Currently, there are several different surge flushing devices used for surge flushing of drains and sewers as well as local drainage structures. According to [Dettm2004a], these devices are categorised into the following four groups based on their structure, technique and equipment:

• Wastewater volume activated flushing system,

• Flushing using a tipping bucket,

• Flushing using a flushing chamber and

• Surge manhole flushing system.
