(a) As stipulated in section 27-71 above, distribution water mains are extended at the expense of parties other than the department; however, in order to provide a complete adequate water distribution system to all areas of the city, the department has installed and extended, and may continue to install and extend, water mains, generally called trunk mains, within the city limits under any of the following conditions:

    (1)    Through an undeveloped area to bring service to a developed or developing area.

    (2)    To provide an increase in water volume and pressure to a developed area.

    (3)    To close loops in the distribution system to provide circulation and increased volume.

    (4)    To connect and bring service to a water distribution system other than the city's for the purpose of taking over or acquiring such system.

    (5)    For the purpose of replacing, to bring up to city standards, water mains which are acquired from others.

    (6)    Any other reason which, in the opinion of the director, is essential to providing adequate service to an area of the city, yet is not an immediate benefit to the properties adjoining the water main.

    (b) The director shall determine the priority of need and the location of water mains to be installed by the department. Such determination shall consider the actual needs of the area to be served as well as the availability of funds. First priorities shall be given to developed areas which have service that may be inadequate under given conditions.

    (c) When a customer requests a connection which, in the opinion of the director, can be made from a trunk main or other main which has been installed at the sole expense of the department, such customer shall pay to the city a proportional share of the cost of the water main according to the following formulas:

    (1)    For connections two (2) inches or smaller: The number of feet of water main fronting on or otherwise bordering the lot or tract being served multiplied by the department's latest estimated per foot cost of installed six-inch water main of the same material as the main to which the service line is being connected.

    (2)    For connections larger than two (2) inches: The number of feet of water main fronting on or otherwise bordering the lot or tract being served multiplied by the department's latest estimated per foot cost of installed water main of the same size and material as the main to which the connection is being made. In no event shall the customer's cost be less than the department's latest estimated per foot cost for installed six-inch main of the same material nor more than the department's latest estimated per foot cost for installed water main of the size determined by the director as necessary to provide adequate fire protection and service to the area.

    (3)    For connections one inch or smaller to homesteads, farmsteads or recreational property with frontages or other abutting dimensions greater than two hundred (200) feet, the property owner shall, as consideration for such connection:

        a.    Pay an amount equal to the actual cost (at the date of such request) of one hundred (100) feet of six-inch water main; and

        b.    An agreement in a form approved by the city counselor obligating all of the owners of a real property interest in the tract to pay the balance of the actual cost of a six-inch main across the tract at the date future services are requested or the tract is developed for residential or commercial uses.

    (d) The department shall review and update its estimates at least once a year, using the latest available costs of pipe, labor and equipment and shall base the number of hours required on actual installations of a comparative type, which have been made in the recent past.

    (e) When it is apparent that a city installed water main can serve customers on both sides of the right-of-way, only one-half of the above charge shall be assessed to any customer. Where customers' properties front on highway rights-of-way or other rights-of-way where the controlling authority will not permit service crossings, the full estimated cost of the main shall be assessed to any customer.

    (f) The monies received as payment for water mains, as herein provided, shall be placed in the extension, improvement, enlargement and betterment fund established by the city charter, and shall be expended only for the purpose of installing and constructing additional water main extensions.
