In order to get in a supply of water the Venetians used wells. Not existing fresh water beds they had a clever method for getting it. On the campos where you find the well parapet you will notice that at its sides there are two or four manhole covers. From these ones the rain water was canalized into a clay cistern, thus made of a waterproof material, and filled with sand which acted as a filter. Water gathered in the central pipe placed under the well and it was ready to be pulled up with a bucket. Nonetheless the water of wells could not be sufficient for all the Venetians who, thus, had to get it brought by means of scows coming from the Brenta.
