Whenever the Water Department receives a written request from any property owner to terminate or discontinue water service to any property for the reason that the property is unoccupied and does not require such service, the Water Department shall terminate water and sewer services as of the date such notice is received, and shall make no further charges for water or sewer services until the owner requests resumption of service. Until such request is received, all such charges as provided shall be due and payable.
