ᐅ Construction water

Hello!
Our project is slowly getting underway, and we are currently organizing the basic conditions.
We have the following questions and hope for your help:

How many liters of construction water are typically used throughout the building process?
What costs can we expect related to this?
Is it possible to supply construction water from a garden well?
What should be considered in this case, such as water quality or composition?

Thank you very much in advance!

I am wondering, not for the first time, why it is so difficult to use the search function of the HBF?

There are answers to only half of my questions there, but that’s okay, I’m happy to continue following the old thread.
