The grantee shall have the right, privilege and authority to lease, rent or, in any other manner, obtain the use of wooden poles with overhead lines, conduits, trenches, ducts, lines, cables and other equipment and facilities from any and all holders of public licenses and franchises within the city, and to use such poles, conduits, ducts, lines and cables in the course of its business. The grantee shall install its cable on the existing poles owned by other holders of public licenses and franchises with the city whenever possible for the installation of its cable. When installation of cable on poles is insufficient, or when holders of other public licenses or franchises have both installed underground cable, then, in that event, the cable used by the grantee shall be installed underground, and the grantee is hereby given the same rights as the utility companies furnishing gas and electric and telephone service to the residents of the community to use any and all easements dedicated to the city or to the public.
