The regulation of water vending machines is hereby preempted by the state. No county or municipality may adopt or enforce any ordinance which regulates the licensure or operation of water vending machines, unless the local health department authority in consultation with and approval of UDAF, determine that unique conditions exist within the county which make it more appropriate for the county to regulate the water vending machines in order to protect the health or welfare of the public.
