Dug out the septic cover and had the septic tank emptied this morning. It would be nice not to have to dig out in the future. I was looking for an alternative to spending lots of money on a plastic riser. The depth of hole is 16” and diameter of lid is 23”
I Have this old dryer drum I used for composting I was thinking about repurposing this as a form to pour concrete in and using the earth as the outer form? How thick would it have to be and would the septic ceiling support it? It has some plastic fins that could be removed but the diameter is sufficient for the lid to stay in place at 24 1/2”. Also, if this is a viable solution, would I need to add a seal underneath the pour?
