Are you embarrassed to ask about this? It doesn't matter, I know that you are interested in this information. For once in a lifetime, anyone has asked this question. But I didn't always get an answer. Indeed, leaving the entrances of our houses, we do not stumble upon rivers of liquid with a specific smell. As it was in the Middle Ages. There is not even a hint of any presence of unpleasant sources. With rare exceptions, in the event of an emergency.
Hello friends, the plumber "Timofey Mikhailov" is with you. Now I will tell you in a joking manner how the drainage system works from our homes. Don't forget to subscribe to awesome content.
Straight to the point. Having gone to the toilet for "negotiations", you start using the toilet bowl "Torpedo - missile"(figuratively speaking), the accelerator and driving force for it is the water from the toilet bowl. First of all, it falls into a vertical pipe. In other words, into the riser.
Flying to the basement of the house, in this pipeline, "torpedo
"dramatically changes the flight path. On the horizontal, the acceleration falls like an avalanche and usually our oval hero disintegrates into "steps". Having turned into particles of different sizes, it begins its long journey through the sewer pipe. The first mark on his way: A house well, in which plumbers are usually caught "free riders"(garbage, hygiene products):These "pokatushki" for our hero "may" resemble water slides. Only the slope is small and our mass smoothly, reluctantly floats to the first pumping station. In it, parts of the torpedo fall into the millstones of centrifugal pumps. That, unfortunately, breaks the factions into "suspension" and it is difficult to track our former missile. But still...
The liquid filled with particles of human life, accelerating, begins to move many kilometers from the point of creation.
Usually, this substance immediately or through an additional pumping station enters the "cunning" pond of treatment facilities, where it passes through the nets, having previously been cleaned of insoluble particles. And then, a multi-ton mass of liquid passes through an army of specially tuned microorganisms. That eat the organic particles of the former "rockets"converting" slurry "into carbon dioxide, water and inorganic compounds ...
Now the bitter truth awaits you. I do not recommend reading susceptible or over eating.
"Rocket", finished her journey. Further, ordinary water, after additional purification, returns back to rivers and lakes. Of these, local water utilities again take water for our needs. That is, the liquid that was once in the toilet, perhaps we have it in a mug with water or tea... Think about it. Such is the cycle of water in nature, such is the truth of life, albeit bitter.
