Our 250-gallon rotationally molded polyethylene holding tank works well in many applications. It is most often used under on-site office trailers, but has also been used for temporary waste storage in other locations as well. The low profile tank has dimensions of 6' x 3' 11 ½" x 18".
Four 3" clean out ports are typically installed on each tank, but custom tanks with as few as two ports may be produced. A uni-seal grommet and threaded PVC connector are inserted in each port. Each tank weighs 100 lbs. See the photo below, or the CAD artwork for details on the tank design.
