In sewer networks deposition of solids can occur from time to time, due to the intermittent nature of flow. The longer the deposits remain in sewer systems the more likely it is that the sediment properties will change. Eventually these depositions can become cemented (consolidated) especially during dry weather flow (DWF) when the boundary shear stress values are lower than the critical values and the velocity is not enough to carry the sediment along the sewers. The main objective of the present study was to highlight and cover the shortage of methods and approaches in understanding the nature of sediment transport problems in sewers with a build up of permanent deposits. Extensive experiments were carried out in a circular cross section channel (D=305 mm) with various fixed bed thicknesses namely 47 mm, 77 mm and 120 mm, and three different bed roughnesses (0.0
