There are still four water towers in the city of Utrecht. The towers are no longer used, their function - building up water pressure - has been taken over by electric pumps. Pump and tower had the same purpose: to build up water pressure. They are no longer needed, but many water towers are still there, much to Maarten's delight.
The tower in Bilthoven is still completely in its original condition and that is reason enough for Maarten to climb up with a camera and nodding knees.
