Septic tank risers are excellent additions to your septic tank. They sit on top of the tank and allow easy access for regular cleaning and pumping. Septic tank lids are usually buried 2 to 3 feet or more below the surface. In the past, burying a septic tank lid 3 feet was the best way to ensure safety and security. However, modern risers are secure and safe. Without risers, maintenance can be more difficult and time consuming.
