomerations, including Zagreb, Virovitica, Križevci, Donji Miholjac and Pitomača, as well as preparation of design documentation for numerous agglomerations, of Zagreb, Cres-Lošinj, Novi Vinodolski, Split-Solin, Plitvice Lakes, Preko and Kali, Otočac, Opatijska Riviera, Ivanić Grad. Moreover, we prepared design documentation for many water supply and drainage systems financed with national funds.

04Canals and navigable waterways

Institut IGH is involved in the development of study and design documentation for inland waterways and ports, as well as for man-made canals with other water management uses. In these projects, Institut IGH finds and elaborates the best water management and technological solutions, which maximize project benefits.

Since inland navigation often represents the optimal mode of transport, in compliance with the Transport Strategy of the Republic of Croatia, the development of inland navigation is stimulated through upgrade of inland waterways and ports in the Republic of Croatia, including international navigable waterways, by preparing and implementing projects that will be co-financed from EU structural funds.
As the Lead Partner of the Consortium, Institut IGH participated in the last amendments and revisions of study and design documentation for the Multi-purpose Danube-Sava Canal (MDSC), by which owing to the construction of the navigable channel from Vukovar to Šamac in the length of 63 km, the waterway from Croatian ports on the Sava River to the international corridor between the North and Black Sea will be shortened by 400 km, while enabling other important water management (irrigation, drainage) and ecological benefits.
Also, we participated in development of design documentation for recently executed projects of artificial channels in the Republic of Croatia – 13 km long irrigation channel from Sava to Konjsko Channel with pumping station on the Sava River (first phase of the MDSC) and 12 km long drainage Lateral Channel Kneževi Vinogradi-Zmajevac, which serves for irrigation and drainage in Baranja.

05Hydro power systems

IGH participates in the development of study and design documentation for water engineering systems and multi-purpose systems that have a hydropower component at all levels. In these projects, we come up with and elaborate the best water management, hydropower and technological solutions to maximize the project benefits.
In addition to preparing study and design documentation, IGH also participates in producing the best hydraulic solutions by performing investigations on physical models at the Water Engineering Laboratory of IGH.

Even though a greater part of hydro power potential of the Republic of Croatia has already been exploited, significant multi-purpose projects are being planned and prepared, which will harness the remaining hydro power potential in the Republic of Croatia up to the limits of economic viability, including achieving of other socio-economic benefits.
As a Lead Partner of the Consortium, Institut IGH participated in the development of the working design for the last hydropower facility constructed in the Republic of Croatia, which is HPP Lešće on the Dobra River, completed in 2010. Furthermore, we participated in the development of the concept and conceptual design for the multi-purpose Programme of Protection, Regulation and Use of the Sava River from the border with the Republic of Slovenia to Sisak (“Sava Programme” or “Zagreb on Sava”), especially in the part that refers to an increase in capacity of the bypass channel Sava-Odra, which would enable the execution of hydropower facilities and urban development along the banks of the Sava River in Zagreb.
In terms of hydraulic design optimization, we perform complex investigations on physical models for outlet works of the possible HE Ombla near Dubrovnik, which would be unique in the world for its underground storage reservoir formed by a grout curtain, 100 m in height.
