Tenn. Code Ann. § 7-82-109

Notwithstanding any other law to the contrary, any utility district having all or part of its official territory within a county may by resolution agree to accept transfer of all or a part of a water utility system operated by the county pursuant to a previous transfer of such system by a utility district to the county under this chapter, or its operation under a private act, or otherwise, which resolution must contain provisions agreeing to operate such system for the public benefit, and requiring the protection of all rights of bondholders, and which resolution must specifically state that the transfer shall be upon such conditions as may be contained in the county legislative resolution theretofore or thereafter adopted under § 5-7-117. When all conditions of such resolutions shall have been met, the county mayor and president of the utility district shall sign an addendum to the contract, identifying the county and the utility district resolutions of which the contract consists, certifying that all conditions therein have been met, and shall cause such addendum to be published in a newspaper of general circulation within the county at the expense of the utility district, upon which publication the transfer shall thereupon be consummated by operation of law without the need for the execution of any instruments of transfer.
