Tenn. Code § 7-35-403
Any city or town proceeding under this part is authorized and empowered to condemn property for any and all purposes necessary for the proper completion of the works and the proper operation of the works. Where condemnation proceedings are employed, they shall be in accordance with the established laws of the state in title 29, chapter 16. The cities and towns are authorized to acquire by purchase any existing works, lands, rights, easements, franchises and any other property, real or personal, necessary to the proper completion and operation of the works. Title to property so condemned or purchased shall be taken in the name of the city or town. Where title to any property necessary to the completion or operation of the works is defective, authority is conferred to cure the defects by proper court proceedings. Where a condemnation proceeding becomes necessary, right of possession may issue immediately upon filing proceedings for condemnation, upon the posting of a bond for the value of the property with the clerk of the court.
