Typically, all septic tanks are located at least 5 feet from the edge of a building and are buried underground, so most septic tanks are outside of the ash footprint. There is no immediate action that a homeowner needs to take in regards to their septic tank, except to identify its location for the debris and ash removal crews who will be working around the site. If the tank is damaged in a way that poses a safety hazard for falling into, then immediate measures should be taken to remove that hazard. Laying down a large piece of plywood over the open hole is a recommended method for addressing this hazard. Caution tape should also be placed to alert people of the hazard. As previously indicated, a damaged septic tank is required to be removed or destroyed in place, but this will typically be required after debris and ash removal is completed.
