Treatment of sanitary cold and hot water

The problems that occur in sanitary cold or hot water systems, before any leak, often result in the drawing of coloured water (brownish colour with varying degrees of red, for systems in galvanised steel, and blue-green for systems in copper). Whether preventing scaling or corrosion, the treatment applied to the water must maintain a water quality compliant with the standards that define the composition of water for human consumption.


The processes applied by BWT meet the following requirements:

  • They are authorised by the health authorities.

  • They have a technical recommendation issued by the CSTB.

  • BWT is also CSTBat Service certified for the application and monitoring of its processes.
