KMG recognizes its responsibility to society and the environment and is making every effort to ensure the efficient use of water resources. In 2018 at an HSE forum for CEOs of KMG Group companies, we signed a Statement of Commitment to efficient water management (Eight water-related principles). The Standard sets out Company’s key water use principles, systematizes the approach to their management by KMG’s subsidiaries and associated companies, and helps increase the commitment of the Company’s managers and employees to saving fresh water.
Projects are being implemented aimed at reducing discharges and reducing water intake from natural sources. In 2020, the CDP reports have been expanded and in 2021 for the second time the water management data was published on the CDP website as part of the Water Security Questionnaire 2020. For more information, refer to the published KMG reports available at: CDP Water Security Questionnaire.
The total water intake of the KMG Group in 2021 was 84.34 million m3 including surface sources - 36.85 million m3, underground sources - 25.99 million m3, urban water supply systems - 3.30 million m3, sea - 18.11 million m3, wastewater from other enterprises - 0.08 million m3.
The specific coefficient of water consumption in the «Oil production» line in 2020 was 2.19 m3 of water per 1 thousand tons of oil produced; The specific water consumption coefficient in the «Oil Refining» line in 2020 was 0.85 m3 of water per 1 thousand tons of processed oil.
In 2021, the KMG Group discharged 13,59 mln m3 of wastewater. After wastewater treatment in treatment facilities, the water treated to standard quality is discharged to specialized facilities: collection ponds, evaporation fields, and filtration fields. The enterprises that have no own storage facilities transfer wastewater to specialized companies for treatment and discharge under the signed contracts. After treatment, wastewater is reused for vehicle washing, dust suppression, and fire-fighting systems. At this, a significant volume of the treated wastewater is recycled at the refineries only where in 2021 3.97 mln m3 of treated wastewater was recycled. Such water is mostly used for makeup of circulating water supply units. The percentage of water recycling at the KMG plants was 24 % (from the total water intake in the Oil Refining area). In total, the recycling water systems of the KMG refineries used (recirculated) 389.99 mln m3 of water. Oil production generates large volumes of so-called produced associated water: water-oil emulsion is drawn to the surface, which is then separated into water and oil by gravity. After settling in this manner, water is injected to the reservoir.
