The primary cost and responsibility for water line development shall be that of the owner, subdivider or developer. It shall be the owner, subdivider or the developer's responsibility to purchase and lay water lines from the present water supply to the proposed project and to the boundary of the project farthest from the original water supply line. The city, however, recognizes that in certain instances it may be desirable from the city's standpoint, to have a larger line installed than required to serve the specific development in question. When such a situation exists, it is the city's policy to require the larger line, and to varying degrees, depending on each specific situation, possibly participate in the increased costs necessitated by the larger line.
