The board, in consultation with the committee, shall establish prices for the developed water sold to the districts and electricity sufficient to:
(1) recover the reimbursable preconstruction costs, construction costs, and interest on those costs within the time period specified in Section 73-28-402;
(2) pay for operation and maintenance costs;
(3) accumulate an adequate reserve for repair and replacement; and
(4) allocate the proportionate cost of the project facilities required to deliver the developed water to each district.
