Permanent problem
Effective disinfection of tap water is absolutely necessary to prevent the recurrence of potentially fatal infectious diseases. Chlorine is injected into the water at very low levels (safe for your health) to prevent it being contaminated by pathogenic viruses or bacteria between the production site and your tap.
A litre of tap water can contain a maximum of a quarter of a milligram of chlorine.
As chlorine evaporates in the open air (and not in the pipes), its taste disappears very quickly if the water is left to stand in an open jug.
If the chlorine taste and/or odor problem is permanent, please complete the form below specifying the following elements : dates, frequency, duration, time of day and any other element you deem useful.
What is the composition of my tap water?
The composition of the water varies depending on when and where it is collected. Your tap water may be the product of a mixture of water from different sources. Its composition may also depend on the flow rate of each catchment. Regardless of these variations, the drinking water in our network always meets the legal standards.

What quality parameters must drinking water meet? Who sets these criteria?
Tap water must meet a large number of quality parameters. These are set by the standards of the Walloon Water Code. The water from our network is analysed daily to ensure that it complies with the standards.
