Pierre Patte (1723 - 1814), a French architect under the reign of Louis XV, is credited for having been the first to design a modern sewer system for Paris to manage not only drinking water, but also rain and wastewater. The city gradually became understood as a body through which water ought to circulate without interruption in order to wash it from its impurity, its wastes. Thus, the circulation of air and water became an architectural concern long before the remodeling of Paris by Baron Haussmann in the nineteenth century. Convinced that architecture and urban design can initiate major social transformations, Mayors Sergio Fajardo and Alonso Salazar launched a series of architectural competitions to develop cultural nodes in strategic locations in an attempt to revive civic responsibility and a sense of community. Combining infrastructure and innovative community programs, the municipal government intended to use architecture as a means to fight poverty.
