Over time, sediments, biofilms and debris accumulate in water mains and can create water quality issues such as discolored water or odors which can trigger customer complaints. Ice Pigging is a highly-effective and low-risk technology that uses a thick ice slurry to clean pipes in order to improve water quality, decrease disinfectant demand and reduce energy for pumping.
SUEZ is the sole source provider in the U.S. of Ice Pigging, a unique pipe cleaning technology that provides the operational advantages of flushing and the cleaning impact of soft pigging.
The innovative process involves pumping an ice slurry created on-site into a water main through a hydrant or other existing fitting and using system pressure to push it along the pipe to an exit hydrant. The chemical-free ice pig scours the pipe, removing sediment and built-up deposits, and leaves the pipe clear and obstruction free.
