Water Resources Protection

Every year, the Gazprom Group takes steps to reconstruct and modernize water supply and wastewater systems at Gazprom facilities, aiming to increase the efficiency of water use for industrial and utility purposes. To improve wastewater treatment quality and reduce hydrocarbon pollution, Gazprom is developing and implementing new technologies, including a treatment method based on granular aerobic activated sludge combined with the Collector and Biosorb agents. This approach significantly accelerates the elimination of hydrocarbon contaminants and reduces the negative impact on the environment.

Gazprom Group entities regularly measure and monitor the total volume of wastewater at all of their production and administrative facilities and analyze their impact on ecosystems. As required by the applicable laws, Gazprom Group entities measure and monitor wastewater quality (including temperatures) to make sure it meets the regulatory requirements.

The Gazprom Group actively engages with stakeholders in relation to water resources and does its utmost to guarantee high water quality in the regions of operation. The Gazprom Group's significant projects are subject to public hearings before being submitted for state expert review. The Gazprom Group analyzes stakeholder expectations related to water resources and does whatever is necessary to meet them. The interests of stakeholders are also taken into account when disclosing information on water use.

As a water supplier in certain Russian regions, Gazprom is responsible for providing the local communities and other water users with clean water. In a number of cases, Gazprom receives wastewater under contracts with external parties, making it responsible for wastewater discharges unrelated to its own production operations.

The Gazprom Group ensures timely acquisition of water use permits and adheres to all related requirements. The Group maintains accurate water use records and reports and complies with sanitary and hygienic standards at all of its production facilities.

Water is withdrawn from surface and subterranean sources solely in accordance with the effective legislation and pursuant to water use agreements and licenses, without causing any significant impact on the environment. Gazprom does not operate in areas with water stress.

The company responsible for most of the water consumption and, accordingly, water discharge into surface water bodies is Gazprom Energoholding, as its hydro power plants generate energy using a once-through cooling system.

The Gazprom Group's water consumption increase in 2023 is related to higher power generation by Gazprom EnergoholdingElectricity production at GRES and thermal power plants involves the use of process water in cooling systems for steam condensation, as well as for cooling and cleaning equipment. An increase in electricity generation inevitably leads to higher water consumption and an increase in the volume of water discharged..

Discharges into surface water bodies account for 98.3% of the Gazprom Group’s total wastewater discharge volume.

The increase in the volume of recycled water in 2023 was due to higher power generation by Ryazanskaya GRES (OGK-2, Gazprom Energoholding). The volume of reused water was down in the reporting year as a result of Mosenergo’s reduced reliance on reserve fuel (fuel oil) and therefore less volumesof generation of oil- and fuel oil-contaminated  water sent for treatment and then sent to reuse as source of additional supply for heating grids or the equipment circulating cooling system.
