      (5)   Stage 5 triggers - EMERGENCY water shortage conditions.
         (a)   Requirements for initiation. Customers shall be required to comply with the requirements and restrictions for Stage 5 of this plan when the Mayor, or his/her designee, determines that a water supply emergency exists based on:
            1.   Major water line breaks, or pump or systems failures occur, which cause unprecedented loss of capability to provide water service; or
