You could operate certain devices such as a rain gauge that allowed you to create artificial rain in a defined area.
Research centres and control laboratories dealing with water in Belgium informed you about their activities.
The biology of surface water was presented by the Natural History Museum.
Photos of the experimental high-pressure boiler, which was the first machine of its kind to operate in Belgium, were also on display.
Following the direction of the visit, on your right, you will reach the area reserved for water collection techniques.
