Lead in your tap water?
Particular attention is paid to the presence of lead in drinking water. At the end of 2013, the European Union set a maximum lead content in tap water of 10 µg/l. We are doing our utmost to meet this standard.

We have invested in replacing all remaining lead connections in the network. For these investments to be fully effective, it is also essential to remove lead from private systems. Most buildings/housing built before the 1960s still have lead indoor pipes.
We therefore encourage you to replace lead pipes in your private system as soon as possible.
Samples are regularly analysed to ensure that the water supplied by our network meets drinking water standards.
This is mainly due to the dissolution of lead in pipes that contain lead (e.g. lead, galvanised steel and some brass).
The extent of this dissolution varies according to several criteria:
Lead is dangerous to health when it accumulates in the body in excessive quantities. It can then cause the disease known as lead poisoning.
In Wallonia, there are no known cases of lead poisoning related to the ingestion of lead via drinking water.
While waiting for your lead pipes to be replaced, you can take some preventive measures:
We are doing everything possible to replace the lead pipes that are still in our network.
The water supplied by our distribution network complies with the standards established at the end of 2013 by the European Union.
If there are lead pipes in your system, reduce the risk of ingestion by following the advice given above.
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.
Water quality must meet the legal standards applicable to drinking water. This quality is strictly controlled, but a problem cannot be ruled out completely.
If in doubt, contact us. We will always look into your query carefully.If necessary, we will send a technician on site for further investigation. They may take water samples. The laboratory analysis will determine any corrective measures to be taken to bring the situation into compliance.

Be careful, after a water cut, the pipes may contain a lot of air. Opening a tap can cause so-called “water hammer”. To avoid damage, we recommend that you first carefully open the cold water tap located just after the meter.
