A sewer is an underground conduit in Maçonnerie intended to run out water of Ruissellement (rain water, water of washing, water of drainage) and the Waste water (waste waters and water valves).
History
The Romans were large manufacturers of sewers, and when they built a city, they thought initially of the establishment of these underground services. When the barbarians became owners of the Gallo-Roman cities, they did not think of maintaining the ancient sewers, which soon were blocked or were lost; the cities then contained true cesspools, stagnated water penetrated the ground, the streets were repugnant and the plague decimated the populations.regularly One started by making trenches in the middle of the main roads, of the deep brooks, boxed, which one recovered of flagstones or which one left with the free air. The Orage S were given the responsability to clean these deep encumbered gutters of refuse of all kinds. It was hardly but at the 12th century that one returned to the ancient method, and that one built underground sewers in masonry under the main roads of the cities.
Gilles Corrozet speaks about sewers found with the Louvre when one rebuilt this palate in 1538. There existed, under the district of the university of Paris, of the sewers (Roman probably) which were a long time used and remade in 1412, because they were out of service. We often saw, by making excavations in the vicinity of buildings of the Moyen-âge, of the remainders of sewers built in beautiful stones of size. The religious establishments and the feudal castles are already provided with sewers laid out well and built as of the end of the 12th century. It often even arrives as these sewers are practicable for men.
According to Purple the Duke
The large sewer of Rome, Maximum Cloaca , would have been carried out by Tarquin Old the in the neighborhoods of the year 600 av. J. - C.
Maintenance
The maintenance of the sewers is sometimes carried out from surface or, generally, in-depth even. The sewermen are the people charged to operate the boats valves, the balls of clearing out, the valves and the remainder of the material. Their mission is double:- to prevent the stopping of the sewers
- to manage the variable water surge
Today, in the modern sewerage systems, technology is everywhere. The balls of cleaning are of diameter just lower than the width of the conduit. The system is built so that the water flow scours the sewer. In Paris, the sewers are on several levels with distribution of the level of the sewers between the various sectors in the event of strong rains.
