In 1670, the city established the two pumps at the Pont Notre-Dame to raise the river-water, which, elevated "to the height of sixty feet and to the quantity of eighty inches, was conducted into different quarters of the city by pipes six inches in diameter." Two mills which were standing on this site were purchased by the city, which diminished considerably the expense and hastened the completion of the work. These pumps were enclosed in a building of the Ionic order of architecture, the door of which was decorated with a medallion of Louis XIV, and with two figures sculptured in bas-relief by Jean Goujon, one representing a naiad, and the other personifying a river. These had previously ornamented an edifice in the Marché Neuf which had been demolished. An inscription by the poet Santeuil completed the decoration of this building. These pumps were restored and reconstructed in 1708, and finally abandoned in 1854.
The most important reformation effected in the eighteenth century was the reconstruction, throughout its whole length, of the great main sewer and the construction of a reservoir for the water with which to flood it. This was decided upon in 1737, and completed in 1740. Sewers were constructed also in the Rue Vieille-du-Temple and Rue de Turenne, the open ditch Guénégaud was covered over, and the Invalides and the École militaire were supplied with water. A police ordinance of January 9, 1767, forbade the inhabitants to put out in the streets any broken bottles, crockery, or glassware, or to throw them out of the windows; all individuals were forbidden, also, by the eighth article, to throw out of the windows in the streets, "either by night or day, any water, urine, fecal matter, or other filth of any nature whatsoever, under penalty of a fine of three hundred livres." The Parisians objected strongly to this interference with their usual habits, and this question of sanitation remained long unsolved; in 1769, the Contrôleur Général, M. de Laverdy, proposed to establish at the street corners _brouettes_, or small, closed vehicles, in which could be found _lunettes_ for the benefit of the public. "The contractors promised to turn in a certain sum to the royal treasury," says the author of the _Mémoirs secrets_, "which transformed the affair into an impost worthy of being compared to that which Vespasian laid upon the urine of the Romans."
