The works on the wastewater treatment plant should be completed within 26 months, the municipal government said on Wednesday.
Germany's state-owned investment and development bank KfW provided a grant of 13 million euro and the Swiss State Secretariat for Economic Affairs (SECO) granted over 4 million euro for the realisation of the project. The remaining funds were secured by the City of Zenica, the municipal government said.
