Brussels-Capital Region: localization of the two treatment stations of wastewater and rainwater. The Brussels-North waste water treatment plant (AQUIRIS commissioned in 2007) and the waste water treatment plant Brussels-South (commissioned in 2000).

The UrbIS - Constructions 3D product corresponds to the dataset of three-dimensionally modeled buildings located in the Brussels Region. It includes both buildings and engineering structures. It comprises five classes: (1) the first corresponds to three-dimensional buildings; (2) the second to buildings' faces; (3) the third to three-dimensional engineering structures; and finally, (4) the fourth to engineering structures' faces. The dataset is freely downloadable as a zipped file.

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: localization of the discharge points of the two treatment stations of wastewater and rainwater of the Brussels agglomeration.

Brussels-Capital Region : location of the different surface water 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 chemical, physico-chemical parameters... The code and the name of the monitoring site are given.

Brussels Capital Region: location of the different stations measuring the air quality. Stations of the telemetric, non-telemetric (sampling with laboratory analysis) and weather networks are included. The measured parameters are specified for each station.

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.

Brussels-Capital Region : location of the different groundwater level monitoring sites (or piezometric sites) managed by Brussels Environment under the surveillance monitoring of the groundwater status in accordance with the Ordonnance and the Water Framework Directive. Indication of the analyzed water body, the European Code and the Brussels code of the monitoring site.

Brussels-Capital Region : location of the different groundwater quality monitoring sites managed by Brussels Environment and which results are transmitted through the reporting to Europe (under Article 8 of the Water Framework Directive). Indication of the analyzed water body, the European Code and the Brussels code of the monitoring site. Distinction between two types of monitoring: surveillance monitoring for all groundwater bodies (type_monitoring = 1) and operational monitoring for groundwater bodies identified as being at risk of failing to achieve the objectives of good status (type_monitoring = 2)

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.
