Compared to conventional high pressure cleaning, surge flushing is economically preferable, if the following conditions are present [Dohma2002a]:

• complicated access for both cleaning vehicles and staff,
• extensive safeguards with respect to traffic control prior to high pressure cleaning,
• need for short cleaning intervals (e.g. monthly),
• very large deposit quantities,
• predominantly loose, unconsolidated deposits,
• long cleaning distances,
• frail pipe condition,
• need for manual removal of solids by suction.
