General information about the  « CERTIBEAU »:

In the case of a new building or the installation of a new tap water meter, the delivery of the certificate follows a successful inspection of your building installation regarding two distinct matters:

> The internal water distribution network

In this context, the certifier verifies that your entire installation complies with the standards and regulations applicable in the Walloon region.

> The sewage network in your building

Whether there is a connection to the public sewer network or domestic wastewater treatment plant, the certifier checks that the sewerage system complies with the town planning permit (building permit) or the environmental permit as well as the various technical requirements.

If the installation complies, the CERTIBEAU certificate for your installation is issued and the connection to the distribution network is completed; the flow limitation placed by the utility company (SWDE, INBW) is removed.
