In the event that two or more meters are placed by permission of the District Manager upon one service connection, they shall be so placed that not one of them shall measure water which has passed through another meter; provided, however, that in cases of commercial, retail office, apartment or multi-family dwellings where the owner thereof desires to have each tenant metered separately, the owner may, with district permission, install one master meter which allows the district to bill the owner solely upon the water consumed through this meter, but which permits the owner to provide and install, at his or her own expense, submeters to measure the quantity consumed by each tenant. In this case, the owner must assume the responsibility for maintaining, reading and billing the submeters.
