Where more than one individual consumer is supplied with water through one meter, the individual who applies for service shall be responsible for all charges and the bill shall be computed as though there were a separate metered service for each individual consumer and each used an equal quantity of water consumed, provided, that only one ready-to-serve charge shall be made for each such single-meter installation. There shall be no deductions for vacant premises. For purposes of this section, each one family dwelling unit and each dwelling unit in a two family dwelling or in a multiple dwelling, shall constitute one individual consumer. Further, for purposes of this section, each separate mobile home site within a mobile home court, park or other mobile home complex shall constitute one individual consumer; provided, an automobile trailer court rather than each separate trailer site therein, shall constitute an individual consumer for purposes of this section. (Ord. 1556 § 4, 1973: Ord. B-696, 1946: Ord. B-606 § 35-1, 1944).
