The water quality in the project area is being influenced by different sources of contaminants such as households, industry, agriculture and transport.

A number of actions within this project aim to reduce the contamination from agriculture, thus improving the water quality. By doing so, we are aiming to reduce dangerous materials such as nitrates (e.g. though more sustainable use of manure) and measures for fighting erosion at strategic points.

Besides this, water quality is also under pressure from sewer flooding and the run-off from contaminated rainwater. In a number of places, the impact of sewer flooding is being investigated and a strategy developed to reduce the effects. On the Brussels Ring, researchers are examining which materials are primarily found in the run-off rainwater to determine a basis for the development of a purification station.
