N.D. Cent. Code § 61-09-11
Assessments or taxes shall be collected by the county treasurer at the same time and in the same manner as other taxes are collected in the county, except that such county treasurer shall receive in payment to the general fund mentioned in this chapter, for the year in which the assessment is levied, warrants drawn against such general fund as the equivalent of lawful money of the United States, if such warrants do not exceed the amount of the general fund assessment which the person tendering the same owes. Such county treasurer also shall receive in payment of any assessment for any bond fund, or any improvement warrant fund, past-due interest coupons on such bonds or warrants, as the equivalent of so much money of the United States if such interest coupons do not exceed the amount which the person tendering the same owes such fund. All such assessments except for the payment of principal or interest of bonds or improvement warrants collected or received by the county treasurer shall be paid to the treasurer of such irrigation district upon an order signed by the chairman and secretary of the district, and all warrants received by the county treasurer in payment of assessments, as provided in this chapter, may be turned over, as so much money, to the district treasurer on such orders.
