NA-05 - Cleaning: Cleaning Strategy and Programme

Operational processes in the cleaning of drains and sewers have a high ecological and economic optimization potential. Activating this potential is the overall objective of this module.

After completing this module, you will have a sound knowledge of:

drawing up cleaning plans with special consideration of the structural condition of pipes and sewers and operating costs;
possibilities for saving operating costs;
differentiation of strategic approaches to cleaning.
