What is Ice Pigging?

Ice Pigging™ is a highly effective pipe cleaning technique in which ice slurry is moved through the network to remove unwanted material, sediment, or product residues from the pipe.


Historically, pigging has referred to the practice of using mechanical devices known as ‘pigs’ to perform maintenance operations in pipelines. Engineering practice has moved on and now Ice Pigging™ is considered the Best Available Technique for many pipe cleaning situations as it radically decreases the time involved and for the quality of clean.


SUEZ offers an Ice Pigging™ service from mobile delivery units as well as Ice Pigging™ machines that can be permanently installed in factory or industrial plant facilities. This low-risk, clean-in-place process can be applied to a wide range of pipe systems in diverse industrial and municipal applications.

Ice Pigging in action

Ice Pigging™ utilises a two-phase Ice slurry, which is pumpable like a liquid, but forms a semi-solid ‘pig’ within the pipe. The Ice Pig™ is capable of navigating complex pipework which may incorporate changes in pipe diameter, bends, valve systems and other obstructions with no risk of becoming stuck. It is fast, effective and exceptionally low risk (it just melts away), using significantly less water than many other techniques.

Ice Pigging in operation

A highly effective cleaning technique for pipework of large and small lengths and diameters, and can pass through various types of process equipment such as valves and pumps and in different environments; factory, outdoor and underground. A fast and powerful process for commissioning new, decommissioning old and maintaining existing pipe systems. Ideal when you need to remove materials that impact process efficiency, to improve flow performance and achieve quality requirements.

Drinking Water

Ice Pigging™ is a highly effective and exceptionally low-risk method of removing sediment, biofilm and other objects from pressurized water pipes.

Wastewater & Effluent

Ice Pigging™ quickly and efficiently tackles under-performing pipes, removing sewage and other materials with minimal disruption and low-risk.

Industrial Pipe Cleaning

The ice slurry navigates pipe diameter changes, bends and in pipe protrusions, such as sensors and instrumentation, to achieve a high quality clean.


Ice Pigging™ is a quick and efficient line cleaner, propelling the ice slurry through production pipe systems to clean and recover valuable product.

District Heating Networks

A highly effective and significantly quicker method for removing sediment and contaminants as part of the commissioning processor routine maintenance work.
