In early November 2026, Bihać City Council approved a decision to register the wastewater treatment plant in Velhovo, worth 18.5 million KM, in the City’s books. The decision is a precondition for repairing the plant, which protects the Una from the town’s untreated wastewater.
What was decided
According to reports by Klix.ba and BosnaInfo, the plant had not previously been recorded in the City’s books. With the decision adopted, it becomes the property of the City of Bihać, and its management is entrusted to the public utility Vodovod Bihać. Construction was financed from several sources, including a grant from the German development bank KfW, the Environmental Protection Fund of the FBiH, the Government of the FBiH and the City of Bihać. The plant opened on 5 July 2017.
Why this matters for the Una
The city administration recorded ground subsidence at the Velhovo site in 2023 and 2024, and repair and reconstruction have been estimated at around 16.5 million KM. In October, Mayor Elvedin Sedić warned that without a solution, wastewater from more than 11,000 households could end up in the Una. The proposal to register the plant had previously been rejected and was adopted after a change of majority in the City Council.
Nothing changes for visitors right away: walks along the Una and trips to Una National Park continue as before. The decision is still important for the long-term cleanliness of the river that brings most visitors to Bihać. Find more about the river and the area in our Bihać travel guides.
