NA-05 - Cleaning: Cleaning Strategy and Programme

Cleaning strategy

Preventative strategy – Intervals

Necessary minimal cleaning interval frequencies are not defined in sets of standards and of rules. The frequency of cleaning depends on a large number of parameters, as e.g.:

  • Type of drainage process,

  • Sewage composition,

  • Gradient and discharge conditions,

  • Type of deposit and agglomeration and their effect on the operation of treatment works or water pollution control,

  • Likelihood of sewer backup issues.
