Use the driving force of pressurized water from the network

[Cuicui]

wasting drinking water to recover a tiny part of what was spent to pump it is a bad idea

Unless it allows you to help out when there is no other energy available.

Electric pump to raise the water in the castle, but not to maintain the network pressure (gravity).

Nice network press!

Certainly but in terms of energy balance it's exactly the same thing ...

Hold Bucheron, you who worked in the water, I had already asked you if you had information on the gray energy of treatment / distribution of water in France ...

In other words: how many kWh EP does it take to transport 1 m3 of drinking water to individuals?

Regarding pressure, it all depends on whether to pump water into a water tower or whether the source located high provides natural pressure.

Yes and no Cuicui, because in it we must count the reprocessing in the case of a sewer ...

Gray energy of the sewerage civil engineering obviously included!

And there is more evolved.

If after use as a driving force we recover the water for normal use, there will be no more in the sewers.

Funny

LOL!

What bullshit, you need a waterproof GSM !!

CUICUI,
Your idea is great in one case
Just below the water tower that supplies the village or the city.
On the main piping.
There, there will be flow and pressure
I am wrong?

You are absolutely right in theory.
In practice, as I clearly indicated at the beginning of this subject, it is only a question of finding simple and inexpensive applications to help out occasionally with tap water (example of the apple press). I don't see the point at all of recovering with a lot of losses, the energy that it was necessary to consume to pump the water at the top of a water tower.
