NA-05 - Cleaning: Cleaning Strategy and Programme

Fundamentals

Context

For the implementation of sewer cleaning, there are no technical guidelines that give the client and operator information regarding the required cleaning cycle, which price-performance-ratio is justified, or which procedure or equipment is best suited to a particular situation.

Cleaning interval frequency depends on a large number of parameters such as:

  • Type of drainage process,

  • Gradient and discharge conditions,

  • Type of deposit and agglomeration, and the likelihood of sewer backup.
