What is the minimum size requirement for access openings in a septic tank?

Access openings must be large enough to allow inspection and servicing of the tank interior. The minimum size of 15 by 15 inches, or a circular opening of 17 inches in diameter, ensures a technician can access each compartment for visual checks, inserting tools or cameras, and enabling pumping equipment to reach the interior effectively. This size also accommodates the standard riser and cover setup, making servicing practical and safe. In most tanks, there are two openings so each compartment can be accessed, and each opening should meet this minimum.
