Step 2: Development of a cleaning plan

"Planning is the conceptual anticipation of steps that seem necessary to achieve an objective. In the process, it is taken into consideration by which means the objective is to be achieved, how these means are to be applied and how the achieved results are to be controlled." [Wikipedia]

/ 91

The achievement of the objective must not be taken for granted, because, to a large extent, the plan is always based on assumptions. It illustrates the complex interrelations of cause and effect in a drain and sewer system in a simplified form. That is why the ongoing review and optimization of the planning is of essential importance.

The implementation of a demand- and condition-oriented cleaning strategy as a basis for the planning of cleaning methods means turning away from a structural planning towards a dynamic optimization process. Dynamic optimization is developed through a constantly updated and increased operational understanding of the network condition, hydraulics, deposit formation, etc.

Thus, a continuous updating and optimization of the cleaning plan is required. This form of planning goes far beyond common practice to ensure the operability of the drain and sewer system and makes a significant contribution to both the value preservation and optimization of operational costs.
