Water Management

The Company operates in accordance with sustainable water use and conservation principles and the requirements of Russian environmental legislation. Gazprom Neft implements a set of measures aimed at reducing environmental risks in this area and improving the environmental condition of water bodies and coastal areas.

The Company upgrades water treatment plants, maintains and repairs wells, and performs laboratory and instrumental monitoring of water protection zones, surface waters, groundwater, and wastewater. It also evaluates the condition of surface water bed silt deposits. Production facilities conduct non-destructive testing and pipeline monitoring at water crossings and arrange for underwater surveys of the areas in order to enhance the reliability of water crossings.

The increase in the volume of water in water reuse systems is the result of increased oil production. The increase in the volume of water in water recycling systems is the result of an increase in oil refining volume. In this regard, the Company continues to work on increasing the volume of used water in water recycling and reuse systems. At the Omsk and Moscow refineries, projects to create enclosed treatment facilities have been launched. The new facilities make it possible to remove up to 99% of pollutants from the water. Up to 70% of the water can be returned to the production cycle, reducing the burden on municipal treatment facilities. The design of the treatment facilities at Omsk Refinery involves the creation of an aeration tank (a tank in which bacteria consume the residual hydrocarbons) and sedimentation tank. The Moscow Refinery will use a purification technology based on a membrane bioreactor.

The Company mainly disposes of wastewater at filling stations. The network of filling stations is designed and constructed in accordance with the requirements and standards of environmental protection regulations. Filling stations have storm, industrial, and commercial water treatment facilities. The volume of wastewater increased in 2014 due to an increase in the number of filling stations.
