Ca’ Vendramin dewatering pump
NAME: Idrovora di Ca’ Vendramin (Ca’ Vendramin dewatering pump)
LOCATION: Ca’ Vendramin, Taglio di Po (Ro)
ORIGINAL CONSORTIUM OF BELONGIN: Consorzio Idraulico dell’Isola di Ariano, formerly known as Consorzio agli Scoli dell’isola di Ariano (1815-1929)
DATE OF CONSTRUCTION: 1900-1905
DESIGNER: Domenico Donzelli – Antonio Zecchettini
HISTORICAL NOTES:
After multiple requests of the municipalities of Ariano, Corbola and Taglio di Po, an initial plan was drawn up for the restoration of Isola di Ariano, by the civil engineering department of Rovigo in 1886. On the 15th of November 1895, engineer, Domenico Donzelli, from the civil engineering department drew up a new general plan and consortium engineer, Antonio Zecchettini, made important changes to make it work. The project, which was carried out between 1900 and 1916, involved the construction of a primary dewatering pump in Ca’ Vendramin and two subsidiary dewatering pumps in Argana and Cappellona. After they obtained the Ministerial Decree of Approval (in March 1900), the first drainage work was set in motion, with the arrangement the canal network which was needed to bring water to the new plant. The construction of the main dewatering pump, which was contracted out to the company Luigi Medici (Rome), started in September 1900 and ended in November 1905. Ca’ Vendramin was built with the bricks from the Camisotti factory (Santa Maria di Punta), while the mechanical components were assembled in the workshop Cordella (Adria) that installed four Neville centrifugal pumps powered by ten boilers to each pump.
As for the subsidiary dewatering pumps, a current generator designed by Zecchettini and supplied by AEG (Genoa) was built: Ca’ Vendramin was the very first plant in Italy to produce electricity that enabled other plants to work.
In 1921, as a result of a few small essential changes, two of the four main plant pumps were converted to electrical power.
From the moment it was built, the dewatering pump received a great deal of interest and gained attention from Italian and foreign technicians, indeed in 1924 it was praised by a commission of Dutch experts and in 1925 it was presented at an important exhibition in Naples.
Ca’ Vendramin dewatering pump worked until the end of the 1960s, when it was definitively abandoned because of the land subsidence of the area (some technical checks carried out in December 1954 proved that, in just 5 years, the plant had sunk 40 centimetres).
The structure of Ca’ Vendramin has not changed over time: the central body still stands in the shape of a double T, where there was once the workshop and the warehouse, you can see a tall chimney and the living quarters for the engine personnel .
Ca’ Vendramin dewatering pump is currently home to the Museo Regionale della Bonifica, a museum that was created as a result of the Decision of the Regional Council no. 5471 of 17 October 1986 and which from 2010 is managed by the Fondazione Ca’ Vendramin.
