ICE PIGGING combines the operational advantages of flushing with the cleaning impact of soft pigging. The Ice Pig is a semi-solid that is pumped like a liquid and flows through changes in diameter, bends and fittings without blockage. ICE PIGGING has a minimum impact on operations. The ice pig is simply pumped into and recovered from a hydrant at each end of the pipe section without excavation or modification to the hydrant.


  • Uses a fraction of the water needed for flushing
  • Requires minimal downtime
  • Requires no excavation
  • Injected and recovered through hydrants without modification
  • Effective removal of sediment, debris and bio-film; superior to flushing
  • Reduces disinfectant demand/improves residual
  • NSF Compliant

ICE PIGGING effectively removes sediments, biofilms and foreign matter in pipes, which in turn improves water quality.

It is suitable for:

  • All pipe materials
  • Mains up to 16 inches diameter and higher for special projects
  • Raw water
  • Potable water
  • Sewer network – solution under development

ICE PIGGING is an effective, sustainable tool when used alone or as part of a holistic distribution system water quality and asset management strategy.
