The feasibility study covers the region of the City of Bjelovar and the Municipality of Rovišće. A solution for wastewater drainage and purification was proposed for the entire respective area, alongside a water supply solution. In Phase 1, covered by the application, the project documentation was drafted, and the location and construction permits were obtained. Phase 1 included the reconstruction of the existing wastewater drainage system for the City of Bjelovar over the length of 2,595 meters, extending the existing wastewater drainage system for the City of Bjelovar over the length of 15,790 meters, extending the wastewater purification device for the Bjelovar agglomeration 47.000 ES, reconstructing the existing water supply system in the City of Bjelovar covering the length of 6,204 meters, constructing 14,281 meters of water supply pipelines in the area of Rovišće Municipality and procuring the equipment for the maintenance of the water supply system as well as wastewater drainage and purification systems.
In January 2019, construction and technical inspection of the first section from the modernization of the Sava river dikes project – at the Klakar-Ruščića section covering the length of 5100 meters – was completed. The completion of this section was the final part between the western lateral channel of Biđ-Bosutsko polje and the Glogovice channel which provides protection for 2911 inhabitants against the harmful effects of water.
Preparation of the survey map for the EU project Modernisation of the Sava river dikes from Račinovci to Nova Gradiška – Services involving geodetic and aerial photogrammetric measurements
The largest infrastructural linear project surveyed using an unmanned aerial vehicle in the world carried out in Croatia
The area along the left foreshore of Sava River from Račinovci (rkm 212.080) to the Trnava confluence at Nova Gradiška (rkm 464.500) is protected against floods by a continual line of river dikes covering the total length of 236 km.
Upon drafting the project, a georeferencing video of the Sava River was created covering the respective section and a geoid model for the project area.
The call for drafting bids for the project “Undertaking of Preparatory works, Drafting of the Main Design and Tender Documentation for Construction Permits for Renewal of the Waterway on the Sava River up to Class Va from Belgrade to Brčko (rkm0.0-rkm234.0)” was published and issued by the Ministry of Transport and Communication of the Republic of Bosnia and Herzegovina on 24 May 2012. The company Vodoprivredno-projektni biro d.d. from Zagreb in a consortium with the company IGH d.d. also from Zagreb was selected as the most favourable bidder and based on the mentioned bid, the contract was signed on 20 September 2013 between the mentioned parties.
