In all cases where the city water supply fails, whether from natural causes or accidents of any kind, the city shall not be held liable for any damage of any kind by reason of such failure. In all cases where the size of service and the amount of water used is such that the main pressure in the immediate vicinity is perceptibly affected, it shall be the duty of such person to install a storage tank of sufficient capacity to enable him to operate entirely without water directly from the water mains. In such cases, it shall be the duty of such person to keep a storage of water on hand to meet the demands of such business without imposing any heavy or unusual demand on the water system or appreciably reducing the water pressure in the immediate vicinity. (Ord. 96-5-1, 5-3-1996)
