One-off problem
The natural composition of metal-laden water can, in rare cases, give it a brown or red colour. The metal content of the water can also be influenced by travelling through the pipes when the flow rate is increased, for example.
During works on the network, the speed of the water in the pipes can change significantly, stirring up iron deposits.
This water is not harmful to health, but it can cause some inconvenience, such as stains on the laundry. To make them disappear, immediately rewash the dirty clothes.
What can be done to get rid of this colouring?
- Let the water run for a few moments.
- After a long absence, drain the water that has been left to stagnate in the indoor pipes.

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.
