Fire service connections shall be supplied only through an approved fire service meter or a detector check meter. In the case of premises for which both fire protection service and other water service for such uses as domestic, commercial, industrial or manufacturing purposes is supplied, there may be two service installations made to the premises, one for fire service only and one for other water service. These service connection functions may also be combined in a single service connection with the approval of the utilities superintendent. (Ord. 1237-86 § 49, 1986.)
