The conceptional focus of the water-plant construction is based on the idea that the
installation should functionally be recognized as a machine with all
operations visible to everyone. The different buildings are connected
with a band – the base. Aboveground they are only covered by an all
weather shell. The water-plant is in the focus of the observer –
all other structural works are reduced in appearance.
The installation is to be
experienced in its technique and its operating sequence. In the
design, process parameters, such as capacity, height and hydraulic
thrust, were the most significant.
The localisation of the
water plant is defined by the last water catchment in Küblis, the
position of the landquart and the smallest distance between surge
chamber and the power house at the foot of the mountain.
The alignment of the plant
is the result of the minimization of sources of error. The
construction is parallel to the aboveground waterpipe. The
straight-lined run of the pipe between plant and power house helps
avoid irregularities in the aquifer system.
The shape of the power
house is defined by the travelling bridge, needed to change the
turbines. Its appearance is optimized in form - triangular instead of
the common rectangular frame. The power of 10 kN/m² at a height of
fall of 245 m is confronted with a massive building at its end. The
powerhouse itself is clearly defined by its starting point – the
water input, and its end – a massive bumper.
The installation becomes
an object of attention, an electro-optical sensation: the flow of
water can be tracked from the surge chamber to the power input in the
grid.
The visitor can observe
all this by walking around and through the plant. He can observe
where the water comes from, how it is lead, used and transformed.
