All drainage districts created by special acts are made drainage districts under Acts 1909, No. 279, with all the powers conferred by the latter and with all the liabilities and restrictions thereby imposed. However, nothing in this section shall be construed as taking away from any improvement district created by special acts any powers which are thereby conferred upon it, nor shall it displace any commissioners or directors of such districts now in office.
