For the purpose of making charges, all meters serving the person’s premises will be considered separately, and the readings will not be combined, except that where the Public Works Division, for convenience or operational necessity, elects to install two or more meters instead of one at a central location to serve the customer’s premises, the readings of two or more meters will be combined for the purposes of making charges. [Ord. 962 Art. VII, § 87, 1959; Code 1970 § 13.24.070; Code 1954 § 4-3.152.]
