The city may provide water service to users beyond the city boundaries when requested to furnish such service. The city may provide water service to a customer outside its service area if the property to be served is contiguous to the city's service area, and the user obtains a release from its existing water service supplier. The city may, upon request, release an existing water service user, if the user desires to secure water services from another supplier. (1962 Code § 5-7.01 et seq.)
