The said board of county commissioners, whenever they shall have established any such ditch, drain, or watercourse, shall divide the same into suitable sections, not less in number than the number of owners of land through which the same may be located, and shall also prescribe the time within which the work upon such sections shall be completed, and by whom done. And the said county commissioners shall assess and allow all the fees, costs and expenses of locating and establishing such ditch, drain, or watercourse, and shall apportion the payment of the same equitably among the parties to be benefited thereby. And the county commissioners may prescribe the time within which assessments shall be paid, and may, if they deem it necessary and convenient to the parties, direct the clerk to prepare, for the use of each person having costs to pay and labor to perform, a brief statement, in writing, describing briefly his, her or their apportionment of said ditch, together with the length, depth, and width, and place of the same, amount of costs assessed against such person, when to be paid, and by what time said work shall be completed.
