When the river runs with the increased load, maintained its high level, which is regulated by heavy rainfall discharge of the water in the regulating reservoir through the fill, eliminating flooding of adjacent areas. In addition, maintaining a high level of the river and the preservation of the river lead to the increase in the number of fish and increase fish spawning, while improving the ecology of the river due to sediment water regulating reservoirs.

The basic capacity of the main reservoir located below the regulatory reservoirs and on the plot with a large difference of level of the river with channel filling, connected with the river and the dam height to the top is about level, performed respectively in the upper and lower level areas, and placing pressure conduit below the level of the main reservoir and is made in the form of pressure pipelines with length not less than 12-15 km depending on the difference of level of the river for a given pressure coming from the main reservoir, namely in the form of winter discharge pipe for the minimum consumption of water and n number of penstocks for summer maximum flow connected to the conduit of the turbine, as well as the supply of hydroelectric power compensation reservoir, situated at the level of the pressure conduit turbines connected to the conduit of the turbine and provided with a pump unit, allows to keep a constant pressure and to adjust the load on the turbine by means of the pumping station associated with compensation reservoir, increasing efficiency, because at the lowest load consumption in the network part of the volume of water pumped to the compensation reservoir and can be used when the load increases consumption.

In addition, the length of the pressure pipe reduces the amount of flood-prone areas, keeping the river, improving the ecology of the river.
