Service branches may be installed by the Bureau, or by a developer with the prior written approval of the Administrator or Chief Engineer, when the Administrator or Chief Engineer determines that such installation will benefit the City. See Section 21.16.160 "Service Installation Fees." If an application is not made for service within 5 years of branch installation, the Bureau may disconnect the service branch at the main. If service is requested after 5 years from date of installation, and has not previously been removed, the Water Bureau shall determine the condition of the service branch. The applicant shall pay for the cost of renewal of the service branch, if required.
