All moneys derived from the issuance of bonds under the provisions of this article, together with any federal grant made in connection therewith, shall be paid to the proper fiscal agent of the supervisory body. Such agent shall deposit such moneys, together with all receipts from electric service or any other operation of the supervisory body as such, in a separate bank account or accounts, separate from all other municipal funds, and shall keep adequate records of all such receipts and their sources. The fiscal agent shall pay out such moneys only on voucher signed by the superintendent. No such voucher for the payment of any such moneys shall be issued except upon the resolution or order of the supervisory body, a certified copy whereof shall be filed in the office of the fiscal agent.
