Cleaning is one of the most important maintenance measures when it comes to ensuring a continuous performance of drainage systems. This module expands on the topics covered in module „D-05 cleaning I“, by providing further knowledge on the applications and limits of flushing methods, mechanical cleaning methods and special methods, such as physical and chemical sewer cleaning. Discussed are both the accessible and non-accessible lines, as well as pressure lines. It concludes with providing constructive solutions for the minimization of solids entry into the sewer system, with the aim of preventing the formation of deposits and hence the reduction of cleaning efforts and frequencies.


Learning content: Flushing methods, mechanical and miscellaneous methods, cleaning of large profiles, cleaning of pressure lines, constructive design measures for the reduction of deposit.
