Fish kill in Sava River raises alarm; Holding denies plant malfunction

Concerns have been raised following the discovery of a significant number of dead fish in the Sava River near Zagreb.

The association "Ekologija grada" (Ecology of the City) initially claimed that untreated wastewater had been discharged from the Central Wastewater Treatment Plant (CUPOV Zagreb), presenting photographs of the dead fish. They urged relevant institutions to investigate the incident, conduct analyses, and publicly share the results.

However, Zagrebački Holding, the entity responsible for the plant, has denied any extraordinary events or malfunctions. They stated that the purification processes have been continuous and unimpeded, with the system remaining stable and functional. According to Holding, both regular and extraordinary checks have confirmed no operational issues in recent days.

Zagrebački Holding emphasized that all output parameters for the treated wastewater comply with legal regulations. They explicitly refuted the claims of an "extraordinary event" at the plant. Regarding the fish kill and the state of the Sava River, Holding clarified that the "Vodoopskrba i odvodnja" company is not responsible for monitoring the river's water quality indicators or determining the impact of drought and climate conditions. These responsibilities, they noted, fall under Hrvatske vode (Croatian Waters).
