White water
All technical interventions on the distribution network that suddenly change the water pressure are likely to cause this type of problem (new connection, leak repair, commissioning, change of supply, etc.). As a result of a rapid drop in pressure, fine air bubbles form in the water, giving it a milky/whitish appearance that disappears over time.
Within a minute, the air bubbles rise to the surface and disappear. The water then becomes perfectly clear again. This phenomenon has no effect on water quality.
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.
