Abstract: Sewage pumping stations (PS) with flow control increase the risk of sediment formation inside the pressure pipe due to reduced flow velocitys. The transport of solids was investigated for a PS in northern Germany by means of laboratory tests (sedimentation & erosion), an online total suspended solids measurement and a 1D sediment transport simulation. The results have shown very slow settling processes and extremely low critical bed shear stresses for remobilization. Finally, the present work demonstrated that safe operation of the sewer system and energy-efficient pump control are compatible.
