§ 51.05  Users Liable For Bills
   (a)   Where there are different consumers liable for water or sewer charges, and where one or more consumers so liable leave such premises, such consumers so leaving shall not be supplied with water at the new premises occupied by them until all accounts due by such persons shall have been paid.  Where any consumer is liable to the city for such charges at one place and is thereafter located using water at some other place, the water shall be turned off at the new location until all valid accounts past due are paid.
   (b)   Where two or more families or unrelated individuals occupy the same house or apartment, and the water or sewer account is in the name of one family or unrelated individual, if the one in whose name the account stands moves away, the remaining family or unrelated individual is also responsible for the unpaid water or sewer bills.
