Generally all utilities (this includes water and sewer) are the tenants responsibility, but sometimes water and sewer are included. You can either check your lease agreement or if you're still looking at properties to rent, then be sure to ask the owner/property manager and if they say water is included, then make sure this is clearly written in the lease agreement.
Not sure what you mean here but the water has to be paid. If you are renting and your lease says you are responsible for the water bill then yes you have to pay.
