In accordance with the provisions of this chapter, any municipality within this state may join with other municipalities for the purpose of jointly constructing, acquiring, or operating natural or artificial gas transmission lines, distribution systems, and plants upon such contractual basis as may be desirable and mutually agreeable to the governing bodies of the municipalities concerned. Such lines, systems, or plants shall be jointly operated by a board consisting of such representatives of each municipality as may be agreed by the governing bodies thereof, except that each such municipality shall have at least one member on such board, as selected by the governing body thereof.

Such jointly operated utilities shall be subject to all rules, regulations, and orders of the public service commission in the same manner as privately owned utilities.
