Basic characteristics of the construction and its future operation:

The small hydro power plant is designed at the left spillway wing of the stilling basin in close vicinity to the weir of WW Hričov. Construction structure no. 103 the SHPP building consists of a monolithic block made of water tight reinforced concrete with a flat roof and foil sheathing. The building serves for settling mechanical and electro-technological devices, which protect against weathering factors and any possible access of unauthorized persons.

The power plant is designed with one horizontal Kaplan turbine with a runner diameter of D=1150 mm. The draft tube will lead into the stilling basin. The building has a rectangular ground design of 7.50m x 21.50m. From the point of height, the construction is divided into three underground floors and two floors above ground. On the third floor (312.450 m a.s.l.) there is an engine hall with manipulation space, a pumping aggregate, a shaft with leakage water.

In the second underground floor (316.000 m a.s.l.) there is a fixing hole leading into entrance part of the turbine and LV substation. On the first underground floor (318.450 m a.s.l.) there is a manipulation and fixing space. On the first floor above ground (±0,000=322,125 m a.s.l.) there is a main entrance with a staircase. On the second floor above ground (324.500 m a.s.l.) there is a high-voltage substation with a transformator. The building is accessible via adjusted into the first floor ±0.000=322.125 m a.s.l.
