Before the Marly Machine was built, the amount of water delivered to Versailles already exceeded that used by the city of Paris, but this was insufficient, and fountain-rationing was necessary.
[1] The Machine de Marly, based on a prototype at the Château de Modave, consisted of fourteen gigantic water wheels, each roughly 11.5 metres or 38 feet in diameter,[3] that powered more than 250 pumps to bring water 162 metres (177 yd) up a hillside from the Seine River to the Louveciennes Aqueduct.
"The chief engineer for the project was Arnold de Ville and the 'contractor' was Rennequin Sualem (after whom the quai by the machine is now named).
Since 1670, Jean-Baptiste Colbert, Louis XIV's Superintendent of the King's Buildings, had opposed several projects, including one proposed by Jacques de Manse [fr], both for reasons of feasibility and that of cost.
[8] A dam at Bezons on the right arm creates a hydraulic head measuring 3.1 metres (10 ft 2 in) high to power the wheels of the Machine de Marly.
They were the only ones to have mastered the mechanism for remote power transmission, the flatrod system necessary for the proper functioning of the machine of Marly.
The Walloon craftsmen went on to become the primary maintenance men essential for the enormous task of keeping the machine in working order.
It included the construction of the machine itself (3,859,583 livres), buildings, aqueducts and water basins, the supply of materials, and the wages of the workers and artisans.
[6] After the end of the work and the successful demonstration, Rennequin Sualem was appointed First Engineer of the King by Louis XIV and knighted.
Pumps in the relay locations were powered by two sets of oscillating timber and metal tie-rod linkages, driven by the river paddle wheels.
Some remnants of Dufrayer's machine are still visible today, but little remains of the original 17th-century masterpiece built by the Sualem brothers, de Ville and Louis XIV.
The overgrown walls of the mid-slope reservoir are visible on the hillside, just adjacent to the cobblestone path that runs straight up the incline.
The paving stones on this 17th century service road are set with their top edges slightly exposed to allow better traction for the horses which hauled loads uphill.
An engraving of the Paris Observatory from the beginning of the eighteenth century shows the wooden "Marly tower" on the right, a dismantled part of the Machine de Marly (the temporary tower replaced by La tour du Levant at the beginning of the Aqueduc de Louveciennes), moved to the Paris Observatory by astronomer Giovanni Domenico Cassini for mounting long telescopes.
