Mo. Rev. Stat. § 8.440
The board may prescribe the form, details and incidents of the bonds, and make the covenants that in its judgment are advisable or necessary properly to secure the payment thereof; but the form, details, incidents and covenants shall not be inconsistent with any of the provisions of sections 8.370 to 8.450. Such bonds may have the seal of the board impressed thereon or affixed thereto or imprinted or otherwise reproduced thereon. If such bonds shall be authenticated by the bank or trust company acting as registrar for such bonds by the manual signature of a duly authorized officer or employee thereof, the duly authorized officers of the board executing and attesting such bonds, may all do so by facsimile signature provided such signatures have been duly filed as provided in the uniform facsimile signature of public officials law, sections 105.273 to 105.278, when duly authorized by resolution of the board and the provisions of section 108.175 shall not apply to such bonds. The holder or holders of any bond or bonds issued hereunder or of any coupons representing interest accrued thereon may, by proper civil action either at law or in equity, compel the board to perform all duties imposed upon it by the provisions of sections 8.370 to 8.450, including the making and collecting of sufficient rates and charges for the use of the project for which the bonds were issued, and also to enforce the performance of any and all other covenants made by the board in the issuance of the bonds.
