The service line between the main and the service cock or meter may be renewed by the utilities division at its expense upon the request of the property owner only after the line has been in service twenty years or more and has incurred internal corrosion or has otherwise deteriorated to the extent that inadequate or otherwise unsatisfactory service exists. The property owner, however, must first renew the service line between the premises and the service cock or meter before the utilities division will renew its section of the service connection line. This rule shall not apply in the event the service line between the main and the service cock or meter is copper or is demonstrated to deliver an adequate flow at the service cock or meter. The foregoing notwithstanding, a service line between the main and the service cock or meter may be renewed at the utilities division’s expense at any time the utilities superintendent considers that conditions warrant such renewal.
