In the event such water user or water users shall not furnish his or their respective share of such labor, material or money within three (3) days after notice so to do, as hereinabove provided, then said manager may, if he elects, notify the association or corporation delivering water into said distributing lateral of the failure, neglect or refusal of said water users or any of them to furnish his or their respective share of such labor, material or money for the proper repair and maintenance of such lateral or for the furnishing and installation of measuring weirs, head-gates and checks, and upon receipt of such notice said association or corporation may, if it chooses to do so, proceed to furnish all labor, material and money necessary for the proper repair and maintenance of such lateral and for the furnishing and installation of measuring weirs, head-gates and checks, or it may, if it chooses so to do, proceed to repair and maintain said laterals and furnish and install such measuring weirs, head-gates and checks as it shall deem necessary or proper for the distribution of water among the several water users. The cost of such repair and maintenance and the cost of furnishing and installing such measuring devices, head-gates, and checks shall be apportioned among the several water users on the basis of benefits derived therefrom by said water users, and the said association or corporation furnishing said funds or doing the aforesaid things or any of them shall within thirty days after completion thereof give each of such water users written notice of the amount or amounts to be paid by him and demand payment thereof. Should the water users or any of them desire to contest the assessment and apportionment made by such association or corporation, appeal may be taken from such assessment and apportionment to the district court in the county where the principal office of said association or corporation is located within ten (10) days after receipt of said notice and demand for payment, in the same manner as in the case of appeals from the boards of county commissioners. In case of appeal any sum or sums determined by said district court to be due, or in the event no appeal is taken then any sum or sums determined by such association or corporation to be due from any water users, shall be paid by such water user within ninety (90) days and the said association or corporation may refuse to deliver any water to any such water user until the amount due shall have been paid in full.
