Missouri Revised Statutes Title XV. Lands, Levees, Drainage, Sewers and Public Water Supply § 248.090. Surveys and plans--adoption thereof

1. It shall be the duty of the board of trustees to make the necessary surveys, and to map out and define the several natural drainage areas in the district, and to lay out a general plan for the drainage thereof; besides the main outlet or outlets, the plan shall embrace branches or submains, necessary for a complete system of principal drains for the entire district. Branch or submains to be paid for out of the general revenue of the district shall not be extended beyond the point at which they will receive the drainage of an area of less than eight hundred acres. Outlets and the larger branches or submains may be open channels, whose general course shall be followed by intercepting sewers, to collect and convey sewage or polluted drainage. The board shall also subdivide the district into convenient subdistricts, not larger than one thousand acres in extent, within which the sewers or drains necessary to complete the drainage shall be constructed at the expense of the subdistrict, as provided in section 248.160.

2. When such plans are complete for a definite district or subdistrict, the board of trustees shall adopt them by ordinance, and such ordinance, when published in one or more newspapers having general circulation in the sanitary district, shall be binding upon all persons, corporations and municipalities; and nothing shall be done affecting the drainage of any part of the district, other than ordinary farm or agricultural drains, by any person, corporation or municipality inconsistent with such plans or without the permission of said board of trustees.
