Determination of cleaning intervals

Optimization of the operating parameters: Example high-pressure cleaning – Costs

The relationship of the section-dependent and section-independent costs must also be considered in the optimization process (Table).

Section-dependent and -independent costs incurred in high-pressure cleaning
Section-independent costs
(fixed costs)
Factors influencing section-dependent costs (variable costs)
  • Tooling time
  • Refilling of flushing water
  • Approach and setup time of the vehicle
  • Waste disposal
  • Equipment costs
  • ...
  • Nominal size, length and depth of the drain or sewer
  • Water depths and flow conditions in the drain or sewer
  • Type, extent and degree of consolidation of the deposits and agglomerations or obstacles
  • Waste disposal
