Construction of a Wastewater Treatment Plant in Poland

KGHM Zelazny

Measures

To ensure compliance with rigorous international environmental standards, KGHM has an ongoing program in place to monitor air, soil, plants, surface and underground water contamination levels, as well as the wellbeing of livestock, around all of its mining and metallurgical operations. Continuous monitoring helps in making rational and diligent decisions related to sustainable waste management.

In 2017, KGHM received environmental approval for the construction of an extension to the Żelazny Most Tailings Storage Facility, which is the only place where ore flotation residues from all of KGHM’s mines can be deposited. Excess water in the Żelazny Most reservoir is discharged periodically using the hydrotechnical method, a process developed and implemented in cooperation with scientific entities and in accordance with the requirements of the Water Law Act. Following the extension of the existing facility to 195m above sea level, it will be able to deposit as much as 950 million m3 of waste to 2038 (up from the current 657 million m3).

Benefit

The Żelazny Most Tailings Storage Facility is one of the best-monitored facilities of this type in the world, using a geodetic observation network with as many as 500 sample points. Research shows the discharge of mine and technological waters to the Odra River cause absolutely no changes that could affect the proper functioning of aquatic ecosystems.
