Whenever the board of trustees of any sanitary district shall pass an ordinance for the making of any improvement which such district is authorized to make, the making of which will require that private property should be taken or damaged, such district may cause compensation therefor to be ascertained, and condemn and acquire possession thereof in the same manner as nearly as may be as is provided for the exercise of the right of eminent domain under the Eminent Domain Act . However, proceedings to ascertain the compensation to be paid for taking or damaging private property shall in all cases, be instituted in the county where the property sought to be taken or damaged is situated and all damages to property whether determined by agreement or by final judgment of court shall be paid out of the annual district tax, prior to the payment of any other debt or obligation. In the event the board of trustees of such sanitary district shall determine that negotiations for the acquisition property for flood control projects or easements for sewers or sewer improvement over, under or upon certain parcels or tracts of land necessary for the right of way for any improvement which such District is authorized to make have proven unsuccessful and the Board of Trustees shall have by resolution adopted a schedule or plan of operation for the execution of the project and therein made a finding that it is necessary to take such property immediately or at some specified later date in order to comply with the schedule, the Board may commence proceedings to acquire such property or easements in the same manner provided in Article 20 of the Eminent Domain Act (quick-take procedure) .
