A 29-meter high water tower in Haganj has been ceremoniously erected in the Vrbovec area. 

This is the fifth and final tower of the Haganj project, valued at 646.8 thousand euros, and was constructed as part of the EU project "Regional Water Supply System of Zagreb County – East Zagreb" worth over 93 million euros.

The ceremony was attended by Zoran Đuroković, the General Director of Croatian Waters (Hrvatske vode), Tomislav Masten, the Director of Water Supply and Drainage of Zagreb County (Vodoopskrba i odvodnja Zagrebačke županije d.o.o.), and Ljubica Ambrušec, the Mayor of Gradec municipality.
The project "Regional Water Supply System of Zagreb County – East Zagreb" is a public investment project involving the construction of the Kosnica water intake and the reconstruction and construction of the water supply system in the eastern part of Zagreb County. Its main purpose is to ensure high-quality drinking water for human consumption, aiming to increase the connection rate to the water supply network, reduce losses, and enhance the reliability and efficiency of the public water supply system.
Zoran Đuroković, the General Director of Croatian Waters (Hrvatske vode), emphasized that this project will provide 30,000 new residents with the opportunity to connect to the public water supply system, while an additional 70,000 residents will experience improved water supply conditions. "We have constructed and reconstructed 425 km of the system, surpassing many other projects in Croatia. The reliability of water supply and the safety of water for consumption are no longer in question. The connection rate in this area was previously at 63%, and it will now rise to over 91%. Network losses will decrease from 30% to about 20%, enabling more efficient water supply and continuous security in the area, as well as the connection of new users."
Continuous investments are essential for the seamless functioning of the water supply system and as the foundation for further development. Currently, projects worth over 250 million euros are underway in Zagreb County, with 135 million euros coming from European Union funds. The security of this region is guaranteed for the future period.
The investor of the project is Water Supply and Drainage of Zagreb County Ltd. (Vodoopskrba i odvodnja Zagrebačke županije d.o.o.), with a total value of 93,849,394.00 euros excluding VAT. The project is financed through the Operational Program Competitiveness and Cohesion 2014-2020, with non-refundable EU funds amounting to 64,231,714.00 euros. Co-financing of the national component involves funds from the Investor, Croatian Waters (Hrvatske vode), and the State Budget.
The RWS project enables long-term development of water supply in the region. The capacity of the constructed Kosnica water intake greatly exceeds current needs in the eastern part of Zagreb County, and all main pipelines have been replaced. Looking ahead to the next 50 years, there should be no issues with water supply in this area. In total, over 9,000 new free connections will be provided.
The Haganj water tower has a capacity of V = 200 m⊃3;, weighs approximately 50 tons, and stands at a total height of about 29 m from ground level. Its basic structure consists of a reservoir, supporting column, and central foundation. The contracted value for the construction works is 646,865.33 euros. The construction contract for the water supply pipelines and related facilities was signed with the consortium of Zagorje gradnja d.o.o., Aquaterm d.o.o., and Kostak d.d. Aquaterm d.o.o. carried out the construction works for the Haganj water tower.
The primary structure of the water tower includes a steel reservoir, supporting column, and reinforced concrete foundation. The reservoir and tower column are steel constructions, while the foundation is reinforced concrete. The supporting steel structure of the water tank with a capacity of V = 200 m⊃3; and total height H = 29.0 m is a steel pipe column, 21.06 m high from the top edge of the foundation to the bottom of the reservoir. The supporting column consists of two parts, with an access opening at the base for entry into the column, where ladders are installed inside. The interior of the water tower is illuminated. Two pipes are provided in the tower: one inlet-outlet pipe of diameter NO 150 and one overflow pipe of diameter NO 150. The tower will be filled from the Cugovec pumping station, which is nearing completion. It will serve to maintain pressure in the pipelines and facilitate further expansion of the water supply network.
