Applicants desiring water service in a water benefit district shall pay connection charges as established by Sections 15.08.010 through 15.08.060, and shall, in addition to these charges, pay an acreage charge which shall be established as to amount by dividing the difference between the total installation costs of the major main and the estimated current installation costs of an eight-inch-diameter main by the number of acres in the water benefit district. The determination of this acreage charge as computed by the manager shall be final. The acreage charge provisions of this section shall not apply to properties previously having paid acreage charges.
