Such sanitary district may acquire by purchase, condemnation, or otherwise any and all real and personal property, right of way and privilege, either within or without its corporate limits that may be required for its corporate purposes; and in case any district formed hereunder shall be unable to agree with any other sanitary district upon the terms under which it shall be permitted to use the drains, channels or ditches of such other sanitary district, the right to use the same may be required by condemnation in the circuit court by proceedings in the manner, as near as may be, as is provided in Section 4-17 of the Illinois Drainage Code. The compensation to be paid for such use may be a gross sum, or it may be in the form of an annual rental, to be paid in yearly installments as and in the manner provided by the judgment of the court wherein such proceedings may be had. Provided, all moneys for the purchase and condemnation of any property shall be paid before possession is taken, or any work done on the premises damaged by the construction of such channel or outlet, and in case of an appeal from the Circuit Court taken by either party whereby the amount of damages is not finally determined, then possession may be taken, provided that the amount of judgment in such court shall be deposited at some bank or savings and loan association to be designated by the judge thereof subject to the payment of such damages on orders signed by such judge, whenever the amount of damages is finally determined; and when no longer required for such purposes, to sell, convey, vacate and release the same.
