I’m looking for the typical water pressure in the Middle East.
I know this can vary but was looking for a general bar figure
Unfortunately i think this might be too vague to ascertain. Also it depends for what ends you need to know? as most of the water is desalinated it is not drinkable either.
Having spent a number of years in the Middle East water pressure was never really an issue from what I recall and also a lot of houses have bore holes for watering gardens and washing cars as it is also quite expensive. If you need to know you might try DEWA for UAE and SAWACO for KSA.
Without knowing specifics I can only offer generic advice i am afraid.
