Sewage Treatment Operator
Jacqueline Hek is a water treatment operator, she manages the sewage treatment plant on Terschelling. Jacqueline takes us through the process of purifying sewage water into water that is clean enough to enter the sea. She talks about her finds in the sewage treatment plant, what has she learned about humanity? Water sample: sewage samples before treatment.
Process Operator
Hessel Rozenga has a lot of power on Terschelling. He is responsible for all drinking water on the island. From checking the drinking water installation and the pipe from the mainland to Terschelling, to repairs at people’s homes. Hessel explains how water is purified into drinking water. He himself does not drink purified water, but directly from the ground. So why do people still want purified water? And could we also purify sewage water into drinking water?
