What is pluvial?

What Does pluvial Mean

The Latin word pluviālis arrived in Castilian as pluvial . This is the name of what is linked to rain : the water that falls from the clouds.

Air humidity, temperature and atmospheric pressure affect the phenomenon that begins with the condensation of the vapor found in the clouds and ends with the fall of water on the earth's surface. Rainwater is known as rainwater .
The rainwater network , on the other hand, is made up of various elements that are responsible for collecting the water from the rain and transferring it to an appropriate discharge site . In this way, floods in urban areas are avoided .

In general, cities have gutters (ditches) on the sides of the streets that receive rainwater. These gutters act as channels and carry the water to the sinks , which are openings for the water to leave the surface and pass to a subterranean level.
Once underground, rainwater is introduced into conduits (known as drains or drains ): thus, piped, up to its proper mouth, which is usually a river . As can be seen, the rainwater network is essential in any urban development, otherwise the rainwater would not run off.
It is important to note that buildings also have storm drains so that the accumulation of water does not generate moisture in the structures . There are different kinds of storm drains in buildings: pipes, gutters, etc.
When rainwater accumulates on the roof of a building, it stagnates and causes various damages, both to the structure and to the community of neighbors. In addition to the potential seepage that can lead to the growth of fungi and the progressive deterioration of walls, puddles of water attract various insect pests that reproduce at high speeds and can cause discomfort or illness to people and animals that live in the areas. proximities.
Moisture on walls and ceilings can also negatively affect people's health, especially those with a disorder such as asthma. It is highly harmful to breathe in a room where there are fungi , especially if we do it while we sleep. For these and other reasons, storm drainage is absolutely necessary in a building; it is a tool that can avoid many problems of various levels of severity, and in fact it is mandatory in most cities.

It is important to note that after a structural expansion of a building, the storm drain networks must also be expanded. In some cases it becomes necessary to rethink your connections, or it can even be done voluntarily with the aim of improving the system . Patios should be sloped such that water can travel to drains without passing through covered areas; Once the entire route is finished, you must end up in the gutter cordon to continue your way through the urban channels until you reach your previously established destination.
Of course, in some towns there is no public underground drainage system, so the streets can flood even though the houses have storm drains. In a case like this, the negative consequences of moderate rain can be avoided; However, a storm can cause the water level to reach part of the buildings, so that even if they divert the water into the street they suffer a great deterioration .
Climate change has taken more than one city by surprise with certain meteorological phenomena that in the past never took place on their lands. Some of those that did not usually receive significant rains, did not prepare with the necessary pluvial systems for the strong storms that currently hit them, and this can lead to catastrophic floods, simply due to lack of foresight .
