How to Care for Your Septic Tank Risers

Septic Tank Riser in Grass

Simple in design, septic tank risers are concrete, plastic, or fiberglass pipes that extend vertically from the septic tank up to ground level. They are typically 12-24 inches in diameter and 2-4 feet in length, depending on how far below ground your tank is buried. Risers create an entry point at ground level that allow your service provider to access the buried septic tank during service visits or inspections.
