Snow is melting and uncovered a hole in the top of my septic mound?

Question

We just moved into a home and it has a septic mound. It has been covered with snow and now that its melting we found a large hole (about 2 ft in diameter) on the top. What I really want to know is if it just needs to be filled with dirt or is this a sign of a more serious problem? Is it safe to walk on? My kids have been using the mound as a sledding hill? Any answers will be greatly appreciated.

Answer 1

First off, stay off the mound! If a hole has opened up it means the dirt has gone somewhere. The top may have failed and your child could fall into the tank. I'm afraid you will need to have it inspected by a professional.

Second. Never pack down the snow on a mound system. It will freeze! No sledding, no snowmobiles, no grazing animals. A frozen septic is just the worst. (I can attest to that.)

If you just moved in then you need to contact the agent who sold you the home. I know in my county that any home sold must have the septic system checked over first. You may need to bill the previous owner or work it out with the agent.
