Help!!! About the domestic water tank calculation

[GUO ZHIQIANG]

I want to know where can I find domestic water used of per person per day in differernt types of buildings, for domestic water tank size .
Thank you all in advance

Search engines are great.
Use "domestic water use per person per day <insert country of interest here>"

Examples: (units are litres/day/person)
USA = 227. China = 185. Germany = 123. South Africa = 235. Russia = 248. Iceland = 200.
This is a total of all personal usage - which means some at home, some at work, and (maybe) some at a restaurant or hotel or other venue.

First of all, thanks for your reply.
In fact, what I want is something like this table, which specifies the water needs of each building for the corresponding personnel.
This form was found on the Internet, and I would like to have a more authoritative department or agency to publish it

Think you've found the universal plumbing code.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

thanks for your reply.
I think universal plumbing code donot have this table.

Well at the top of your list it says "as per UPC...."

Anyway, sizing a tank is not a precise art. The actual use of the building makes a huge difference.

It appears that you are in Iraq. The water usage is probably substantially less there.
