The completed engineering structure intended to preserve biological resources is currently at the commissioning stage. After the fish protection structures are commissioned in a pilot mode, their performance will be monitored over the course of the year. In October 2021, they are supposed to be put in commercial operation.
To ensure the performance indicators prescribed by regulatory documents, the design engineering solutions were selected with due regard for the water bed configuration and velocity shape. The branch prepared the ichthyological and biological fish-breeding rationale for the protection structure design and position and obtained all necessary approvals and permits.
The decision to implement the project of a system of fish protection structures (Surgutskaya GRES-2 BPS water intake supply channels) was made upon completion of all statutory procedures. It is worth mentioning that Surgutskaya GRES-2 uses water resources in accordance with the water use contracts made in compliance with the requirements of the Water Code of the Russian Federation. The water is taken in to supply the main and auxiliary equipment cooling systems with process water, make up for steam-and-water losses, and supply the power units from the Surgut reservoir that is a process water body. On par with the phase-out of two sludge disposal bowls, fish protection structures represent yet another crucial environmental project implemented by Surgutskaya GRES-2 in the region.
