The city may refuse to furnish water and may discontinue service without notice to any premises where apparatus, appliances or equipment using water is found by the manager to be dangerous or unsafe or where the use of water on such premises is found by the manager to be detrimental or injurious to the water service furnished by the city to other consumers, or where the manager finds that negligent or wasteful use of water exists on any premises which affects the city’s water service. The city shall have the right to refuse or discontinue water service to any premises if necessary to protect itself against fraud or abuse. (Ord. 544 NCS §8; prior code §27.28.)
