This dataset corresponds to the sewage treatment plants. It is made of three geometric classes : sewage treatment plants, sewage treatment plant collection basins and sewage treatment plant discharge points.

This dataset corresponds to water springs. It is made of one geometric classe : the location of water springs in the Brussels-Capital Region.

This dataset corresponds to the atlas of the hydrographic network of the Brussels-Capital Region, in accordance with the Decree of 23 May 2024 classifying non-navigable watercourses, designating regional ponds, determining the content, scope, procedures and deadlines for drawing up the Atlas of the hydrographic network of the Brussels-Capital Region and adopting this Atlas. It is made of ten geometric classes: classified watercourses, unclassified watercourses, bank crests, regional ponds, ditches, engineering structures, sluice walls, watercourse points of origin, cross profiles, embankments.

Brussels-Capital Region: Delineation of the Brussels agglomeration, in accordance with the directive 91/271/EEC concerning urban waste water treatment. The agglomeration is there defined as "an area where the population and/or economic activities are sufficiently concentrated for urban waste water to be collected and conducted to an urban waste water treatment plant or to a final discharge point". It corresponds to the two collecting basins of the waste water treatment plants of Brussels-North and Brussels-South.

This dataset corresponds to the protected sites and natural habitats, in accordance with the ordinance of 1 March 2012 on nature conservation in the Brussels-Capital Region. It is made of six geometric classes : the nature and forest reserves, Natura 2000 sites, the impact zone around Natura 2000 sites,

Brussels-Capital Region: location of various monitoring stations sound levels, managed by Brussels Environment. The monitoring stations are dedicated to ambient noise, road, rail and/or air. Indication of the name (corresponding to the location) and the dominant sound source. Measurement results are available via the module WebNoise on the website of Brussels Environment.

Brussels-Capital Region : location of the different surface water biological quality monitoring sites under the Water Framework Ordonnance and Directive. Surface waters concerned are surface water bodies: Canal, Senne and Woluwe. Monitoring involves a series of biological parameters.

This dataset corresponds to urban agriculture producers. It is made of one geometric classe : the urban agriculture producers's network.

Brussels-Capital Region: The sensitive area to eutrophication is a protected area against the pollution of surface waters caused by waste water. This area matches the Senne river basin. In this area, urban waste water has to be collected and are subject to a stringent treatment before their discharge. It was designated in accordance with the prescriptions of the European Directive 91/271/EEC, by the Regional Decree of 23 March 1994.

This dataset corresponds to hydrography in the Brussels-Capital Region. It is made up of nine geometric classes: drainage basins, arched watercourses, open watercourses, surface water (ponds, marshes, swamps), surface water bodies, springs, right-of-way zone for arched watercourses, non aedificandi zone.
