Flooding due to heavy rainfall or high surface water levels.

Enschede and Hengelo provide little capacity to store excess rainwater. Due to the elevation difference between the two cities, water quickly runs to Hengelo during heavy rain. In order to prevent nuisance, the water must be stored temporarily.

The Kristalbad is a multifunctional area that combines water storage with natural water purification and recreation. To improve the biological and ecological water quality, a so called water machine was built.

• Creates an ecological link between Driene and Twekkelo.
• The water machine can be used for extra purification.
• Multifunctional land use.
