The utility may provide water service to adjacent public or private water systems when needed in case of failure of physical system components such as pump failure or a reservoir out of service or similar temporary circumstance, where facilities exist for such interconnection. In such case, the utility shall bill for and be paid for the water used pursuant to the established rate structure as it exists or as otherwise updated from time to time. All requirements of this code regarding water quality and cross-connection control shall be met. The utility shall not serve as a backup supply source to neighboring water systems in case of well failure or other supply disruption unless the neighboring system compensates the utility under separate contractual agreement as a backup supply source, or unless the neighboring water system becomes a permanent utility customer, and makes payment of all appropriate fees and charges. (Ord. 5963 § 1, 2010.)
