Notwithstanding the provisions of this article, the treasurer of any county shall disburse to any school district within his county any funds which he may have on hand available for use in the operation of the school district; provided, the governing body of the school district requests disbursement to the school district funds as they become available and; provided, further, that the governing body of the county concurs in the request made by the district. Upon receipt of the school district funds, it may maintain its own bank account for the purpose of making disbursement for the payment of expenses approved by the governing body of the district. Funds received by the school district from the county treasurer which are not needed for immediate disbursement may be invested by the district in interest bearing accounts or certificates of deposit issued by banking institutions or savings and loan associations licensed to do business in this State or in securities issued by or guaranteed by the United States Government. Upon establishing the disbursement method from the county treasurer to the district, the disbursement by the county treasurer shall continue to the district as funds become available unless the procedure is rescinded by action of the governing body of the district or the county governing body.
