Water quality in your street
The composition of the water distributed in the Brussels-Capital Region meets the standards imposed by the legislation but may vary according to its origin.
Water hardness reflects the calcium and magnesium content dissolved in water.
This content is expressed in French degrees (°f or °fH) or in German degrees (°dH). The higher the degree, the harder the water (it contains more limescale). Between 0 and 5 °fH water is very soft, between 15 and 25 °fH it is moderately hard, between 25 and 40 °fH it is hard and above 40 °fH it is very hard.
To find out more about water quality in your street, select your postal code and enter your address. Then choose the time period for which you would like to consult the data (in French or Dutch only).
