Rational use of water resources
PJSC Rosseti’s production processes are not associated with a significant impact on water bodies. Nevertheless, the Company continuously implements measures aimed at the rational use of water resources and addresses reducing the negative impact on water bodies from wastewater discharge.
PJSC Rosseti withdraws water from both surface/underground natural water sources and centralised water supply systems. Municipal water supply systems account for about 77% of the Company’s water intake.
In 2023, water withdrawal from surface water bodies decreased by 70% in view of production needs (suspension of the transfer of the export capacity of the Vyborgskaya 400 kV substation). Total water withdrawal in 2023 also decreased by 16%, which is due to repair works at water supply facilities and the implementation of resource preservation and energy saving measures.
Wastewater is diverted and discharged from the Company’s production facilities into centralised water disposal systems and surface water bodies.
The Company monitors the quality of discharged wastewater and seeks to reduce the adverse impact on water bodies through the construction and renovation of local treatment facilities, thus cutting down the flow of pollutants into water bodies, as well as through the arrangement of sanitary protection zones for drinking and domestic water supply sources. To a limited extent, the Company utilises the recycled water supply system. In 2023, the volume of water recycled amounted to 2,000 m3.
