On this job, we were called after an inexperienced person attempted to remove this tank. Frequently the gauge on an oil tank will break, get stuck, or become covered in sludge, which cause it to not work properly. This tank's gauge showed it to be empty. They quickly found out that the gauge was wrong and the tank was half full. The back legs on the tank gave out while this person was cutting; and, as you may be able the see, the tank is leaning against the sewer pipe. This photo shows the condition of the tank when we arrived. The oil level was only a few inches beneath the horizontal cut. We were able to safely and cleanly remove the waste oil, tank and pipes.
