I know that all residential bldgs here in the US are NOT at water main pressure... all bldgs have a regulator that drops the pressure below that in the main line under the street. Whether that is the case for industrial bldgs in Italy, I don't know, but I would also think that one would have to use regulators on just about every tap off of the main line in order to maintain a relatively stable pressure in the main line when everyone on the street turns on their sprinklers.

I believe they opened the tap and watched the flow meter needle, and when it reached 1 they stopped. That's how I would do it. It isn't an exact value. Water pressure in a large city in a commercial building is usually stable and the flow rate will not fluctuate much over 18 hours. [snip] - Jed
