SU 5361 is a small wall dividing the sewer in the eastern corridor. It abuts wall 5413 and seems to be abutted by 5332, although it is likely it was constructed contemporaneously with 5332 and possibly with 5331 as a re-use or "renovation" of the existing sewer. A plaster finishing is preserved on its northern and southern faces and continues onto wall 5413, which was clearly necessary for the presence of water.
