THE VASO RE (THE RE’ DUCT) SYSTEM WITH THE DRAIN INTO THE GRIGNA

This is a strategic position for understanding the structure of the Vaso R (the R Duct) system, just where takes place the regulation of the flow and its subsequent drain into the Grigna stream.
It is still significant for this the vision of the complex plumbing work with the structure of the “gardna|l”, in other words of the section of the wall built up to divert the water from the main pipe, of the “srott” for blocking the water with the well preserved flywheel and a small bridge that consents the connection with the farmyards that are situated below Via Ripa (Ripa’s Street).
Exactly from above, where you find the flywheel and the connection to the farmyards, you can see the Vaso R (the R Duct) structure entirely in masonry and perfectly preserved, but the level of the ground, where the artificial flume flows, is significantly lower than the country of Bienno. This brings us back to the tragic landslide with the consequent flood that in 1634 dragged off the southern part of the territory of Bienno.
For this reason in this area the Vaso R (the R Duct) flows among the meadows and there are not other forges besides the “Parada”, which probably was saved from the disaster.
Just the cultivated areas next to the Vaso R (the R Duct) used the water of the duct, generally at night when water was not used for the factories, the irrigation through the “dgai”, pipes digged in the ground, which were also used in areas at the side of the Grigna stream, where water was directly gathered.
The great flood happened in 1634 changed radically the urban structure of the different countries of the Grigna Valley; and it is still visible especially in Prestine, where the high walls on which the inhabited place is expanded, witness the occurred wash that demolished half a country, but also in Bienno exactly the presence of the high arched wall that supported Via Ripa (Ripa’s Street) and the strong subsidence that divides the two sides of the Grigna stream, take back to that tragic event.
The Vaso R (the R Duct) can be followed for a long stretch among the farmyards, which for their position that is particularly favourable, are famous for the production of excellent fruit and vegetables.
After the ruin occurred in 1634, the people of Bienno did not build any more forges and houses in this area, as if they did not want to forget that the water, despite the fact that it is a valuable good, can become much more terrible than the fire: “al fac burga a l’iva fzga” - the fire can be extinguished, but when the water is rushing, you had better escape [Municipal Library of Bienno, edited by Morandini Giacomo, Proverbs, idioms, jokes and songs of the Folklore of Bienno, 1978].
