I need to put an Extension or "Riser" on top of my Septic Tank. It is 32 Inches down on the low side. I want it hidden, therefore I would like to go with a 24 or 26 Inch Height. One of my questions is Diameter. My concrete cover measures 28 Inches Diagonally. Therefore I should go with a 30 Wide Riser, but I see that they are pretty uncommon and much more expensive. They usually are 24 to 29, it seems. What would be the best way to go? A 28 or 29 and chip off the corners of the Lid? Leave the Concrete Lid off? Open to any suggestions and comments.
Thanks
