Water Air Water

At A.R.T Europe, we use the Water Air Water method to rehabilitate your pipelines without service interruption and without digging trenches

Water / Air / Water

Discover how the Water Air Water process rehabilitates your pipelines

Water Air Water, a cleaning method for your pipelines. This process uses a combination of compressed air and water to dislodge deposits and ensure optimal flow, without damaging the pipes.

See in the diagram below how this method works, step by step, to ensure a clean, high-performing network.

Environmental impact

A sustainable method

We are aware of the importance of protecting our planet, and the Water Air Water method is fully in line with this approach. By avoiding trenches, we reduce the carbon footprint of our work.

This technique also uses less water than other methods, while limiting the waste generated by the works.

Water / Air / Water process steps

Connecting the mobile unit to the network

We begin by setting up our mobile cleaning unit, connected directly to the network via an injection point (such as a fire hydrant, an air valve or a meter)

Mixing and preparing the Water/Air sequences

This combination of water and air generates controlled pressure that acts directly on the deposits clinging to the walls, loosening them without damaging the pipe structure

Circulating the mixture and removing deposits

Once the water/air mixture is in place, it circulates through the entire pipeline and acts as a mechanical scrub on the inner walls. The compressed air bubbles lift and carry the deposits, which are then flushed out with the water

Sampling for inspection before returning to service

We also take samples of discoloured water to check the quality of the cleaning and make sure no blockages or debris remain.

Frequently asked questions

Yes, the Water/Air/Water process is suitable for pipes from Ø 15 to 300 mm and can be used on both drinking water and non-potable water networks.
The Water/Air/Water process is used to clean and descale pipelines, whether or not they carry drinking water. It removes mineral deposits, sediment and other residues that build up in pipes, efficiently and in an environmentally friendly way.
No, this method is gentle on your infrastructure. The air/water emulsion does not damage pipe walls, even those made of sensitive materials such as PVC or concrete.
