Indiana Code Title 36. Local Government § 36-9-25-30

Sec. 30. (a) If the board finds it necessary to build, alter, or repair a sewer, drain, or appurtenance used in connection with sewage works in a public way or other public place in the district or a highway outside its boundaries, it shall file with the works board of the municipality, or the executive of the county in which the municipality is located, a petition and a map showing the route of the sewer or drain or the location of the structure or appurtenance proposed to be built, altered, or repaired, including the part of the public way or other public place to be used in the work.  That body shall then adopt a resolution granting the board the right to use the public way or other public place.

(b) If the board shows in the petition that it is necessary to open or vacate a public way or public place, the appropriate body shall promptly begin the proceedings necessary for the opening or vacation.  Within a reasonable time after the completion of the work, the board shall restore the surface of a public way or public place to the same condition that it was in before the performance of the work.

(c) If the land on which it is necessary to build, alter, or repair a sewer, drain, structure, or appurtenance in connection with the sewage works is already in use for another public purpose or has been condemned or appropriated for a use authorized by statute and is being used for that purpose by the body appropriating it, the public use or prior condemnation does not bar the board from condemning the use of the land for purposes in connection with the sewage works.  However, the use by the board does not permanently prevent the use of the land for the public use or by the body condemning or appropriating the land.  In addition, in a proceeding prosecuted by the board to condemn the use of the land for purposes permitted by this chapter, the burden is upon the board to show that its proposed use will not permanently interfere with the continued public use of the land or by the body condemning it, including its successors.
