Limestone deposit
Generally speaking, tap water of underground origin naturally contains limescale. When water filters down, it passes through several types of soil with different geological characteristics. It then becomes loaded with minerals and trace elements, including calcium carbonate.
The limescale dissolved in the water is not bad for your health. On the contrary, it provides the calcium essential for growth and necessary to prevent decalcification.
Hard water can cause problems in your home because of the precipitation of limescale (calcium carbonate). Limescale is deposited in internal pipes, water heaters, taps, household appliances, washing machines, dishwashers, etc. We recommend that you do not set the temperature of your water heater above 60°.
Light limescale deposits can be easily removed by regularly cleaning with white vinegar, or with special products available on the market.
If your water is too hard, you can choose to install a water softener at home. Please note that you should take certain precautions. You can find more information here.
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.
