W. Va. Code § 16-12-8
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 necessary for its corporate purposes. 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 or decree of the court wherein such proceedings may be had: Provided, however, That when such compensation is fixed at a gross sum all moneys for the purchase and condemnation of any property shall be paid before possession is taken or any work done thereon, and provided in case an appeal is taken by either party from the court in which such condemnation is ordered, whereby the damages are not finally determined, the amount of the damages awarded by such court shall be deposited with the clerk of such court, subject to the orders of such court, when the amount of damages shall be finally determined. All condemnation proceedings brought hereunder shall be governed by the statutes prescribing the procedure in case of eminent domain as provided by chapter fifty-four of the code of West Virginia, one thousand nine hundred thirty-one, as now or hereafter amended. Said sanitary district shall have the power to sell, convey, vacate and release the said real and personal property, right-of-way and privileges acquired by it when the same is no longer required for the purposes of said sanitary district.
