What are the water supply and drainage systems?
Water Intake and Supply Infrastructure
The Konakovo Power Station relies on a uniflow technical water supply system sourced directly from the Volga River, specifically drawing from the Ivankovo Reservoir located adjacent to the plant site in Tver Oblast. This hydraulic arrangement is critical for the thermal power generation process, providing the necessary cooling capacity for the station's operational units. The intake infrastructure is designed to handle the volumetric flow requirements of the 2520 MW facility, ensuring consistent water availability for condensers and auxiliary systems throughout the annual cycle of the reservoir.
The water conveyance system includes a dedicated channel with a length of 2.4 km, which transports the raw water from the river intake to the plant's processing and cooling structures. This channel is engineered to maintain hydraulic efficiency and minimize head loss during the transfer phase. The system utilizes specific pumping equipment, identified by the model designation ОП-5ПВ, to regulate the flow rate and pressure required for the station's internal distribution networks. These pumps are integral to maintaining the thermal balance of the power generation units, particularly during peak load periods when the demand for cooling water increases significantly.
Wastewater Management and Drainage
After passing through the thermal exchange processes within the power station, the used water is managed through a structured drainage and treatment protocol. The wastewater output from the Konakovo Power Station is integrated into the broader municipal infrastructure, utilizing the city of Konakovo's treatment plants for final processing before discharge. This integration allows for a more efficient use of local resources and ensures that the effluent meets the environmental standards required for the Volga River ecosystem.
The drainage system is designed to handle both the primary cooling water discharge and secondary wastewater streams generated by the plant's auxiliary operations. By leveraging the city's treatment facilities, the station benefits from centralized processing capabilities, which can adapt to variations in water quality and volume. This approach supports the operational continuity of the plant, which has been in service since its commissioning in 1965, and aligns with the environmental management practices of the operator, EL5-Energo, a subsidiary of Enel Russia. The uniflow nature of the supply system means that the water is not recirculated within a closed loop for the primary intake, but rather drawn, used, and then discharged through the municipal treatment network, creating a continuous hydraulic cycle between the reservoir, the plant, and the city infrastructure.
