Water resource protection projects
Since 2011, EVRAZ ZSMK has been implementing a programme to protect water resources that aims to gradually close the water cycle and minimise discharge volumes. In 2017, the programme helped to reduce the freshwater intake by 4.4 million cubic metres and the discharge into rivers by 3.4 million cubic metres of water per year.
Since 2011, Raspadskaya has been implementing a programme to protect water resources by upgrading the equipment used to filter the water that it pumps out of mines and quarries. In 2017, the Raspadskaya-Koksovaya mine launched a water filtration unit that uses pressure-flotation technology with post-treatment of wastewater in a high-speed filtration and disinfection system. The Group has previously used this technology at the Uskovskaya and Erunakovskaya-8 mines. Some of the filtered water is re-used in the production cycle and the rest is discharged into rivers in compliance with all environmental standards.
