After adopting the plans for the construction of the district sewer lines, sewerage disposal, or treatment plant, or parts thereof, and other work in connection therewith, and after determining the property necessary to be acquired, and after the bonds as hereinbefore provided for, have been authorized, the board of directors shall give notice by publication thereof in some newspaper published in said county, calling for bids for the construction of said work, or any portion thereof, and to pay the expense of purchasing and acquiring the necessary property, if any. Said notice shall be published in three (3) issues of a daily newspaper or two (2) issues in a weekly newspaper, the last publication to be at least ten (10) days prior to the date fixed for receiving bids. The notice shall set forth that plans and specifications can be seen at the office of the clerk and that the board will receive sealed proposals therefor, and that the contract will be let to the lowest responsible bidder, stating the time and place for receiving and opening said proposals in public. Said notice shall set forth any reasonable terms and conditions that the board shall deem proper to impose with reference to the letting of the contract and the provisions thereof. Said notice shall further set forth the nature of the performance and statutory bonds required to be furnished. As soon as convenient thereafter the board shall let such contract, either in part or in whole to the lowest responsible bidder, and it may reject any and all bids and readvertise for proposals. The person or persons to whom the contract shall be awarded, shall enter into a bond with good and sufficient sureties, in an amount equal to one hundred per cent (100%) of the contract price for the faithful performance of the contract, and also a good and sufficient bond to the State of Oklahoma for the payment of all labor and material used in the construction of such improvement. All such construction work shall be done under the direction and to the satisfaction of the engineer employed by said board and be approved by the board.
