Water Intake System of the Hydro Power Plant

Posted on October 16, 2012 by team

We have already written about the Chiryurtskaya hydropower plant (1, 2).

Now you are about to see how its water intake is arranged and how Gelbakhskaya hydro power plant is concerned.

But let’s refer to some history first. In the central mountains of Dagestan, at the confluence of the Avar and Andi Koisu forms a rapid river Sulak. This is one of the largest river systems of Dagestan with its total length of 144 km (89,5 miles).
The complex of the Chiryurtskiye hydro power plants includes three power plants: Chiryurtskaya HPP -1, Chiryurtskaya HPP -2 and Gelbakhskaya HPP (Chiryurtskaya HPP -3).

Some photos of the construction: chutes are being built.

This is the photo of the construction of spillways and bottom earthen dam.

Pay attention to the crane lying on its side.

From here the water flows to the diversion canal.

This is the Chiryurtskoye dam. It is already old and silted with sediments.

It’s the repair gate and the trash screen of the head end.

This is the head end itself.

The diversion canal of Chiryurtskaya HPP-1 is 3458 m (2,14 miles) long, 7 m (23 ft) wide on the bottom and 8,8 m deep (29 ft).

The bottom spillway gate is open to make water flowing into the river cleaner.

This is the Sulak river.

At the head end the water intake for the diversion canal and the bottom discharge (in front) are connected.

    These pictures are beautiful and the color of the water is very interesting. I wonder if some people that live near can have electricity for free,or maybe some discount? This is why in Canada we don’t say electric bill we always say the hydro bill.

    Hohohoooo! The truck in the picture #4 is the 50s Czechoslovak Skoda 706 RTD – vehicle absolutely unappropriate for off-road riding. Its most common role was in brewery deliveries, as its bed takes an enormous amount of beer crates …

    Nowadays its status is a “vintage”, see:

      My guess, is that Soviet trucks broke down so often, that even Czechoslovak beer delivery trucks were better suited for the job… any job, that is.
