Sedimentation 2 SEDIMENTATION BASIN ZONES . Most sedimentation tanks are divided into these separate zones: Inlet Zone . The inlet or influent zone should distribute flow uniformly across the inlet to the tank. The normal design includes baffles that gently spread the flow across the total inlet of the tank and prevent short circuiting in the tank.
