A. Upon the determination that such an emergency exists, the City Manager shall issue a proclamation declaring the emergency and setting out with particularity an order restricting use of water from the system. The order may:
1. Restrict water usage during certain periods of the day or week or according to any orderly and nondiscriminatory scheme; and
2. Prohibit usage not essential to public health and safety. The order may be revised from time to time as the City Manager deems necessary.
B. A duly proclaimed emergency shall continue and the terms of the proclamation shall be in force for thirty (30) days or until such time as the City Manager shall cause to be published a proclamation that the emergency has ended, whichever is shorter, unless the authority by resolution approved by a majority of all its members votes to terminate the emergency and proclamation upon a different date.
