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 2020, the volume of wastewater reused for technical needs by KPO amounted to 4.8% of the technical water consumed from the Konchubai Gully. The Company reused 18,313 m3 of treated wastewater for technical needs, mostly for dust suppression. Decrease in 2020 compared to 2019 was due to reduction of the drilling scope at KOGCF and the absence of the need to make drilling mud. Table below shows the activities that utilize treated wastewater.
