After the board of trustees of a dissolving public water district have: (1) paid all debts and obligations of the district; (2) closed up all of the business of the district; and (3) refunded all surplus money, the trustees shall file a statement under oath with the Circuit Court showing all closing transactions. If the Circuit Court approves the statement, it shall issue an order dissolving the district. Upon issuance of such order, the duty of the board of trustees to close up the district business is terminated, and all trustees and officers of the district, whether the terms for which they were elected or appointed have expired or not, shall cease to have any power or authority.
