Indiana Code Title 8. Utilities and Transportation § 8-1.5-2-3

Sec. 3. (a) Subject to restrictions imposed by a bond ordinance, resolution, indenture, contract under IC 8-1-2.2, or similar instrument binding upon it, a municipality may sell or otherwise dispose of any of its municipally owned utilities under this chapter.

(b) A municipality may own, lease, acquire, or construct a utility within the corporate boundaries of the municipality, and within a radius of six (6) miles from those boundaries or any place within the county in which the municipality is located, under this chapter without the consent of any agency other than the municipal legislative body.  Waterworks facilities may be leased from a public utility and operated in conjunction with its municipal waterworks, whether or not the leased facilities are located within the corporate boundaries of the municipality, if the area served by the leased facilities outside those boundaries is contiguous to, or within one (1) mile of, those boundaries.  For purposes of IC 36-4-3, a municipality that leases and operates waterworks serving such an area is considered to be furnishing water service to the area.
