This report concerns the quality of water intended for human consumption, distributed during the 2017–2018–2019 period in the Brussels-Capital Region, with the aim of informing consumers of distributed water. The legal framework is defined by the Decree on the quality of water distributed through the network. This decree sets the quality standards the water must meet and outlines the obligations of the water supplier. As required by the decree, the report covers, at a minimum, all individual water supplies of more than 1,000 m³ per day on average or serving more than 5,000 people. In the Brussels-Capital Region, only one water supplier meets these conditions: VIVAQUA. Therefore, the report is limited to the water distributed by them. Water intended for human consumption is referred to as publicly distributed network water, tap water, or drinking water.
