Reuse of treated wastewater

In order to reduce fresh water intake for such works and operations like drilling, drilling muds preparation, watering of planted trees, dust suppression on roads and constructed sites, KPO uses treated domestic, production storm wastewater and storm runoffs. The wastewater is reused at the Company facilities in line with the 2018-2022 Operating Procedure.

In 2021, treated waste water, rain and melt water, as well as groundwater from wells were also used for the technical needs of production facilities. In 2020, the volume of wastewater reused for technical needs by KPO amounted to 11.3% of the technical water consumed from the Konchubai Gully. The Company reused 35,061 m3 of treated wastewater for technical needs, mostly for dust suppression. Table below shows the activities that utilize treated wastewater and water.
