Mo. Rev. Stat. § 249.420: Additional lateral sewers in subdistrict.

If, in any such subdistrict, the board of trustees, under the other provisions hereof, shall construct sewers to serve only a part of any such subdistrict and shall thereafter determine that any other part or parts of such subdistrict are in need of lateral sewers, such board shall have power to construct and finance such additional lateral sewers in the same manner that the first sewers in said subdistricts were constructed and financed.
