Miss. Code Ann. § 51-29-77

In case it is necessary to do so in order to obtain a proper outlet for the drainage system, the commissioners may construct ditches or do other work beyond the border of their district so as to carry the water to some proper outlet or otherwise to secure the object of the improvement. In that event, they shall have the right to condemn a right of way for such drain or other construction, and the proceedings thereof shall be the same that are now provided by law. Such a ditch or drain beyond the limits of the district shall be the property of the district, and no person not assessed shall have the right to dig any lateral drain connecting therewith without the consent of the commissioners. If such property owner cannot agree with the commissioners as to the price to be paid for the privilege of connecting with such ditch, the board of supervisors of the county where such connection is sought to be made shall fix the amount of such compensation, and either shall have the right to appeal from its findings to the circuit court.
