ABSTRACT:
An improved drop box for septic systems is disclosed including a generally rectangular-shaped, tapered box member, a plurality of invert openings formed on the sidewalls thereof, a locking lid having structural support elements operable to transfer weight carried by the lid to the box's sidewalls, and improved seal means snap-fitted to each invert opening which act to sealingly receive a drain pipe forcibly inserted therethrough. A membrane-type seal plug is provided to block off any unused invert opening. An alternate version of the improved seal means having turbine-blade stiffening means is also disclosed.
