Wastewater discharge

The environmental aspects of the formation and discharge of effluent into surface waters and central wastewater disposal networks are constantly monitored by the respective LUKOIL department and by specialists within its subsidiaries. Key measures to minimize the negative impacts of effluents on the quality of water bodies comprise:

• ensuring in-process monitoring of the quality of effluents
• commissioning new and/or renovating existing treatment facilities
• performing diagnostics and overhauls of pipeline transport
• building systems that initially separate and utilize formation water
• treating contaminated groundwater from drainage systems

We were able to put a complete halt to the discharge of undertreated effluent into water bodies at oil refining, petrochemicals, and electric power engineering subsidiaries.

In 2017 the main measures to deal with this issue at oil and gas production subsidiaries included building effluent treatment facilities at Yareganeft and LUKOIL-Komi (the facilities are scheduled for commissioning in 2018).

The ESP for 2018-2020 includes measures to design or upgrade biological treatment facilities at oil refining and petrochemical subsidiaries in order to maintain discharge treatment quality.

In 2017 the share of undertreated discharge in total wastewater disposed by LUKOIL Group subsidiaries continued to be insignificant (0.5%).
