Repair Old Septic Tank that Became a Sinkhole
Photo of old septic tank that finally gave up. The house had already connected to city sewer but the plumber did not properly abandon the original septic tank. The top of the septic tank collapsed after the home owner drove over the area with his ridding mower. He did not get hurt but now has a large hole in the yard. We pumped the remaining sewage out of the tank, finish crushing the tank, treat the soil to kill any bacteria then backfill the hole.This process required a permit from the county which was inspected. If a septic tank is not properly abandon when it is no longer in use this could happen. It occurs often.
