When setting up a portable dump tank, it is important to make sure that the liner is spread out evenly in the tank frame and most importantly - into the corners. If the liner is not spread out in the tank frame, then when the first load of water is dumped into the dump tank - the load of water could put undue stress on the frame - possibly bending it. This is especially true when the ground surface is not level. Therefore, the best practice when setting up a dump tank is to take an extra 30-seconds and make sure that the liner is properly situated in the tank frame.
This dump tank frame was bent when the first load of water was dumped into the tank. The liner had not been spread out into the corners of the tank before the water was dumped and there was a slight slope to the pavement on which the tank was sitting.
