CWF 'Flushing Bell'

Self-regulating storm tank flushing

  • The Eliquo Hydrok CWF Storm Flush storm tank cleansing system, also referred to as the Hydrok 'Flushing Bell', provides a cost effective solution for the removal of sedimentation by the use of automatic, self-regulated flushing technology.
  • The CWF Storm Flush system is a highly effective non-powered cleaning system for all storm water retention tanks utilising the sewage storm water for the flushing process thus requiring no additional fresh water.

Operating principle

The CWF Storm Flush is a simple method for sediment removal. Storm water is held in reserve in the storage reservoir, filled during the tank filling process. At the end of a storm event and after the system has emptied, the retained flushing water is released via the vacuum break within the flushing vessel. This creates a RFP (Roughing, Fine and Polishing) staged flushing regime which mixes and carries the sediment from the base of the tank to the receiving sump.
