(1) The board of directors shall each year on or before a day fixed in the bylaws of the corporation, and if not therein fixed then on or before September 1 of each year, make a computation of the whole amount of money to be raised by the corporation through assessments for the ensuing year for any purposes whatsoever, including maintenance and operation, estimated delinquencies on assessments, principal and interest of indebtedness maturing, and such reserves as may be necessary or provided by the bylaws of the corporation. (2) This amount when so determined by the board shall be an assessment upon all the land described in the articles of incorporation and apportioned to each and every acre or parcel thereof as provided in the bylaws of the corporation or the recorded landowners’ notice subject to its limitations, restrictions and provisions. Unless the board requires the assessment to be paid in advance of the delivery of water, the assessments shall become due and payable in quarter-annual installments, the first of which shall become due three months after the date fixed for the assessment in the bylaws, and if not fixed therein such assessment shall become due within three months after September 1 of each year, and shall bear interest at the rate of two-thirds of one percent per month from the maturity of each installment until paid. Any unpaid assessment and the lien thereof as provided in this section shall be delinquent after the date of maturity of the last installment thereof and may be enforced and foreclosed. Upon the sale of any lands on such foreclosure the corporation or any member thereof or any creditor of the corporation or other person may be a bidder and purchaser. When the bylaws provide rates, tolls, charges, fees, fines and assessments for the use of water or for the use of any of the works of the corporation, the bylaws shall also provide for the time and manner of collection thereof. (3) Notwithstanding the provisions of subsection (2) of this section, the board may certify the assessments including any interest thereon to the county assessor of the county in which the assessed lands lie. Such assessments, if certified and presented after July 15 and on or before the following July 15, shall be assessed against the premises serviced on the next assessment and tax roll prepared after July 15 by the tax assessor of the county in which the corporation is situated. The assessments shall thereupon be collected by the tax collector and distributed to the treasurer of the nonprofit corporation in the same manner as taxes and other charges on the assessment and tax roll are certified, assessed, collected and distributed. (4) The treasurer of the nonprofit corporation shall keep the proceeds of the assessments in appropriate accounts depending upon the purpose of the assessments, and disbursements for the expenses of the corporation shall be paid out of the appropriate account.
