The city council shall by resolution provide for user charges, the classification of users, applications for service, and use of the service for all municipal utilities providing service within the city. The resolutions will outline the utility's procedure for discontinuance of service, reestablishment of service, and the extension of service to users within and outside city limits. At no time may rate increases for comparable classifications and zones outside the city limits exceed those set within the city limits as per Montana Code Annotated section 69-7-201. (2006 Code)
