Paris sewers
Sewers (Fr. Sewers, dt outflows ) are called sewer systems for the disposal of waste water in France.
Famous is the sewer system of Paris is 1200 km long sewage disposal with its 18,000 maintenance shafts and 26,000 monitoring ports ( regards ). There is also an irrigation and drainage system, as it takes up the supplies for drinking and for domestic hot water used, among other exterior cleaning ( His water). They transported annually over a billion cubic meters of sewage and storm water, and is serviced by about 1000 channel workers.
Around 40,000 visitors gain a year by a visit to the Paris Egouts an insight into the historical development of sewerage and water supply of the French capital.
History
The first Sewers of Paris were built around 1350, to include surface water, the first channels and direct it into the rivers. Before the water flowed more bad than good along the streets, collected at the low points and there formed infectious sewers.
On the right bank there was a channel that flowed in two directions, the Ruisseau de Ménilmontant, which was later named Grand egout de Ceinture (large outflow belt). This Bach, whose slope was inconsistent, sprang at the foot of the hill of Belleville, a west slope, followed the foot of the slope and flowed beneath the Rue Gaston- de-Saint -Paul from the Seine, the other took the road to the east and in the moat of the Bastille; he was later extended to the Seine, where it flowed below the Pont d' Austerlitz into the Seine.
On the left bank of the Seine, the surface water in the east could drain into the Bièvre, in the Fosses Saint -Bernard and the Fosses Saint -Victor, in the west in today's egout Guénégaud which skirts under the houses. This egout which is no longer in operation today, spilled out beneath the Tour de Nesle in the Seine.
Between 1350 and 1618 more drains were built, especially the. Along Rue Montmartre, under Charles VI († 1422 ) was walled and roofed, the. Le Ponceau, who crossed the most densely populated part of the city and went to the Porte du Temple in the Grand egout This egout 1605 partially capped, as well as the Rue Vieille du Temple ( the egout Courtille - Barbette ), the Rue Sainte -Catherine, the Rue Saint -Louis and Rue des Filles -du- Calvaire. Another trench, which should absorb the waste water from the halls flowed from the Rue Montmartre egout.
1663, the total length of the covered Sewers of 2353 meters, the Open Sewers of 8035 meters, of which 6218 meters for the egout de Ceinture. Thus they had built more than 10 kilometers of canals or ditches within three centuries. When you consider that the city daily consumed mid-17th century not more than 1700 cubic meters of water, it is clear, up to date at that time were like little hygienic issues.
Towards the end of the 18th century the length of the covered Sewers was 26 051 meters and could be increased to 1824 by only 11,043 meters. The total length of 37 094 meters 1466 meters of open ditches are included.
