Whenever the City Council finds that a potential shortage of water supply is indicated, it shall be empowered to declare, by resolution, that a water shortage advisory exists, and the Water Manager or Superintendent shall, on a daily basis, monitor the supply and demands upon that supply. In addition, the Mayor is authorized to call upon all water customers to employ voluntary water conservation measures (see Addendum to Ord. 8-1988) to limit water use (especially Class III uses) and eliminate the waste of water. This resolution shall be published in the official city newspaper, and may be publicized through the general news media, or any other appropriate method for making such resolutions public.
