During the celebration, theaters called tablados are built in many places throughout the cities, especially in Montevideo. Traditionally formed by men and now starting to be open to women, the different Carnival groups (Murgas, Lubolos or Parodistas) perform a kind of popular opera at the tablados, singing and dancing songs that generally relate to the social and political situation. The 'Calls' groups, basically formed by drummers playing the tamboril, perform candombe rhythmic figures. Revelers wear their festival clothing. Each group has its own theme.

Paris in its early history had only the Seine and Bièvre rivers for water. From 1809, the Canal de l'Ourcq provided Paris with water from less-polluted rivers to the north-east of the capital. From 1857, the civil engineer Eugène Belgrand, under Napoleon III, oversaw the construction of a series of new aqueducts that brought water from locations all around the city to several reservoirs built atop the Capital's highest points of elevation. From then on, the new reservoir system became Paris' principal source of drinking water, and the remains of the old system, pumped into lower levels of the same reservoirs, were from then on used for the cleaning of Paris' streets. This system is still a major part of Paris' modern water-supply network. Today Paris has more than 2,400 km (1,491 mi) of underground passageways dedicated to the evacuation of Paris' liquid wastes.
