Operational concept – Step 5 (design tables)
The following design table examples are used to determine the required flushing water volume, and the associated levels of surge waves required for the effective execution of preventive and thorough cleaning of sewers.
Tables: Flushing water volume and associated surge levels for surge waves used in the preventive cleaning of circular cross sections ≤ DN 3000 (3000 mm, 120 in) with flushing lengths between 100 and 1,700 m (τe, crit = 3 N/m2) [Dettm2005a]
