Where two (2) or more consumers upon the same premises are supplied through one service pipe, the person controlling such pipe, if that fact can be ascertained, and if not, then the owner of such premises, shall pay the water rates for all of such consumers. In such cases separate bills will not be made and a failure to pay any part of the rates due from occupants of such premises shall be sufficient cause for shutting off the water from all of the consumers thereon. (1975 Code § 7-1-7)
