I claim the ornamental design for a construction site waste and concrete washout container, as shown and described.
FIG. 1 is a top perspective view from the right side and front side corner of a container showing my new design, the opposite left side being a mirror image of the right side;
FIG. 2 is a top perspective view from the rear side and right side corner of the container of FIG. 1;
FIG. 3 is a top perspective view from the right side and front side corner of the container of FIG. 1, showing the cover lid of the container in an open position;
FIG. 4 is a top plan view of the container of FIG. 1;
FIG. 5 is a top plan view of the container of FIG. 1, showing the cover lid of the container in an open position; and,
FIG. 6 is a bottom plan view of the container of FIG. 1, showing the cover lid of the container in an open position. The broken lines shown on the edges of the container and the container's lid are to show stitching and form no part of the claimed design. The other broken lines are to show environment and form no part of the claimed design.
