Basic characteristics of the construction and its operation in the future:

Water work Trenčianske Biskupice 2 was designed in order to produce electricity by utilization of hydro-energetic potential of three boulder stages below the existing weir in Trenčianske Biskupice. The maximum usable flow of the hydro power was fed through a decontamination flow below the weir, while taking into account an excess flow curve in a given profile. Maximum usable flow was determined at 20.00 m3.s-1.

The water work axis was designed approximately 530 m below the axis of the existing weir, right above the water spillway from the right-bank sewage plant of the city Trenčín. The upper water level was designed in order not to swell the lower level of SHPP Trenčianske Biskupice, situated below the right-bank mounting of the weir. The lower water level was designed in consideration of the water level in the lower lagoon, taking into account estimated erosion processes of the Váh riverbed. The solution of downstream riverbed was adjusted accordingly.

The basic technical concept was based on the solution of river stage situated right in the river bed of the stream, consisting of a three-field weir construction, a building of the small hydro power plant, which was fixed on the left-side bench. A bristled fish pass was established between the body of the weir and the hydro power building. It is made of three arms. A power outlet is designed into the existing 22-kV line, running along the left-bank protection dike. Safety of the water work was designed equally to the protected left-bank area of the town Trenčín.
