Hii i really need help, can someone tell me why does Dublin use so much water?​

Dublin has the highest rates of domestic water consumption in Dublin are generally recorded in the most affluent suburbs while the lowest are in less well-off neighbourhoods.  

Explanation:

As pressure mounts on households to turn off hoses, resist the temptation to wash windows and cars, and generally exercise good judgment in water use, official figures from metered domestic water supply give an insight into exactly where and how water is used.

I hope that this helpes you :)
