Neb. Rev. Stat. §§ 2-3234
Except as provided in sections 2-3226.11 and 2-3234.02 to 2-3234.09, each district shall have the power and authority to exercise the power of eminent domain when necessary to carry out its authorized purposes within the limits of the district or outside its boundaries. Exercise of eminent domain shall be governed by the provisions of sections 76-704 to 76-724, except that whenever any district seeks to acquire the right to interfere with the use of any water being used for power purposes in accordance with sections 46-204, 70-668, 70-669, and 70-672 and is unable to agree with the user of such water upon the compensation to be paid for such interference, the procedure to condemn property shall be followed in the manner set forth in sections 76-704 to 76-724 and no other property shall be included in such condemnation. No district shall contract for delivery of water to persons within the corporate limits of any village, city, or metropolitan utilities district, nor in competition therewith outside such corporate limits, except by consent of and written agreement with the governing body of such political subdivision. A village, city, or metropolitan utilities district may negotiate and, if necessary, exercise the power of eminent domain for the acquisition of water supply facilities of the district which are within its boundaries.
