In this section, “cost of construction” includes the cost of connecting a water main or sewer to the Commission system. If a property owner applies for a water main or sewer in an area in which the Commission determines service is not economically feasible unless the applicant makes a substantial contribution to the cost of construction of the water main or sewer, the Commission may classify the applicant’s property together with adjacent or adjoining properties that could be readily served by the construction required by the applicant as a remote area. The Commission may construct the water main or sewer after: approving the application; receiving payment from the applicant of the contribution necessary for the cost of construction; and imposing the required front foot benefit charge. The Commission may contract with the applicant at the time of the contribution to refund part or all of the contribution from any front foot benefit charges imposed on the property for the water main or sewer subsequently constructed by the Commission and served through the lines of the applicant in the remote area. The Commission shall determine the proportion of the contribution to be refunded and the maximum time of repayment, not to exceed 10 years.
