In order to know the meaning of the term sewer, it is necessary, first, to discover its etymological origin. In this case, we can emphasize that it is a word that derives from Latin, exactly "sewer", which can be translated as "drain."

The term sewer can be used to refer to tube where the waters are sent with waste of the houses. These ducts are installed underground and are connected to household pipes that allow evacuation of calls sewage water .

The sewers meet in a main collector that allows to transfer these waters to a Sewage plant or to the place of the final discharge. It is important that ducts are projected with a certain slope so that the waters flow by the law of gravity.

This inclination, however, should not be too pronounced since, if the fluids move greatly speed , sewers could erode. It is imperative, on the other hand, that the seals be airtight to prevent seepage and access of rainwater.

It is common for sewers to be blocked or obstructed by the accumulation of elements that are unduly thrown by people. However, throwing any object in a sewer is usually prohibited by law .

It should be noted that, by extension, it is known as sewer to any site or element that is very dirty or that results unpleasant . By example : "I will not sleep in this sewer", “The restaurant in front of the square is a sewer”.

In addition to all of the above, we cannot forget an important audiovisual work that responds to the title of “The sewers of the State”. This is an 80-minute documentary made in Spain by journalists such as Carlos Enrique Bayo and Patricia López that comes to unravel a series of alleged irregularities, illegalities and even corruption that took place within the Ministry of Interior.

Nine months of research work cost that aforementioned documentary, directed by Jaume Roures and with a script by Jaume Grau, which has the testimonies of police officers or officials of the aforementioned ministry.

In the literary field we find, for example, the book "The sewers of 11-M". Ignacio López Bru is the author of this work, published in 2013, which addresses one of the most important tragedies that Spain has suffered in its history. We are referring to the serious terrorist attacks of 11-M of 2004.

This work makes it clear that there are still many aspects of that fact that continue “in the air”, without reaching the general public, because the high spheres of power have done everything possible to hide them and so that not all is known the truth.

In the field of zoology , it is called sewer final section of the intestine of reptiles, birds and others animals . In said cavity, through which the waste is expelled, the urinary and genital ducts also flow out.
